Sextus Julius Severus was an accomplished Roman General of the 2nd century AD. He also held the office of suffect consul in the last three months of 127 with L. Aemilius Juncus as his colleague.
Julius Severus was born in Colonia Claudia Aequum, today Čitluk, a small village 6 km from the town of Sinj in Dalmatian Croatia. Julius Severus served as Governor of Moesia; he was appointed Governor of Britain around 131.
In 133 he was transferred to Judea, to help suppress the Bar Kochba rebellion there. Because of his military reputation, historians have seen him as a troubleshooter, sent to troublesome provinces to bring peace through war and his presence has been taken as indication of unrest in Britain at the time. There is no archaeological evidence to suggest fighting in Britain under his governorship although a reference by the orator Fronto to many soldiers dying in Britain under Hadrian's reign may refer to trouble at this time.
