History of the United Kingdom

The History of Britain, as presented in this article, is an account of some of the happenings that have contributed to the creation of the country now known as Britain.

Introduction
The main body of this article traces some of the developments that influenced the evolution of the British constitution and the welfare of its people. It does so by reviewing  the broad outcomes of sequences of events, often without giving any attention to individual events. The timelines subpage takes a different approach by listing those events that are usually considered to have been most influential at the time. Readers who want to examine any of those events in more detail are invited to make use of the links on that subpage.

Except where otherwise indicated, the sources that are drawn upon are the series of volumes published under the collective title The Oxford History of England, the series  of volumes entitled The Pelican History of England, and the volume entitled The History Today Companion to British History, which are listed on the bibliography subpage.

The division of the text into paragraphs has been adopted solely to split  the account into a series of broadly coherent episodes, and  the headings of the paragraphs are not intended to provide an accurate  indication of their content.

Prehistory
The oldest human remains that have been found in Britain have been carbon-dated as being up to 10,000 years old, and the DNA of a skeleton found in a Cheddar cave has been found to be a close match of a modern dweller in the same area. Since the separation of Britain from the continental landmass did not occur until about  6000 BC , it would be wrong to refer to "Cheddar Man" as British, but the survival of his DNA, despite the subsequent intrusions of conquerors and migrants has been cited in defence of the relevance of ancient  history to current affairs.

The main evidence of prehistoric communal activity  concerns the "Beaker People" of the 2nd and 3rd centuries BC - named after their distinctive ware pottery. The Beaker People kept livestock and cultivated flax and cereals,  used woven fabrics and practiced archery. The wide diffusion of the pottery discoveries suggests that they were a mobile and energetic people, and their grave goods indicate fairly extensive trading activities. . However, the scores of megaliths that are to be found scattered   throughout Britain and Ireland provide the  most visible evidence of  the achievements of  that period. The evidence of Stonehenge suggests that some of the inhabitants were accomplished  civil engineers, and that some had acquired some knowledge of astronomy. The technology that they used is not known - although Bernard Cornwell has provided a plausible fictional account of how they might have solved the problem ,

The Celts (c. 600 BC-49 AD)
The history of Celtic people in Britain is limited by a lack of textual evidence about the period, but it is clear from the archeological evidence that they, too were far from primitive. "Ogham inscriptions" on surviving stone artifacts prove that they used an alphabetic language that modern linguists have been able to decipher, and historians tend to conclude that a Celtic aversion to textual recording must have been the reason for the lack of other textual evidence. The Celts are known to have been migrants from Northern Europe because of their common cultural characteristics, including related languages and similar artifacts. They were all users of metal ploughs and various forms of wheeled transport. Despite the existence of those common cultural characteristics, there is no evidence to suggest that there was any coordination of their activities, or that any Celt thought of himself as a member of any organisation larger than his own tribe . However, the two dozen or so tribes that settled in Britain and Ireland have been categorised into two linguistic groupings - the "Goidelic" group including Irish, Manx and Scottish; and the "Brythonic" group including Breton, Welsh and Cornish - or, more precisely, those were the languages into which they gradually evolved. All of those languages have survived of have been revived, and they constitute one category of the modern legacy from the Celtic migration. (The various modern "Celtic Revival" organisations also lay claim to a range of cultural legacies, some of which, such as "Celtic Music" consist of developments occurring long after Celtic Britain gave way to Roman Britain).

The Romans (49-410)
The period of over a thousand years of Celtic domination was succeeded in parts of Britain by a very different period of about four hundred years of  Roman occupation. Whereas the people known collectively as Celts consisted of a large number of independent or loosely-associated tribes that occasionally coalesced into somewhat larger groupings, the Romans who invaded Britain were a closely coordinated, centrally-managed occupation force. Whereas the Celtic contribution had been largely genetic and cultural, the Roman contribution was largely technological and political. Although the culture of Rome and ancient Greece was to have a profound influence upon British culture, that did not happen as a result of the Roman occupation. Its major contributions at the time were the result of the occupiers' skills in political administration and civil engineering. The inhabitants of those parts of Britain that came completely under Roman control gained the benefits of living in a province of the Roman empire. Those gains included the establishment and enforcement of a legal system, access to Greek and Roman culture, and the  building in stone of  villas, towns and roads. All freeborn Britons became  Roman citizens, and there was eventually no meaningful distinction between being British and being Roman.

