The siege of Aachen, which lasted from late April or early May until October 1248, was part of the German civil war that began with Pope Gregory IX's proclamation of a crusade against the Emperor Frederick II in 1240. The city of Aachen, which was the traditional coronation site of German kings, supported Frederick II and refused to allow his rival, Count William II of Holland, to enter the city to be crowned. William and his supports besieged the city, forcing it to allow him in, where he was crowned German king.
