The Muslim dynasty that established a state in Europe in the 700s was the Umayyad Caliphate, which expanded into the Iberian Peninsula (modern-day Spain and Portugal), establishing Muslim rule in the region known as Al-Andalus. The Umayyad Caliphate's conquest of the Visigothic Kingdom in 711 led to the establishment of a Muslim state that lasted until the 15th century when the last Muslim stronghold in Granada fell to the Catholic Monarchs.
