Probus

Probus (232–282), a Pannonian soldier, rose to high command under Aurelian; Tacitus made him commander in the East. The eastern army made him emperor in 276 after Tacitus' death; his rival Florian perished at Tarsus and the Senate confirmed him.

In 277–278 he cleared Gaul of Alemanni and Franks, crossed the Rhine, rebuilt Hadrian's Rhine–Danube forts and defeated Goths and Vandals. He settled people taken from the defeated Germans in depopulated provinces and strengthened the frontier.

In 280–281 he crushed three usurpers and triumphed at Rome. In 282, preparing a Persian war at Sirmium, he was killed in a mutiny that brought Carus to power.
