Britannia Inferior

Britannia Inferior (Latin for “Lower Britain”) was a new province carved out of Roman Britain probably around AD 197 during the reforms of Septimius Severus although the division may have occurred later, between 211 and 220, under Caracalla. The removal of the governors in Londinium from control over the legions guarding Hadrian’s Wall was aimed at reducing their power, given Clodius Albinus’s recent bid to become emperor. The province was probably formalised around 214 by Severus’s son Caracalla.
