Caesar 574 - 578, Augustus 578 - 582

Co-emperor: Justin II, 565 - 578

As the emperor Justin II became increasngly mentally ill, it became apparent that a regent was needed to handle matters of state. The Count of the Excubitors, Tiberius, was appointed Caesar in 574, and nine days before the death of Justin in October 578, was raised to the rank of Augustus. A popular and generally effective emperor, Tiberius gained the fondness of his subjects through his liberality and generosity. Before he died, he named his successor as Count of the Excubitors, Maurice, as his imperial successor.
