Marklo was according to the Vita Lebuini antiqua, an important source for early Saxon history, the tribal capital of the Saxons where they held an annual council to "confirm their laws, give judgment on outstanding cases, and determine by common counsel whether they would go to war or be in peace that year." After the conquest of old Saxony by Charlemagne in 782 the tribal councils of Marklo were abolished.
