The Northern March or North March (German: Nordmark) was created out of the division of the vast Marca Geronis in 965.[1] It initially comprised the northern third of the Marca (roughly corresponding to the modern state of Brandenburg) and was part of the territorial organisation of areas conquered from the Wends. A Lutician rebellion in 983 reversed German control over the region[2] until the establishment of the March of Brandenburg by Albert the Bear in the 12th century.[3]
