failure of his daring scheme. He died the next year in the monastery of Gumiel (1196). The order in Castile appeared to be finished, and the branch of Aragon sought primacy. The Knights of Alcañiz actually proceeded to elect a new grand master, but the grand master still living in Castile claimed his right. Finally, by a compromise, the master of Alcañiz was recognized as second in dignity, with the title of Grand Commander for Aragon. The scattered remains of Castilian knights sheltered in the Cistercian monastery of Cirvelos, and there began to regroup and expand. They soon erected a new bulwark, Salvatierra Castle, where they took the name, which they kept for fourteen years, of Knights of Salvatierra (1198). But Salvatierra itself fell to the Almohad Caliphate in 1209. Summoned by Pope Innocent III, foreign crusaders joined Iberian Christians. An early battle was the reconquest of Calatrava (1212), which was returned to its former masters. In the same year the battle of Las Navas de Tolosa turned the tide of Muslim domination in Spain. Having recovered its stronghold, and resumed the title of Calatrava (1216), the order nevertheless removed to more secure quarters of Calatrava la Nueva, eight miles from old Calatrava (1218). In 1221 the Order of Monfragüe was merged into that of Calatrava. With the decline of Muslim power, new orders sprang up, including the Alcántara in the Kingdom of León and Avis in Portugal. Both began under Calatrava's protection and the visitation of its grand master. This age marks the climax of Iberian chivalry: it was then that King Ferdinand the Saint, after the definitive coalition of Castile and León (1229), in (1235) captured the capital of the old caliphate, Cordova, soon afterwards Murcia, Jaén, and Seville. The European crusade seemed at an end. Encouraged by these victories, Ferdinand's successor, Alfonso X, the Wise, planned a crusade in the East and contemplated marching, with his Castilian knights, to restore the Latin Kingdom of Jerusalem (1272). Calatrava had developed abundant resources of men and wealth, with lands and castles scattered along the borders of Castile. It exercised feudal lordship over thousands of peasants and vassals. Thus, more than once, we see the order bringing to the field, as its individual contributions, 1200 to 2000 knights, a considerable force in the Middle Ages. Moreover, it enjoyed autonomy, being by its constitutions independent in temporal matters and acknowledging only
