Growing opposition to French officialdom and high taxation led to an insurrection in 1282 (the Sicilian Vespers), which was successful with the support of Peter III of Aragón, who was crowned King of Sicily by the island's barons. 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).
