Moors Invade Spain

In 711, a mixed army of Arabs and Berbers led by Tariq ibn Ziyad crossed the Strait of Gibraltar from North Africa and landed on the Iberian Peninsula. Within a few years they had overthrown the Visigothic kingdom, and Muslim-ruled territory, known as al-Andalus, would shape Iberian politics, culture, and religion for centuries. The traditional figure of "700 years" is a simplification: Muslim power peaked early and shrank gradually, ending only with the fall of Granada in 1492.

The Visigothic kingdom, centered at Toledo, had ruled most of Iberia since the fifth century. By the early 700s it was weakened by disputes over royal succession, and sources suggest that rival factions contested the throne after the death of King Wittiza. Meanwhile, the Umayyad Caliphate had swept across North Africa, and its governor in Ifriqiya, Musa ibn Nusayr, had brought the Maghreb under Muslim control, with many Berbers converting and joining the armies.

Tariq, usually described as a Berber commander serving Musa, landed near the rock later called Jabal Tariq, or Gibraltar, "Tariq's mountain." The Visigothic king Roderic marched south to meet him, and the two forces clashed in a battle usually placed in the south of the peninsula, often associated with the Guadalete River area. Roderic was defeated and apparently killed. Our main accounts were written generations later, in Arabic and Latin, and mix fact with legend. The popular story of Count Julian betraying Roderic, for example, is of doubtful reliability, and even the size of Tariq's force is uncertain.

After the victory, Tariq advanced on Toledo and other cities, and Musa arrived with reinforcements in 712. Many towns apparently surrendered through treaties that allowed Christians and Jews to keep their property and religion in return for tribute, which helps explain the speed of the conquest. Muslim forces pushed north of the Pyrenees until a defeat at Poitiers (Tours) in 732 halted their advance into Frankish Gaul, though raids continued.

The consequences were lasting. Al-Andalus became a province of the Umayyad Caliphate, and after the Umayyads fell in Damascus, a surviving prince, Abd al-Rahman I, founded an independent emirate at Córdoba in 756. Later the Caliphate of Córdoba became one of medieval Europe's largest and most sophisticated cities, a center of scholarship, architecture, and trade. Christian kingdoms survived in the northern mountains, and the long, uneven process later called the Reconquista gradually pushed south. The era left deep marks on Spanish language, agriculture, architecture, and memory, and it remains a subject of debate over how much cooperation and how much conflict defined life in medieval Iberia.
