In the early tenth century a Viking raider, said to have been too tall to comfortably ride a horse, led his band into France. The French king, Charles the Simple, unable to hold them off for long, negotiated a deal that gave the Vikings land in return for their agreement to stop pillaging the French countryside. "Rollo the Walker" became Duke Rollo of Normandy, and a powerful dynasty was begun. In the centuries to come, Normans would conquer Sicily, Southern Italy and England.
