The Muslim group that conquered Spain was the Amazigh, better known by their names Berber (outdated) and Moor (derisive). However, Spain was inhabited by many different types of Muslims.

Finally there were also Slavic slaves that were brought to Spain, but eventually gained their freedom as Muslim citizens.
