LW-15 Lugdunensis Senonia / Quarta

The province organized inland districts whose roads and river routes connected the Seine basin and neighbouring regions. Sens’s administrative and ecclesiastical importance emerged within a broader network of cities, agricultural estates, and local communities. The name Senonia reflected the standing of the Senonian centre, while Quarta placed it within the numbered provincial succession.
Political change in the fifth century did not occur uniformly across this inland landscape. Bishops, local elites, military leaders, and later Frankish rulers adapted existing towns and institutions. The province’s identity survived more clearly in regional and church organization than through a permanently unchanged civil administration.
