Another result of feudal customs introduced by the Burgundian princes was the separation of Portugal. For Alfonso VI gave his daughters Urraca and Teresa in marriage to Raymond and Henry of Burgundy, who founded two dynasties: that of Portugal, and that of Castile and León, which began with Alfonso VII. The Kingdoms of Asturias, Galicia, León, and Castile were definitively united under St. Ferdinand, heir of León through his father Alfonso IX, and of Castile through his mother Berenguela. In the same way Catalonia and Aragón were definitively united by the marriage of Ramón Berenguer, the Saint, with Doña Petronila, daughter of Ramiro, the Monk, of Aragón, of whom legend says that he made the famous "Bell of Huesca" out of the heads of rebellious nobles. These three rebellious states, to which the divisions of the peninsula had been reduced, completed the Reconquest; they were not united, to form Iberian national unity, until three centuries later.
