Even though the crusade did not finally materialize, a large number of foreign knights came to the Iberian Peninsula. They included Raymond and Henry of Burgundy, who married Alfonso VI's daughters Urraca (1090) and Teresa (1094), respectively, which led to the establishment of the Anscarid and Capetian dynasties in the peninsular kingdoms. Some of the crusaders unsuccessfully besieged Tudela in the winter of 1087, before withdrawing. That same year, the king crushed a revolt in Galicia aimed at releasing his brother García II.
