Alfonso the Brave, King of Leon, conspired with his older brother to overthrow his younger brother. After conquering Galicia and Portugal, the eldest two fell out. While Sancho had the upper hand at first, Alfonso returned from exile to take the crowns of Castile, Galicia, León and Portugal and proclaimed himself Emperor of Spain.
- By April 1095, Alfonso married Bertha. Chroniclers report her as being from Tuscany, Lombardy, or alternatively, say she was French. Several theories have been put forward regarding her origin. Based on political considerations, proposals make her Berthe de Bourgogne (c1076-1097), daughter of William I, Count of Burgundy or a daughter of Amadeus II of Savoy. She had no children and died in late 1099 (Alfonso first appears without her in mid-January 1100).