The practice of Christianity in the Roman Empire was a capital offence until the Edict of Milan in AD 313, but the martyrdom of St Albans is evidence that it was nevertheless practised in Britain. The recorded attendance of British bishops at the Council of Arles in AD 314 suggests the previous existence of a form of Christian church among the local population, and the adoption of Christianity as the Roman state religion in AD 391 must have helped it to spread.

Where there was not complete Roman control, Celtic society survived and developed along different lines. The Romans did not invade Ireland, they abandoned their early attempts to control what is now Scotland, and they achieved only partial control of England north of the river Trent. In Ireland, in particular there was unbroken development, up to the eleventh century invasions of the Vikings and the Normans, and to some extent beyond those events. In Ireland and in Scotland there was a progressive transition from a fragmented tribal structure into larger groupings that were eventual to lead to integrated national political structures.

Celtic rule and Saxon invasions (c. 410 - c. 600)
After the sudden departure of the Romans, Britain lost nearly all traces of Roman culture. In the course of the following two centuries there was a major decline in the numbers able to read Latin, villas, towns and roads were - with only a few exceptions - gradually allowed to decay, and all stone-working skills were lost. Historians have been unable to ascertain the exact nature and extent of the authority exerted by Celtic rulers in the fifth century. Military and politically control passed eventually to the relatively uncultured Saxons. These likely first arrived in large numbers as hired mercenaries in the middle of the fifth century to help the Celtic rulers defend against raids by Picts and Scots, though Germanic mercenaries of various kinds had been employed by the Romans for centuries. Total conquest was not immediate, however, but was delayed by successful resistance under Ambrosius and Arthur, as a result of which a decaying form of Roman culture survived in the western and northwestern parts of Britain for nearly two hundred years.

Many things remain unknown about the period. It is not known whether the British Christians attempted to convert the Saxon invaders; the historian Bede said that they did not, but his impartiality has been questioned. However, it seems safe to assume that Christian churches survived in the regions of Wales and Cornwall that the invaders did not reach, although their existence may have been unknown to the church officials in Rome. The most significant development, however was the establishment of Christianity in Ireland, and the establishment of monasteries there, where they became centres of learning. Missionaries from the Irish monasteries later carried their religious beliefs and their learning to communities in Scotland and Northern England and played a part in the conversion of the English Saxons to Christianity. That process was completed by the mission of Saint Augustine from Rome and the adoption of the Vatican's doctrines by the Saxon Christians.

The Viking raids and settlement (c. 850 - 950)
There followed a period of about two hundred years during which the name "England" was first adopted, and England was first united under a single ruler. It was also a period during which substantial numbers of Scandinavian settlers were added to the mainly Saxon population, and during which Christianity eventually became the officially established religion. A major part in those transitions was played by the "Vikings" who were raiders from a variety of Scandinavian countries, and "Danes", who were settlers from a similar source who were supported by substantial military forces. At the beginning of the period, the invaders were bands of savage pagan marauders, and by its end - when they finally assumed control - they were civilised, mainly Christian, members of an established Scandinavian empire.

The earliest Viking attacks were upon the Irish ports of Dublin and Waterford, which became Viikung settlements, from which the Vikings took part in Irish power-struggles. The invasions ceased with the Viking defeat by High King Brian Boru in 1014, after which they remained as Irish subjects.

Among the Saxon natives of England, the dominant figure in the first half of the period was Alfred, King of Wessex. It was he who united the country's local leaders in combined resistance to the invaders, and who became England's first king. Alfred combined the qualities of scholar, educator, law-maker, administrator, military strategist and Christian leader. He gave England its first code of law, its first navy and its first well-organised army. His military successes enabled him to negotiate a partition of the country with the Danish leader, Guthrum, and to recapture London.

