Alfonso VI "el valiente" (1072-1109)
King of Castile, León, Toledo & Galicia. His nickname means "the valiant".
His reign can be divided in three parts:
After the battles of Llantada (1068) and Golpejera (1072) Sancho conquered the kingdom of Leon, while Alfonso refugeed at the court of the muslim king of Toledo, Al-Mamún.
During this second period, Alfonso repopulated the frontier lands: to do so, he received french inmigrants who settled at those lands: their influence carried out an important cultural task by Europeanizing Alfonso's dominions. Influences from across the Pyrenees showed themselves in the introduction of the Romanesque style in art, the adoption of the Roman instead of the Mozarabic liturgy, the replacement of Visigothic by Carolingian script, and the support that Alfonso gave to Cluniac monasticism, as well as in his reconstruction and safeguarding of the pilgrim road to Santiago.
He claimed the sovereign over the other iberian states, and used the title of "emperor of the two religions" (moslem & christian). Specially, he got involved in the politics of the muslim kingdoms, supporting his friend Al-Mamun, who conquered Valencia or Cordoba. After the death of Al-Mamun (1075), he conquered the kingdom of Toledo. The muslim kings of the South, alarmed for that conquest, and for the "parias" (financial tributes) they had to pay him, clame for the help of the almoravids (a North-African tribe) that entered Spain, commanded by Yusuf. They defeated Alfonso at the battle of Zalaca/Sagrajas (23 October 1086).
