The Sack of Rome, then part of the Papal States, followed the capture of Rome on 6 May 1527 by the mutinous troops of Charles V, Holy Roman Emperor, during the War of the League of Cognac. Charles V only intended to threaten military action to make Pope Clement VII come to his terms. However, the Imperial army (14,000 Germans, including Lutherans, 6,000 Spaniards and some Italians) were largely unpaid and mutinied.
