George I Terter of Bulgaria

George Terter I (died 1308 or 1309), a Bulgarian boyar of Cuman descent, was tsar from 1280 to 1292. Ivan Asen III made him despot and he divorced his wife to marry the emperor's sister; his first wife and their son Theodore Svetoslav were sent as hostages to Byzantium.

When Ivan Asen fled in 1280, George seized the throne, but Mongol raids under Nogai Khan weakened his rule. After Nogai attacked Bulgaria around 1292, George was deposed and went into exile in Byzantium, where he lived in want.

In 1301 his son Theodore Svetoslav, now tsar, ransomed him for thirteen captured Byzantine officers. George ended his days in Bulgaria.
