Abstract: Between 1147 and 1149 the rulers of the realms of Christian Iberia conducted a series of victorious campaigns against the Muslims of the peninsula. Although it has been widely assumed that Alfonso VII of León-Castile remained militarily inactive during 1148, Christian and Muslim sources, notably the Anales Toledanos and the Ibar of Ibn-Khaldun, indicate that the emperor led an unsuccessful expedition to capture Jaén in that year; and that he sought papal encouragement for his efforts. The Jaén crusade should be viewed in the context of a general Christian offensive backed by the papacy to destroy the power of Islam.
