Kamehameha III

Kamehameha III (born Kauikeaouli), (August 11, 1813–December 15,1854) was the King of Hawaii from 1824 to 1854. He was Hawaii's longest-reigning monarch. His full Hawaiian name was Keaweaweula Kiwalao Kauikeaouli Kaleiopapa and then lengthened to Keaweaweula Kiwalao Kauikeaouli Kaleiopapa Kalani Waiakua Kalanikau Iokikilo Kiwalao i ke kapu Kamehameha when he ascended the throne. He was Hawaii's first Christian king and it was under him that Hawaii transitioned from a secular Hawaiian monarchy to a Christian constitutional monarchy with the signing of not one but two of Hawaii's Constitutions in 1840 and 1852. He was the longest reigning monarch in the 99 years of history of the Kingdom, ruling for 29 years and 192 days, although in the early part of his reign he was under a regency by Queen Kaahumanu and later by Kaahumanu II.
