"My name is Rollo (Norman: Rou, Rolloun; Old Norse: Hrólfr; French: Rollon; died in 933) I was a Viking who became as Count of Rouen, I've became the first ruler of Normandy, a region in today's northern France. I emerged as a leading warrior figure among the Norsemen who I had secured a permanent foothold on Frankish soil in the valley of the lower Seine after the Siege of Chartres in 911. Charles the Simple, king of West Francia, granted them lands between the mouth of the Seine and what is now Rouen in exchange for me agreeing to end my brigandage, swearing allegiance to me, religious conversion and a pledge to defend the Seine's estuary from other Viking raiders."
