Rollo (Göngu-Hrólfr, or "Walking Rolf") was a towering, formidable Viking leader, known for being too large for a horse, earning his nickname by walking into history. He transitioned from a feared raider terrorizing France to the shrewd founder of Normandy, accepting land from the Frankish King Charles the Simple in 911 AD in exchange for defending the realm and converting to Christianity. He became the first ruler of this powerful duchy, blending Norse and Frankish cultures, and establishing a dynasty whose descendants, like William the Conqueror, would profoundly shape European history, notes talesofvalhalla.com.
