Germanic kingship is a thesis regarding the role of kings among the pre-Christianized Germanic tribes of the Migration period (c. 300–700 AD) and Early Middle Ages (c. 700–1000 AD). The thesis holds that the institution of feudal monarchy developed, through contact with the Roman Empire and the Christian Church, from an earlier custom of sacral and military kingship based on both birth status and consent from subjects.
The term barbarian kingdom is used in the context of those Germanic rulers who after 476 AD and during the 6th century ruled territories formerly part of the Western Roman Empire, especially the Barbarian kings of Italy. In the same context, Germanic law is also derisively termed leges barbarorum "barbarian law" etc.
