The Moors were the Muslims who lived in the Maghreb and on the Iberian Peninsula, Sicily and parts of Southern France in the Middle Ages. In Europe, the word was often used for indigenous European people whose ancestors were converted to Islam, although Islam was not actually invented until 700 A.D., so the religion of the Moors who are indigenous to Europe was something else.
Umayyad Muslims were the ones who captured and named Al-Andalus, which means land of the Vandals. The majority of Moors in Iberia were native European populations who converted to Islam due to the Arab conquests of the peninsula. These Moors were forcefully converted to Catholicism after the Christian reconquest of the Iberian Peninsula in completion of the period popularly known as the Reconquista.
