ABSTRACT
By the expression Castile we mean the two kingdoms of Leon and Castile, even though their separation was of short duration and the history that we will narrate here relate equally to Castile and Leon. Both kingdoms were united until the eleventh century and were definitively reunited as one kingdom in 1230. The territory to which we now refer included in Innocent Ill's time the greater part of the Iberian peninsula, namely, the present autonomous regions of Castile-Leon, Galicia, Asturias, Cantabria, the Basque Country, Extremadura, New Castile and that part of Murcia and Andalucia reconquered from the Muslims.1