Late Anglo-Saxon England (c. 950 - 1066)
After Alfred's death, his son Edward and grandson Athelstan continued to gain territory from the Danes but in 990 they counter-attacked in force, reconquered South East England and eventually the whole country. The dominant figure during that period was Canute, who ruled over an empire that included England, Jutland, Norway, Iceland and Greenland. Danish reign over England ended with his death in 1041.

The Normans (1066-1154)
Following the Norman invasion of England, the Normans revolutionised the governance of England mainly by adapting and extending existing institutions. Voluntary agreements under which land tenure was awarded in return for an oath of service to a lord were developed by the Normans into a hierarchical system of compulsory military service , under which the majority of people became serfs, or "villeins", each obliged to serve a lord , who, in turn, was obliged to serve the King by paying taxes and occasionally helping to raise an army. The taxation system was adapted by the introduction of a land tenure basis using survey information recorded in the Domesday book, and by the introduction of systematic enforcement. Edward the Confessor's code of common law was extended by the use of what was to develop into the grand jury system. The concept of the King's peace was extended from its original reference to the protection of the king's house to cover the whole country and symbolised the adoption of crime prevention as a component of government policy. Progress in the development of governance was disrupted by the anarchy resulting from armed combat between claimants to the throne, but was resumed after the agreed succession to the throne by Henry Plantagenet.

Wales was divided into a border region known as "the Welsh Marches" which was under the control of   barons who had taken separate oaths of  allegiance to King, and a self-governing area which was  under the control of native Welsh princes. Although it was nominally part of the kingdom of England, Wales did  not become subject to English law and it was able largely to preserve a separate culture and language for several centuries after the Norman invasion.

A volatile relationship developed between Scotland and England. The English position that Scotland had become a part of the Kingdom of England as a result of the Treaty of Abernethy was often a matter of contention between them, but  various members of the Scottish royal family attended the English royal court and became familiar with  Norman culture and governance. As a result, a Norman-style feudal system was set up in Scotland and Norman noblemen were invited to become part of it. There followed three centuries during which raids, invasions and battles (known as Scotland's Wars of Independence), were interspersed with periods of peaceful trade and the interchange of culture and population.

The Plantagenets (1154-1485)
Neither the futile and immensely damaging "100 Years War" over the succession to the throne of France, nor the disruptive but relatively trivial "Wars of the Roses" over the succession to the English throne, had any significant effect in themselves upon the subsequent course of English history, but there were other developments that did. Principal among them were the changes to the constitution and to the mobility of labour, and the conquest of Ireland.

The system of serfdom under which peasants were forbidden to leave the villages of their parents' birth came gradually to an end in the course of Plantagenet period, not as a result of promises to abolish it to the rioters of the "Peasants Revolt", nor by any subsequent legislation, but under pressure from popular demand and the disruptions to the labour force caused by the enormous population loss during the "Black Death"

Limited but significant steps toward the creation of a system of representative government were taken during the 13th century. The Magna Carta set up an independent assembly  - later to be termed a "parliament" - that purported to serve the interests of the country, with powers of control over the conduct of government,, and its initial membership of 25 barons was broadened by Simon de Monfort's Provisions of Oxford, by the constitution of the "Model Parliament" during the reign of Edward I, and subsequently by the 1429 Franchise Act which restricted voting in elections to freeholders of land worth more than 40 shillings. By the end of the Plantagenet era, the system had acquired the power to propose legislation and had divided into two houses, with the House of Commons assuming control over taxation.

The Magna Carta also contained a statement of civil rights which is held to be the founding principle of the English legal system, and to be one of the precursors of the Universal Declaration of Human Rights

English governance was strongly influenced by the Church, and its Canon Law enforced by the imposition of burning at the stake as a punishment for heresy. Expressions of dissent by William of Occam and John Wycliffe had little influence, but a small underground movement of dissenters known as the "Lollards" somehow survived their designation as heretics.

