Alfonso VI of León and Castile

Alfonso VI (c. 1040–1109), called the Brave, was the second son of Ferdinand I of León. Inheriting León in 1065, he fought his brothers Sancho II and García; Sancho's murder at Zamora in 1072 and García's long imprisonment left him ruler of León, Castile and Galicia.

His greatest triumph was the capture of Toledo in 1085, after which he styled himself emperor of Spain. The conquest provoked an Almoravid invasion, which he resisted for the rest of his reign.

But defeat at Uclés in 1108 cost him his heir Sancho. He died in 1109 and was succeeded by his daughter Urraca.
