He's back!


Actually, Benedict came back earlier, right after his godfather Gregory abdicated the papacy. Benedict set himself up as a rival during Clement II's term, and competed with him for validity. When Clement died, Benedict took over the Lateran, and his official third 'term' is considered to have started then, in late 1047.

He was driven out of Rome again by dissidents in the summer of 1048, and never returned. The church excommunicated him shortly thereafter, but the modern church considers all three of his terms as pope valid. It's not clear where or when he died, but he was only 36 when he left the papacy for the final time.
