Reform of Diocletian (around 300)
Emperor Diocletian restructured the provinces around 300, and split Belgica into two provinces: Belgica Prima and Belgica Secunda. Belgica Prima had Augusta Treverorum (Trier) as its main city, and consisted of the eastern part. The border between Belgica Prima and Belgica Secunda was approximately along the Meuse.
