How a family succession dispute shattered the vast Göktürk Empire from within
The Göktürk civil war, spanning 583 to 603, fractured a massive empire that once stretched from Manchuria to the Black Sea. Triggered by a contested succession following the death of Taspar Qaghan, the conflict pitted rival Ashina clan members against each other, ultimately forcing the khaganate into permanent division.
The Turkic Khaganate operated under a system where the kurultay, a council of tribal leaders, appointed khagans from the ruling Ashina family. When the fourth khagan, Taspar Qaghan, died in 581, he left behind a power vacuum with four distinct claimants: his son Anluo, his nephews Apa and Ishbara, and his cousin Tardu. Although Taspar had expressed a preference for Apa, the kurultay initially favored Anluo. This decision was quickly overturned by Ishbara, who leveraged his influence to seize the title for himself, setting the stage for two decades of internal strife.
By 584, the conflict turned violent. Ishbara Qaghan raided Apa Qaghan’s territory, killing his mother and forcing him to flee to the west. Apa sought refuge with Tardu, who controlled the western reaches of the empire. This alliance, bolstered by Tardu’s brother Tamgan, proved so formidable that Ishbara was forced to accept the suzerainty of the Sui dynasty to survive. The shifting loyalties were driven by strategic interests, particularly control over the lucrative Silk Road. When Apa eventually settled near Bukhara, his alliance with Tardu collapsed due to these very disagreements, leaving the empire perpetually unstable.
The civil war effectively ended the unified rule of the Ashina dynasty. While Ishbara and his successors, Bagha and Tulan, held the east, Tardu maintained control of the west. Though Tardu briefly reunified the two halves after Tulan’s death, the split became permanent after 603. The empire’s fragility eventually invited conquest by the Tang dynasty, which subjugated the Eastern Khaganate in 630 and the Western Khaganate in 657. It was not until 682 that the Göktürks regained their independence under Ilterish Qaghan, marking the establishment of the Second Turkic Khaganate after decades of foreign dominance and failed restoration attempts.
