 Peter III had previously married Manfred's daughter, Constance, and it was for this reason that the Sicilian barons effectively invited him.This victory split the Kingdom in two, with Charles continuing to rule the mainland part (still known as the Kingdom of Sicily as well).The ensuing War of the Sicilian Vespers lasted until the peace of Caltabellotta in 1302, although it was to continue on and off for a period of 90 years.
