Rollo (Norman: Rou, Rolloun; Old Norse: Hrólfr; French: Rollon; c. 835/870 – 933), also known with his epithet, Rollo "the Walker", was a Viking who, as Count of Rouen, became the first ruler of Normandy, a region in today's northern France. He emerged as a war leader among the Norsemen who had secured a permanent foothold on Frankish soil in the valley of the lower Seine. He was a prominent figure among the Vikings who besieged Paris in 885 and led the ill-fated Siege of Chartres in 911.
