In 1139, after an overwhelming victory in the Battle of Ourique against the Almoravids, Afonso Henriques was proclaimed the first King of Portugal by his troops. According to the legend, Christ announced from heaven Afonso's great deeds, whereby he would establish the first Portuguese Cortes at Lamego and be crowned by the Primate Archbishop of Braga. In 1142 a group of Anglo-Norman crusaders on their way to the Holy Land helped King Afonso Henriques in a failed Siege of Lisbon (1142). In the Treaty of Zamora in 1143, Alfonso VII of Leon and Castile recognized Portuguese independence from the Kingdom of León.
