Read and answer the question at the end of the text: Before the arrival of Hrolf Ganger, there was no difference between the populations of Picardy or those of the Isle of France, which were considered Frankish. Previous Viking settlers had begun arriving in the 880s, but were divided between the eastern colonies (Roumais and Pays de Caux), around the lower Seine valley; and the west, on the Cotentin peninsula, separated by the traditional pagii. The population in these settlements practically remained the same and there were almost no foreign settlers. Hrolf Ganger's contingents, who attacked and eventually settled in Normandy and areas of the Atlantic coast, were made up of Danes, Norwegians, Norse-Gaels, Orkney Vikings, possibly Swedes and Anglo-Danes from the Danelaw under Nordic control. .