The conquest of Ireland, that had started with an expedition organised by an English baron in collaboration with an exiled Irish king, was acknowledged by the submission of the Irish kings to the lordship of Henry II, and was given further formal expression when Prince John, Lord of Ireland, was designated King of England.

There continued to be a volatile and often hostile relationship between England and Scotland, aggravated by Scotland's "Auld Alliance " with France.

The Tudors (1485-1605)
England under the Tudors experienced major changes to its constitution, to the prosperity of its people, and to their outlook. The Tudor era completed its conversion from a collection of self-sufficient local communities into a nation with a well-established system of governance. There was a renewed growth in population and a  substantial  increase in both prosperity and poverty. There was also an upheaval of belief, intellectual enquiry and exploration, including a transition from the dominance of  Roman Catholicism to the acceptance  of other creeds and the transition from exclusively  deductive modes of reasoning to the acceptance of the  inductive method - as well as the undertaking of numerous voyages of discovery. Finally there was an increase in the importance of relations with its neighbours, and a number of attempts were made to incorporate Ireland, Scotland and Wales into a united British kingdom.

The status of Parliament was increased under the Tudors. The foundations for a limited system of representative government had been laid during the Plantagenet period and, in England at least, government under the Tudors came to be widely accepted as an instrument devoted mainly to the creation and preservation of social order. Tudor monarchs often made ruthless use of their power to rule by proclamation, but were nevertheless inclined to make use of parliament in support of claims to rule by consent and, although parliaments were mainly compliant, there was significant growth in the influence of the House of Commons over the creation and endorsement of legislation. The administration of law, although formally a royal prerogative, became the province of professional lawyers, exercising a significant degree of independence from the crown, and the practice of petitioning the king to remedy injustice developed into the legal system of "equity" , operating alongside, and sometimes in conflict with the rapidly development system of common law. Access to the law, which was traditionally confined to freemen, expanded rapidly with the disappearance of serfdom.

There was also substantial growth of the population and of the country's prosperity. Nearly all of the population was engaged in subsistence agriculture and cottage industry, but there were signs of the growing influence of small-scale industry and commerce. The principal manufactured products were textiles which were mostly the result of household activities, but there was also a growing output of  other extracted or manufactured   products such as coal and iron. . On the commercial side, there were several companies of merchants who were promoting exports of English textiles to Europe and sponsoring voyages of exploration and the creation of settlements in America, and there were several joint stock companies financing those activities. The growing prosperity for some that was attributable to those activities was accompanied for others by unemployment and abject poverty. Their suffering has been attributed to bad harvests, land enclosures the dissolution of the monasteries and the ending of the paternalist protection afforded by the feudal system. The early Tudor reaction to the resulting roving bands of indigent "vagabonds", was "poor law" legislation for their restraint and punishment, but it changed  towards the end of the period to the introduction of a national system of limited support for the "deserving poor". Notwithstanding the growth of the English economy under the Tudors, the corresponding increase in the welfare of its inhabitants is also considered to have been limited by the inflation attributed mainly to the debasement of the currency under Henry VIII.

The adoption of inductive methods of enquiry during the Tudor era provided the intellectual foundation for later scientific advances. The departure that took place from the hitherto exclusive employment of deduction from accepted axioms as a method of intellectual inquiry, was promoted in England by Francis Bacon - thought to have been inspired by the work of his Italian contemporary, Galileo - and subsequently set out in his tract on "The Advancement of Learning". Bacon's fantasy The New Atlantis contained an account of an imaginary institution that is said to have inspired the later creation of the Royal Society.

The break with Rome was probably the greatest upheaval of the Tudor era, and it was certainly a major cause of dissension for centuries to come. It caused demonstrations of mass protest at the time and was adamantly opposed by influential figures such as Thomas More, but was brought about with the assent of parliament and without sustained opposition in the country. Acceptance of the rejection of allegiance to the Roman Catholic Church and the adoption of Anglicanism as the country's official religion has been attributed partly to the accessibility of the bible to the ordinary people and   a revival among them of the Lollard movement, partly to  an anti-clerical climate of opinion arising from a surge of protest against corrupt Church practices led by Martin Luther,  partly to a nationalist aversion to interference by foreigners, and partly to the skillful presentation of his case  by Henry VIII's spin-doctors.

