Year 774 (DCCLXXIV) was a common year starting on Saturday (link will display the full calendar) of the Julian calendar. The denomination 774 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.
- Battle of Berzitia: The Bulgarian ruler (khagan) Telerig sends a small raiding army (12,000 men) to strike into the southwest of Macedonia and capture Berzitia. Emperor Constantine V is informed for this raid by his spies in Pliska, and assembles an enormous force (80,000 men). He surprises the Bulgarians who did not expect to find a Byzantine army there, and defeats them with heavy losses.
- Telerig sends a message to Constantine V, stating that he is going to flee in exile to Constantinople. In exchange, he ask the emperor to reveal the spies to his associates in Pliska for their own safety. Constantine sends the Bulgarian government a list of the spies, however Telerig executes them all and eliminates the Byzantine spy network within his government.
