The history of Arab and Islamic rule in the Iberian peninsula is probably one ot the most studied periods ot European history, but the variety and quantity of writing has not escaped the prejudices of the authors. For centuries after the Arab conquest, European accounts of Arab rule in Iberia were negative. European points of view started changing with the Protestant Reformation, which resulted in new descriptions of the period of Islamic rule in Spain as a "golden age" (mostly as a reaction against Spain's militant Roman Catholicism after 1500). The tide of Arab expansion after 630 rolled through North Africa up to Ceuta in present-day Morocco. Their arrival coincided with a period of political weakness in the three centuries old kingdom established in the Iberian peninsula by the Germanic Visigoths, who had taken over the region after seven centuries of Roman rule. Seizing the opportunity, an Arab-led (but mostly Berber) army invaded in 711, and by 720 had conquered almost all of the peninsula. The Arab expansion pushed over the mountains into southern France, and for a short period Arabs controlled the old Visigothic province of Septirnania (centered on present-day Narbonne). The Arab Caliphate was pushed back by Charles Martel (King of the Franks or French) at Poitiers, and Christian armies started pushing southwards over the mountains, until Charlemagne established in 801 the Spanish March (which stretched from Barcelona to present-day Navarre). A major development in the history of Muslim Spain was the dynastic change in 750 in the Arab Caliphate, when an Ummayad Prince escaped the slaughter of his family in Damascus, fled to Cordoba in Spain, and created a new Islamic state in the area.
