Question: Extract the answer to the question from the following context. Question: Who sparked the war? Context: The crusades were intended to seize Jerusalem from Muslim control. The First Crusade was proclaimed by Pope Urban II (pope 1088–99) at the Council of Clermont in 1095 in response to a request from the Byzantine Emperor Alexios I Komnenos (r. 1081–1118) for aid against further Muslim advances. Urban promised indulgence to anyone who took part. Tens of thousands of people from all levels of society mobilised across Europe and captured Jerusalem in 1099. One feature of the crusades was the pogroms against local Jews that often took place as the crusaders left their countries for the East. These were especially brutal during the First Crusade, when the Jewish communities in Cologne, Mainz, and Worms were destroyed, and other communities in cities between the rivers Seine and Rhine suffered destruction. Another outgrowth of the crusades was the foundation of a new type of monastic order, the military orders of the Templars and Hospitallers, which fused monastic life with military service.

Question: Extract the answer to the question from the following context. Question: When did the comuneros' fight against Charles begin? Context: The vicereine Germaine of Foix brutally repressed the uprising and its leaders, and this accelerated the authoritarian centralisation of the government of Charles I. Queen Germaine favoured harsh treatment of the agermanats. She is thought to have signed the death warrants of 100 former rebels personally, and sources indicate that as many as 800 executions may have occurred. The agermanats are comparable to the comuneros of neighbouring Castile, who fought a similar revolt against Charles from 1520–1522.
