Abd ar-Rahman I (born 731; ruled from 756 through his death circa the year 788) was the founder of a Muslim dynasty that ruled the greater part of Iberia for nearly three centuries. The Muslims called the regions of Iberia under their dominion al-Andalus. Montgomery Watt said that the name al-Andalus "was used exclusively for that part of the peninsula under Muslim rule".
