What is the significance of the battle between the Arabs and the Franks at Poitiers?

In 732, on October 10, on the road between Tours and Poitiers, in the center of France, there was a battle known as the Battle of Poitiers or the battle of the martyrs’ cohort. The battle was attended by Frankish troops under the command of Karl Martell, who was called for help by the Duke of Aquitania Ed, who had already defeated the Arabs in 721 at the Battle of Toulouse, and the Arab-Berber troops led by Abdur-Rahman ibn Abdallah. As a result of a two-day battle (Frankish sources wrote about one day), the soldiers of the Frankish kingdom inflicted significant losses on the Arabs and plundered their wagon train. At night, the Caliphate’s army retreated. Scientists have different opinions on the impact of the outcome of this battle on the course of historical events. Some adhere to the theory of exaggerating the significance of this battle. At Poitiers, only the large raid army was put to flight, not the invasion army, which only irritated the Omeyad Caliphate. Another camp speaks of the defeat that ended the history of the Arab conquests in Western Europe.
