Rollo
10th-century Viking and Count of Rouen

Rollo (Norman: Rou, Rolloun; Old Norse: Hrólfr; French: Rollon; c. 835/870 – 933), or 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. The latter was nonetheless the catalyst for the consequential Treaty of Saint-Clair-sur-Epte, which saw Charles the Simple, king of West Francia, grant Rollo lands between the river Epte and the sea in exchange for Rollo agreeing to end his brigandage, swear allegiance to Charles, convert to Christianity, and pledge to defend the Seine estuary from other Viking raiders.
Rollo's life was recorded by Dudo of St. Quentin. Historians such as W. Vogel, Alexander Bugge, and Henri Prentout have debated whether Dudo's account is historically accurate, and Rollo's origin and life are heavily disputed.
Rollo is first recorded in a charter of 918 as the leader of a group of Viking settlers, and he reigned over the region of Normandy until at least 928. He was succeeded as ruler of the new Duchy of Normandy by his son William Longsword. The offspring of Rollo and his followers, through their intermingling with the local Frankish and Gallo-Roman population, became known as the "Normans".

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
