He forced the Danes to accept Christi- anity, and established, as the boundary between their settlements and his own kingdom of Wessex, a line running from London across the island to Chester. But more Danes kept coming, and the Danish invasions con- tinued for more than a century after Alfred's death (901).

By conquest, purchase, or marriage they in- creased the number of their fiefs, and they insured their control over their vassals by promptly destroying the castles of those who refused to meet their obligations. Of these subnations none was more important or interesting than Normandy. The Northmen had been the scourge of those
