Marcus Nummius Umbrius Primus Senecio Albinus

Marcus Nummius Umbrius Primus Senecio Albinus (fl. late 2nd century to early 3rd century AD) was a Roman senator who was appointed consul in AD 206.

Senecio Albinus probably originally came from the town of Beneventum in Southern Italy, where, due to his building activities in the town, he was recognized as the civis patronus (or patron) of the town. The family also had estates in and around Brixia.

It has been traditionally held that Senecio Albinus was the biological son of Nummius Albinus, a half brother of the Roman emperor Didius Julianus, who was probably condemned to death by Septimius Severus in 193 when Severus overthrew Julianus. At some point, Senecio Albinus was adopted by Marcus Umbrius Primus, a member of the Umbrii Primi from Compsa (today Conza della Campania), which had very close ties to Beneventum.

Senecio Albinus’ career under the Severan Dynasty was remarkable, given his relationship to the deposed and murdered Didius Julianus. Possibly of Patrician status, he began his career as a Triumvir Monetalis before gaining some military experience as Sevir equitum Romanorum turmae primae (or commander of the first cavalry unit). This was followed by his posting as curator of Carthage. Then in around AD 199, he was an imperial candidate of Septimius Severus for the position of Quaestor. Next, he was a legatus proconsulis in Asia before fulfilling in the same role in Africa in around AD 202, either under his adopted father Marcus Umbrius Primus (who was the proconsular governor), or just after his father had left.
