[1] 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.
[2][note 1] Senecio Albinus’ career under the Severan Dynasty was remarkable, given his relationship to 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).
In around 208 or 209, he was appointed the electus ab Augustis ad cognoscendum vice sacra (the officer presiding over judicial cases in place of the emperor), when Severus and his sons were on campaign.
[3] Possibly between 209 and 212, Senecio Albinus was the Legatus Augusti pro praetore of the province of Hispania Tarraconensis.
