Alfonso is captured, but released into exile, where he seeks refuge in the Taifa of Toledo (under the protection of his vassal, Emir Al-Mamun).
• October 7 – Alfonso VI becomes king of León and Castile, following the assassination of Sancho II. He is bestowed with the title of "Emperor of Spain", and is forced by El Cid (Rodrigo Diaz de Vivar), the standard-bearer of Sancho, to take an oath denying any involvement in his brother's death.
