of Santiago, Alcántara and Calatrava). '[The Knights] were more committed to religious war than some of their secular counterparts, were opposed to treating with Muslims and carried out raids and even atrocities, such as decapitating Muslim prisoners.' The Battle of Las Navas de Tolosa, known in Arab history as the Battle of Al-Uqab (معركة العقاب), was fought on 16 July 1212 and it was an important turning point in both the Reconquista and the medieval history of Spain. The forces of King Alfonso VIII of Castile were joined by the armies of his Christian rivals, Sancho VII of Navarre, Pedro II of Aragon and Afonso II of Portugal in battle against the Berber Muslim Almohad conquerors of the southern half of the Iberian Peninsula. Hussite Wars The relative importance of the various factors that caused the Hussite Wars (1419–1434) is debated. Kokkonen & Sundell (2017) claimed that the death of king Wenceslaus IV of Bohemia on 19 August 1419 is the event that sparked the Hussite rebellion against his nominal heir Sigismund (then king of Germany, Hungary and Croatia), making it essentially a war of succession. Nolan (2006) named religion as one of several significant causes, summarising the Hussites' motives as 'doctrinal as well as "nationalistic" and constitutional', and providing a series of issues that led to war: the trial and execution of Jan Hus (1415) 'provoked the conflict', the Defenestration of Prague (30 July 1419) 'began the conflict', while 'fighting began after King Wenceslaus died, shortly after the defenestration' (that is, after 19 August 1419). Nolan described the wars' goals and character as follows: 'The main aim of the Hussites was to prevent the hated Sigismund mounting the throne of Bohemia, but fighting between Bohemian Hussites and Catholics spread into Moravia. (...) cross-class support gave the Hussite Wars a tripartite and even "national" character unusual for the age, and a religious and social unity of purpose, faith, and hate'. Winkler Prins/Encarta (2002) described the Hussites as a 'movement which developed from a religious denomination to a nationalist faction, opposed to German and Papal influence; in the bloody Hussite Wars (1419–1438), they managed to resist.' It didn't mention the succession of Wenceslaus by Sigismund, but noted elsewhere that it was Sigismund's policy of Catholic Church unity which prompted him to urge Antipope John XXIII to convene the Council of Constance in 1414, which ultimately condemned Jan Hus.
