"Significant moment that led to the forming of the Carolingian Empire for the Franks, and halted the advancement of the Moors in southwestern Europe." [Wikipedia: Timeline of the Middle Ages] Tours is a city in the middle of France, just 220 km (132 miles) southwest of Paris. Tours was defended by Charles Martel with an army of 30,000. Abd ar-Rahman al-Ghafiqi of Muslim Spain led an army across the Pyrenees and conquered Acquitaine and Bordeaux. Next, he attacked Tours, but was killed in the battle and his army was defeated.
