The Battle of Guadalete took place in 711 AD in southern Spain. It was a significant conflict between the invading forces of the Umayyad Caliphate and the Visigothic army led by King Roderic. The battle marked the beginning of the Muslim conquest of the Iberian Peninsula. The Visigoths were defeated, leading to the rapid expansion of Muslim rule in Spain and the establishment of the Al-Andalus region. This event had lasting effects on the culture, religion, and politics of the area, shaping the history of Europe for centuries to come.
