Popes and Antipopes (999 .. 1503)

Antipopes

Anti-popes were elected by an ecclesiastical faction and later declared uncanonical and invalid. Precise numbers are unknown due to scant documentation in earlier periods. The first anti-pope was probably St Hyppolitus (3rd Century) and the last Felix V, former Duke of Savoy. The number of antipopes range from 25 to 40.

Babylonish Captivity & The Great Schism

Clement V, a Frenchman, moved the Papacy to Avignon after his election (1309-1377). Urban V tried to return, and Gregory XI succeeded shortly before his death. Unfortunately the authorities in Avignon did not immediately accept this, and the Great Schism resulted, from 1378-1415, and they continued to elect a Pope. An attempt to solve this in 1409 resulted in three popes, two being "elected" at Pisa.
