Tiberius II Constantine, Byzantine emperor

Tiberius II Constantine was Eastern Roman emperor from 574 to 582. Tiberius rose to power in 574 when Justin II, prior to a mental breakdown, proclaimed him caesar and adopted him as his own son. In 578, the dying Justin II gave him the title of augustus, thus becoming co-emperor alongside him. Tiberius became sole ruler less than two weeks later, assuming the regnal name of "Constantine" under which he reigned until his death.

August 14 is the 226th day of the year in the Gregorian calendar; 139 days remain until the end of the year.
