Battle of Las Navas de Tolosa

The July 16, 1212 battle of Las Navas de Tolosa is considered a major turning point in the history of Medieval Spain. The forces of King Alfonso VIII[?] of Castille were joined by the armies of his peninsular rivals, Peter II[?] of Aragon and Alfonso II of Portugal in battle against the Muslim Almohad rulers of the southern half of the Iberian Peninsula. Caliph al-Nasir[?] led the Almohad army.

The defeat of the Almohads signaled the beginning of a long decline in the power of the Moors in Spain, and gave futher inertia to the Christian Reconquest begun by the kingdoms of northern Iberia in the century before.
