The Romans consistently allied themselves with certain barbarian groups outside the Empire, playing them out against rival barbarian tribes as a policy of "divide and rule", the barbarian allies being known as "foederati". Sometimes these groups were allowed to live within the Empire. Barbarians could also be settled within the Empire as "dediticii" or "laeti". The Romans could henceforth rely on these groups for military support or even as legionary recruits. One such group were the Burgundians, whom the Roman Emperor Honorius in 406 had invited to join the Roman Empire as foederati with a capital at Worms . The Burgundians were soon defeated by the Huns, but once again given land near Lake Geneva for Gundioc (r. 443-474) to establish a second federate kingdom within the Roman Empire in 443. This alliance was a contractual agreement between the two peoples. Gundioc's people were given one-third of Roman slaves and two-thirds of the land within Roman territory. The Burgundians were allowed to establish an independent federate kingdom within the Empire and received the nominal protection of Rome for their agreement to defend their territories from other outsiders. This contractual relationship between the guests, Burgundians, and hosts, Romans, supposedly provided legal and social equality. However, Drew argues that the property rights and social status of the guests may have given them disproportionate leverage over their hosts. More recently, Henry Sumner Maine argues that the Burgundians exercised "tribe-sovereignty" rather than complete territorial sovereignty.
