Julius II
Julius II, born Giuliano della Rovere (5 December 1443 – 21 February 1513), was the Pope from 1503 to 1513, and was the successor of Pius III (whose predecessor was Alexander VI).[1]
After becoming the Pope in 1503, he ordered a warrant for the arrest of Cesare Borgia, for the crimes of murder, betrayal, and incest.[2][3] He also learned of the Assassin Order and allied himself with the Order's head, Ezio Auditore, promising to revive Rome to its former glory after the Borgia fled the city.[3]
In the Assassin's Creed: Brotherhood novel, Julius II was against Ezio Auditore killing Micheletto Corella as he thought that Micheletto was securely locked away in his cell, for he says: "No one has ever escaped from the prison in Florence, not from those cells."
