Krum the Fearsome

Krum introduced a set of laws aimed at centralizing power and unifying the Bulgarian state. These laws included measures against theft, drunkenness, and false oaths, and established a uniform legal system.

Krum led the Bulgarian army to a decisive victory over the Byzantine Empire at the Battle of Pliska. Byzantine Emperor Nikephoros I was killed in the battle, and his skull was later used as a drinking cup by Krum.

Krum besieged Constantinople after a series of victories over the Byzantines. He failed to capture the city due to its strong defenses and the death of Krum shortly after, but the siege demonstrated Bulgarian military power.
