Feudal social structures, which were never fully established in England, took root in the Marches, which was not legally part of the realm of England. The traditional view has been that the Norman monarchy granted these outright. A revisionist view is that such rights were more common in the 11th century throughout the Conquest, but were largely suppressed in England, and survived in the Marches. Settlement was encouraged: knights were granted their own lands, which they held in feudal service to the Norman lords. Settlement was also encouraged in towns that were given market privileges, under the protection of a Norman keep. Peasants came to Wales in large numbers: Henry I encouraged Bretons, Flemings, Normans, and English settlers to move into the south of Wales.
