The War of the Lombards (1228–1243) was a civil war in the Kingdom of Jerusalem and the Kingdom of Cyprus between the "Lombards" (also called the imperialists), the representatives of the Emperor Frederick II, largely from Lombardy, and the Eastern aristocracy led first by the Ibelins and then by the Montforts. The war was provoked by Frederick's attempt to control the regency for his young son, Conrad II of Jerusalem. Frederick and Conrad represented the Hohenstaufen dynasty.