England's foreign policy also underwent major changes. Whereas, before the break with Rome, Henry VIII was an enthusiastic supporter of the Pope and an ally of Spain in their campaigns against France, after the break with Rome, it was the  opposition of the Pope and the military threat from  Spain that dominated  policy thinking. There was also a major change in relations with Scotland. A Scottish policy of helping France by frontier raids brought it  defeats so drastic as to prompt the suspension of the "Auld Alliance", and the subsequent rapprochment with England was facilitated by Scotland's break with Rome and by family relationships between the English and Scottish royal families. Towards the end of the Tudor era, successful negotiations between Elizabeth I of England and James VI of Scotland created an atmosphere  of widespread acceptance of the prospect of union between the two countries. No such atmosphere was created in Ireland. English governance was limited a relatively small area, outside of which the country was united only to the extent of a shared resentment of English incursions. The English establishment developed no consistent Irish policy beyond the achievement of pacification of a hostile population to an extent sufficient to prevent the use of Ireland by the Catholic governments of Spain and France as a base for a military action against Protestant England.

The Stuarts (1605-1714)
The Stuart era was a time of intellectual turmoil, involving challenges to traditional beliefs about politics, religion, and the nature of the physical universe. The spirit of scepticism about the legitimacy of authority that had been generated by the European reformation was further stimulated in England by the power struggle  between the Crown and Parliament, and by the end of the Stuart era a political consensus had emerged. There was, by then, a general acceptance of the previously contentious proposition that the legitimacy of government is conditional upon the consent of the governed. The formulation of that principle by John Locke in terms of the conditional relinquishment of individual freedom, provided a reassuring justification for the outcome of that power struggle. The transition to fully representative government was far from complete, however. The idea of rule by a representative body elected by universal (male} franchise, that had been vigorously mooted during the life of the Commonwealth, had been rejected as a threat to stability. Sovereignty had nevertheless passed from the Crown to a representative assembly, even if its electorate was confined to property-owners.

It was also a time of shifting religious beliefs. Among the sources of authority that were challenged was the Anglican Church of England, and a variety of non-conformist religious movements took hold during the Commonwealth period, notably the Puritans (who had a learned spokesman in John Milton) and including the Quakers. The constitution made a brief return to authoritarianism after the Restoration, when non-conformists (then called "dissenters") were ostracised and persecuted, after which there was a gradual return to something approaching tolerance of nonconformist forms of protestant belief. Roman Catholicism survived as a minority belief, but Catholics were generally feared as possible foreign agents, were excluded from public office and were often persecuted.

The philosopher Bertrand Russell has observed that, as a result of the scientific discoveries of the Stuart era "the outlook of educated men was transformed" and there was "a profound change in the conception of man's place in the universe" . Among British contributions to that revolution were Isaac Newton's laws of motion, Harvey's discovery of the circulation of blood and Robert Boyle's chemical discoveries.

There were also some changes that had little to do with the intellectual turmoil, the most of important of which was the creation of "The United Kingdom of Great Britain" by the passing - toward the end of the period - of the Act of Union with Scotland as a result of which the two countries were to be governed by the same parliament as well as the same king. In addition, there were colonial acquisitions in the West Indies and North America - including twelve of what were two be the original thirteen American colonies. Ireland had already accepted colonial status and Wales had long been deemed to be part of Britain.

