After the Umayyad Muslims had conquered the Visigoths of Spain, they planned an invasion of France. Their advance was finally halted in 732 by Charles Martel (meaning "the Hammer," named this way because of his power on the battlefield).
With this victory, Charles Martel consolidated the power of the Franks. His grandson, Charlemagne (literally "Charles the Great") would conquer a large part of Europe for the Franks and reclaimed the title Roman Emperor.
