Pope Alexander was a priest for one day and they made him pope. Very interesting guy ~ rather like a combination arbitrage manager, mafia don and guerrilla fighter who could also sail a ship, read, write, and more or less start sticking a small country together.
There have been eight Popes and Antipopes named Alexander.
Pope Alexander I (c. 106 – c. 115)
Pope Alexander II (1061–1073)
Pope Alexander III (1159–1181)
Pope Alexander IV (1254–1261)
Antipope Alexander V (1409–1410) (Considered to be an Antipope; however, the next Pope Alexander took the name Alexander VI due to confusion over Alexander V’s status at the time.)
Pope Alexander VI (1492–1503)
Pope Alexander VII (1655–1667)
Pope Alexander VIII (1689–1691)
