Answer:
The Battle of Poitiers (known by European historiography as the Battle of Tours not to be confused with the Battle of Poitiers of 1356) took place on October 10, 732 between the forces commanded by the Frankish leader Charles Martel and a Muslim army under orders of the governor of Al-Andalus Abd ar-Rahman ibn Abd Allah al-Gafiqi, near the city of Tours, in present-day France.
During the battle, the Franks (Christians) defeated the Muslim army and al-Gafiqi was killed. This battle halted the Muslim expansion northward from the Iberian Peninsula and is considered by many historians as an event of great historical importance, having prevented the invasion of Europe by Muslims and preserved Christianity as the dominant faith for a period in which Islam was submitting much of the territories of the Roman Empire of the East and had ended up conquering the Persian Sassanid Empire, an expansion that began in 632 after Muhammad's death.
