The reign of George Terter I represents a continuation of Bulgaria's precipitous decline during the second half of the 13th century. Although George Terter I managed to maintain himself on the throne for more than a decade (unlike his two immediate predecessors), he appears to have failed to assert himself against the centrifugal forces even in his own capital. This severely limited any possibility of engaging in grand-scale international politics or even standing up to foreign aggression and Mongol raids. During the chaotic years preceding George Terter I's accession Bulgaria had lost all of Thrace to the Byzantine Empire, and under his reign its remaining possessions in Macedonia were divided between the Serbians and the Byzantines in 1282–1284.
The antecedents of George Terter I are unclear, but the Byzantine sources testify that he was of Bulgarian and Cuman descent, something corroborated by his double name, which recalls the name of the Cuman clan Terteroba. George Terter I had at least one brother, named Aldimir (Eltimir), who was made a despotēs by either his older brother or by the regency for Ivan II.
When Ivan Asen III became emperor at Tărnovo in 1279 during the Uprising of Ivaylo, he sought to strengthen his position by allying himself with George Terter. The latter divorced his first wife Maria, who was sent together with their son Theodore Svetoslav as a hostage to the Byzantine Empire, to marry Maria (Kira Maria), the sister of Ivan Asen III. George Terter was accordingly made a despotēs, the highest rank in the Byzantino-Bulgarian court hierarchy.
The continued success of Ivaylo against Byzantine reinforcements led Ivan Asen III to flee the capital and escape to the Byzantine Empire, while George Terter I seized power as emperor in 1280. With the threat from Ivaylo and Ivan Asen III removed, George Terter I made an alliance with King Charles I of Sicily, with Stefan Dragutin of Serbia, and with Thessaly against Michael VIII Palaiologos of the Byzantine Empire in 1281. The alliance failed as Charles was distracted by the Sicilian Vespers and the secession of Sicily in 1282, while Bulgaria was ravaged by the Mongols of the Golden Horde under Nogai Khan. Seeking Serbian support, George Terter I engaged his daughter Anna to the Serbian king Stefan Uroš II Milutin in 1284.
Since the death of the Byzantine Emperor Michael VIII Palaiologos in 1282, George Terter I re-opened negotiations with the Byzantine Empire and sought the return of his first wife. This was eventually accomplished by treaty, and the two Marias exchanged places as empress and hostage. Theodore Svetoslav also returned to Bulgaria after a successful mission of Patriarch Joachim III and was made co-emperor by his father, but after another Mongol invasion in 1285, he was sent off as a hostage to Nogai Khan. Theodore Svetoslav's other sister, Helena, was also sent to the Horde, where she married Nogai's son Chaka.
For unknown reasons, though possibly under Mongol pressure, George Terter I sought refuge in the Byzantine Empire in 1292. The Byzantine Emperor Andronikos II Palaiologos at first refused to receive him, perhaps fearing complications with the Mongols, and George Terter was kept waiting in wretched conditions in the vicinity of Adrianople. The former Bulgarian emperor was eventually sent to live in Anatolia. George Terter I passed the next decade of his life in obscurity. In 1301 his son Theodore Svetoslav, already emperor of Bulgaria, defeated a Byzantine army and captured thirteen high-ranking officers, whom he exchanged for his father.
In Bulgaria George Terter I was not associated in power by his son, but he was confined to luxurious life in a city chosen by his son. An inscription from a rock-cut church near Ivanovo laconically mentions the death of "emperor Gergi" in the year 1308/1309.
George Terter I was married twice. By his first wife, a Bulgarian named Maria, he had two children:
