Papacy/Timelines

This list includes popes and significant antipopes (there are a couple of dozen antipopes at the present day, but their followings are minute). The first column distinguishes them, with question marks where status is uncertain. Blanks in this column are to be understood as the same as the last non-blank entry above them. Details for the first two centuries are historically uncertain.

† Those that reigned in opposition to the popes, commonly referred to as antipopes.
