ガリア・ベルギカ
Roman government was run by Concilia in Reims or Trier. Additionally, local notables from Gallia Belgica were required to participate in a festival in Lugdunum (modern Lyon) which typically celebrated or worshiped the emperor’s genius. The gradual adoption of Romanized names by local elites and the Romanization of laws under local authority demonstrate the effectiveness of this concilium Galliarum. With that said, the concept and community of Gallia Belgica did not predate the Roman province, but developed from it.
