The Umayyad conquest of Hispania was the initial expansion of the Umayyad Caliphate over Hispania, largely extending from 711 to 788. The conquest resulted in the destruction of the Visigothic Kingdom and the establishment of the independent Emirate of Córdoba under Abd ar-Rahman I, who completed the unification of Muslim-ruled Iberia, or al-Andalus (756–788). The conquest marks the westernmost expansion of both the Umayyad Caliphate and Muslim rule into Europe.
Forces commanded by Tariq ibn Ziyad disembarked in early 711 at Gibraltar at the head of an army consisting of Berbers (north-western Africa). He campaigned his way northward after the decisive Battle of Guadalete against the usurper Roderic, after which he was reinforced by an Arab force led by his superior wali Musa ibn Nusair. By 717, the combined force had crossed the Pyrenees into Septimania and Provence (734).
Precisely what happened in Iberia in the early 8th century is uncertain. There is one contemporary Christian source, the Chronicle of 754 (which ends on that date), regarded as reliable but often vague. There are no contemporary Muslim accounts. What Muslim information there is comes from later compilations subject to contemporary ideological influence. The most prominent such compilation is that of Al-Maqqari, which dates from the 17th century. This paucity of sources means that any specific or detailed claims need to be regarded with caution.