The Hanoverian period (1714-1914)
Among the major developments of political thought during the eighteenth and nineteenth centuries were an extension of the concept of human rights, and a rejection of the medieval concept of the state as a moral regulator of personal and commercial conduct - in favour of the laissez-faire concept, in which the only legitimate role of government is the preservation of order and the promotion of progress. Those two developments were promoted consecutively in Thomas Paine's "Rights of Man" and in the two essays "On Liberty" and "Representative Government" by John Stuart Mill . The economic case for laissez-faire was developed analytically in the eighteenth century in Adam Smith's "Wealth of Nations", was promoted politically in the nineteenth century by the economists of the "Manchester School" ,  was given legislative expression by Robert Peel in the repeal of the Corn Laws , and political expression in a split in the Conservative Party and the formation of the Liberal Party. At the same time, a developing labour movement was finding intellectual expression ranging from Utopian socialism to communism, and popular expression in the campaigns of the Chartists and in the development of trade unions

There was also an unprecedented growth of national prosperity, and the conversion, in the course of the industrial revolution, of a predominately agrarian economy into "the workshop of the world". Improved engineering products, processes and designs were applied to cloth making, mining, steelmaking,  railway construction and shipbuilding. The major productivity increases that then occurred have been attributed mainly to those innovations, and in particular to the development of the steam engine to the stage at which it could be used to power any  machine. They were put to use in a factory system that was manned by migration from rural communities, and paid for by the  investment of savings that had been generated by agricultural rents. The fact that industrialisation came first to Britain (a fact that has been attributed also to the social and economic circumstances of the time ) accounts for the establishment of London as the world's leading financial centre; for the emergence of the pound sterling as its  leading currency;  and for the  contribution of the Bank of England's management of the gold standard to international financial stability. By the end of the period, however, there were signs that Britain's commercial dominance was being eroded by changing economic cirumstances and rapid industrialisation in Europe and America.

At the end of the 19th century the British Empire occupied 20 percent of the world's land area and contained 23 per cent of its population. During the previous 150 years the British possessions in colonial America were expanded and consolidated,, following the success of the French and Indian War, Canada in the north and the Thirteen Colonies on the eastern seabord were ceded by France to Britain; and, following the American Revolution, the Thirteen Colonies were ceded to their inhabitants to form the United States of America. Later in the 19th century, Canada's self-governing status as a dominion of the British Empire was formally recognised. In the Far East, the East India company had been expanding its trade with India since its foundation in 1600, and had gained increasing military and administrative control there after the collapse of the Mughal empire and of France's departure following the Seven Years War. After the Indian Mutiny of 1857 those functions were transferred to the British crown, and Queen Victoria was proclaimed Empress of India. British settlements in Australia and New Zealand were consolidated to form colonies and then to become self-governing dominions. Aquisitions elsewhere in the Far East included Burma, Malaya, Singapore and New Guinea. In Africa, Cape Town was annexed in 1806 and  British settlements in South Africa were  extended  eastward to form the colony of Natal and, following the Boer War, the  Union of South Africa became a self-governing dominion  of the British Empire. Elsewhere in Africa, Britain occupied or annexed Egypt, the Sudan, and what are now  Kenya, Uganda, Somalia, Zimbabwe, Zambia, Botswana, Gambia, Sierra Leone, Nigeria, Ghana and Malawi.

Notwithstanding its other achievements, Britain in the nineteenth century failed to achieve social harmony among its own people. In the words of Benjamin Disraeli there were
 * "Two nations between whom there is no intercourse and no sympathy; who are ignorant of each other's habits, thoughts and feelings, as if they were dwellers in different zones or inhabitants of different planets; who are formed by different breeding, are fed by different food, are ordered by different manners, and are not governed by the same laws ... THE RICH AND THE POOR"..

Among the working class majority, grinding poverty accompanied by exclusion from the political process generated bitterness and resentment, and among the rich minority  there were fears that generous state relief of poverty would encourage indolence, and that if the uneducated poor were given the vote they would misuse it - possibly  to destroy  property rights. In the latter part of the nineteenth century, however, vigorous public demonstrations, combined with a growing acceptance of humanitarian liberalism, persuaded Parliament to introduce legislation that raised the proportion of adult males entitled to vote from about 25 per cent to about 60 per cent, followed by compulsory publicly-funded education and, in the pre-war twentieth century, by publicly-funded health and (limited) unemployment insurance.

