Vetranio in Wikipedia
Vetranio (d. c. 360), born in the province of Moesia in a part
of the region located in modern Serbia, is sometimes but
apparently incorrectly referred to as Vetriano. He was an
experienced soldier and officer when he was asked by
Constantina, the sister of Roman Emperor Constantius II, to
proclaim himself Caesar (March 1, 350). Her brother Constans
had been killed by Magnentius earlier that year and she
probably thought Vetranio could protect her family and herself
against the usurper. Vetranio accepted and coins were minted
in his name, showing the title of Augustus (full emperor),
rather than Caesar. Constantius first seemed to accept the new
Emperor and sent him money to raise an army, as well as his
Constantius, who was on a campaign against the Persians when
Magnentius came to power, returned to the west and met with
Vetranio. Vetranio subsequently abdicated on December 25, 350.
He was allowed to live the remainder of his years as a private
citizen on a state pension.
