After the better part of a year when Anti-Pope Benedict X held the seat, Nicholas II was installed in early 1059. He was again helped by powerful women, this time by Agnes of Poitou (who was acting as HRE Regent for Henry IV). He held the seat until his death in the summer of 1061.

Oh, by the way - Nicholas II's portrait here is from a very small, very cracked fresco. Not much detail to be had!