The First World War (1914-1918)
The historian, A J P Taylor has argued that before August 1914, the average Englishman could go through life hardly noticing the existence of the state, but that, from that date the history of the people merged with the history of the state . Five million British men joined the armed forces, and three quarters of a million of them were killed. For those at home, movement was restricted, conditions of work were prescribed, food was rationed, the press was censored, "daylight saving" was introduced, and licensing hours were reduced. Government policy was affecting everyday life as never before. Public expenditure rose in the course of the war from about 15 per cent of national income to over 70 percent (and it never fell below 30 per cent thereafter), and the domestically-fiancednational debt rose from 25 per cent to 130 per cent of national income. Having lent about £1800 million to its allies and borrowed £1300 million from abroad, Britain never recovered its former status of international creditor.

The war also brought about changes in social relations. Attitudes to women were changed by the fact that two million of the took the place of the absent men; and among men, the social division of Disraeli's "two nations" was substantially eroded  by shared experiences in the trenches. By the end of the war, the exclusion of women and of 40 per cent of men from the political process had become politically unthinkable.

The inter-war years (1918-1939)
Of the two major constitutional development of the inter-war years, one  was the introduction of universal suffrage, which can be thought of as completing the evolution of the Westminster system of representative government. Post-war governments continued to use the wartime "cabinet" system, under which policy decisions were centred upon a body made up of selected heads of government departments and headed by a powerful "prime minister". A doctrine of "collective responsibility", under which cabinet members were expected to resign if they felt unable to support cabinet decisions, together with a system of party discipline maintained by parliamentary whips, ensured that the cabinet decisions of a government that had an assured  parliamentary majority were seldom overturned. The other major constitutional development was the initiation of a process of transferring effective sovereignty to selected countries of the British Empire that were thereafter to be termed Dominions - initially as members of the Empire, and subsequently as members of the British Commonwealth. That process started in 1922 with the transfer of effective sovereignty to the Irish Free State following a bloody Irish War of Independence, and in 1931 it was applied to Canada, Australia, New Zealand, and the Union of South Africa.

Among major political developments was the the transition from a two-party to a three-party structure of parliamentary representation, following the pre-war birth of the Labour Party. People began to speak of a left-right spectrum of political opinion stretching from communism to fascism, in which the Labour Party stood to the left of centre, the Conservative Party to the right of centre, and the Liberal Party somewhere in between. There was also a spectrum of opinion within each party, but leading party members were usually dissuaded from airing their differences in public by traditions of party loyalty and party solidarity.

But the developments that most affected the lives of the British people were mainly economic. There was a substantial growth in the gross domestic product between 1918 and 1939, but it was interrupted by two setbacks, during each of which there was a sharp rise of unemployment. The first setback occurred in 1920, and is thought to have been policy-generated. Budgetary policy in the aftermath of the war was directed at the reduction of the national debt, as a result of which there was  an abrupt change from a strongly expansionary fiscal stance  in 1918, to a strongly deflationary stance in the following two years, and there was  severe recession during which the unemployment rate rose to over 11 per cent. Following the resumption of growth, and after the return to the gold standard at an uncompetitive rate in 1925, the second setback started in 1929, triggered by events in the United States and Germany. The economy suffered a "slump" (the term used in Britain to denote its share of the Great Depression) during which the unemployment rate reached 17 per cent. In 1931, the government was forced to leave the gold standard, after which the economy showed a steady recovery, although the unemployment rate did not fall below 10 per cent until 1937.

The great depression stimulated the study of the economy as an interactive system, and the development of the science of macroeconomics. A leading figure in that development was John Maynard Keynes. His attempts to influence the conduct of economic policy on both sides of the Atlantic were unsuccessful, but "Keynesianism" was to have a profound influence on the conduct of post-war governments. He was persuaded to join the Treasury at the beginning of the war, and his team there made a major contribution to the technology of economic statistics, and one of them, Richard Stone, has been credited with the founding of the system of national accounts that has since been adopted internationally.
