Tiberius II Constantine
Tiberius II Constantine (c. 535–582), a Thracian commander of the Excubitor guard, was the trusted friend of Justin II. Justin adopted him and named him Caesar in 574 during his madness.
Tiberius governed with Empress Sophia, and in September 578 the dying Justin crowned him Augustus before his death on 4 October. A generous ruler, he gave away thousands of pounds of gold and ended Monophysite persecution.
His general Maurice raided into Persia, but in 582 the Avars seized Sirmium and Slavs overran the Balkans. Dying, Tiberius made Maurice co-emperor on 13 August 582 and died the next day.
