774 CE
Telerig, although he is first mentioned in the Byzantine sources only in 774, is considered the immediate successor of Pagan, who was murdered in 768.
Constantine V embarks on a major expedition against Bulgaria in May 774, leading his field army on land, and dispatching a fleet of two thousand ships carrying horsemen towards the Danube delta.
The fleet disembarks in the vicinity of Varna, but the emperor does not press his potential advantage and inexplicably retreats.
Shortly afterwards the two sides sign a truce promising the cessation of hostilities.
However, in October 774 Telerig sends an army of twelve thousand men to raid Berzitia, Macedonia and to transfer its population to Bulgaria.
Collecting a large army of eighty thousand troops, Constantine V surprises the Bulgarians and wins a resounding victory.
The subsequent attack on Bulgaria fails, because the imperial fleet encounters contrary winds in the Black Sea.
At this point Telerig sends a secret emissary to Constantine V, indicating his intention to flee Bulgaria and seek refuge with the emperor, and seeking assurances of hospitality and a list of people of the Empire who might help him.
Telerig succeeds in having the emperor betray his own agents in Bulgaria, who are duly rounded up and executed.
