Valens (328 – 9 August 378), fully Flavius Julius Valens Augustus (Latin:FLAVIVS IVLIVS VALENS AVGVSTVS), was Eastern Roman Emperor from 364 to 378. He was given the eastern half of the empire by his brother Valentinian I after the latter's accession to the throne. Valens, sometimes known as the Last True Roman, was defeated and killed in the Battle of Adrianople, which marked the beginning of the collapse of the decaying Western Roman Empire.
