of its survival, even after Frankish conquest, until the ninth century. 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. Gundioc's son, Gundobad (r. 474-516), began commission for his kingdom's legal codification in 483, which his son and successor, Sigismund (r. 516-532) completed. The laws deal mostly with inheritance and monetary compensation for physical injury. The earlier work, antiquae, and the later additions, novellae, together make the whole Burgundian Code. The Franks began attacking the Burgundians in 523 and completely defeated them by 534, when Sigismund's brother, Godomar (r. 532-534), fled and left the kingdom to be divided amongst Frankish rulers. However, the Franks kept Burgundian law in practice. Contents of the Lex The Burgundian Code consists of two sets of laws, the earlier Book of Constitutions or Law of Gundobad, or Liber Constitutionum sive Lex Gundobada, and Additional Enactments, or Constitutiones Extravagantes. The laws of both parts are intended to govern the personal relations between individuals. The Law of Gundobad (Titles II-XLI) is a compilation of existing
