Reconquest ideology framed Islam as destined for extinction

Evidence

In contrast, the work of Alfonso a Spina, written from the point of view of the Spanish Reconquest, sees the physical, and even the doctrinal, struggle of Islam as a gradual subjection to Christendom, bound finally to lead to extinction. The author, credulous of atrocities supposed to have been committed by Jews, is just a little less intolerant of Islam. — Norman Daniel, Islam and the West, 1550
