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. 700–1,000 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.
