The Umayyad conquest of Hispania<span> was the initial expansion of the </span>Umayyad Caliphate<span> over </span>Hispania<span>, largely extending from 711 to 788. The conquest resulted in the destruction of the </span>Visigothic Kingdom<span> and the establishment of the independent</span>Emirate of Cordova<span> under </span>Abd ar-Rahman I<span>, who completed the unification of Muslim-ruled Iberia, or </span>al-Andalus<span> (756–788). The conquest marks the westernmost expansion of both the </span>Umayyad Caliphate<span> and </span>Muslim<span> rule into Europe.</span>
