Alexandrius (Gallia Imperium)

Princeps Alexandrius (268-309) was the third and youngest son of Imperator Postumus and his wife Adela. Because he was not expected to rule, Alexander was brought up as a scholar.

He was on good relations with his brothers, as evidenced by his appointment to the consulate (288). He worked as first consul until his appointment as governor of Britannia (300). Alexander was commissioned by Augustus to buildup Hadrian's Wall (305).

Alexandrius's health deteriorated rapidly in the summer of 309. He resigned as governor and was succeeded by his eldest son, Julian (4 July 309). He succumbed to an unknown illness the following month.
