Goths on the
Danube elect
Marcus Aemilius Aemilianus as new emperor. He advances on
Rome along the
Flaminian Way, to meet his opponent emperor
Trebonianus Gallus and his son
Volusianus. For the most part, generals in the border regions are proclaimed
emperor by their armies to halt the invasion of
Germanic tribes. • Aemilianus is proclaimed "enemy of the State" by the
Roman Senate. Trebonianus Gallus is defeated at
Interamna Nahars (
Umbria); he flees with Volusianus to the north, but at
Foligno they are killed by their own troops. • Aemilianus rules the Roman Empire for three months; he promises to fight in
Thrace and goes to war against
Persia. The Senate gives him the rank of
Pontifex Maximus. • Aemilianus is murdered at
Spoletium and
Publius Valerianus, age 60, is recognised as the new emperor by the
Rhine legions. He gives his son
Publius Licinius Egnatius Gallienus the title
Augustus. Valerianus I dispatches him to the Danube where the Goths have violated the treaty signed with Rome and invaded
Moesia. • Valerianus I splits the Roman Empire in two; Gallienus taking control of the West and his father ruling the East, where he faces the
Persian threat. •
