The Turkic War of Independence is the name given to the six years in which the Ashina under Bumin broke the overlordship of the Rouran and made the First Göktürk Khaganate. It dates from 546 and not earlier. The raid of 542 on the Western Wei frontier was one of the raids the Göktürks made there every winter.^[1] The war began with the break of 546. Bumin intercepted the Tiele rising and asked Anagui for a princess. Anagui called him a blacksmith slave, and Bumin killed the envoy who brought the answer. The war ended in the spring of 552 with two battles, the death of the Rouran khan and Bumin’s entry into Ötüken. The dating rests on inference. The sequence of events rests on the sources.

Sources

The war is known almost entirely from the Göktürk chapter of the Zhou Shu and from the later compilations that draw on it. The work was compiled in 636 for a Chinese state whose predecessor had been Bumin’s ally. The raid of 542 appears in a separate biography in the same work. The Zizhi tongjian supplies what chronology there is. No Rouran voice survives. The Göktürks’ own account is in the Kül Tegin inscription, two centuries later.^[2] The inscription says only three things. Bumin and Istemi sat on the throne and held the realm and the law of the Göktürk people. The four quarters were enemies. They made them all submit.^[2] The Zhou Shu names Bumin alone as the leader of the war. What Istemi did in these years is not recorded.

Background

The Ashina were one Turkic group among several under Rouran overlordship. They were obliged to render service and, if the metalworking association is taken at face value, goods. They lived in the Altai, far from the Rouran centre in the Orkhon country. Their routes ran west toward the Tiele and south toward the Chinese frontier. Bumin took hold of the tribe about 542, on the death of his father. From that year the Ashina act on their own account. There followed the raid of 542, the reception of the Western Wei embassy of 545 and the return embassy of 546. Then came the intervention against the Tiele. The sequence is consistent throughout with a deliberate loosening of the Rouran connection rather than with a series of improvisations.

The situation was unusually favourable. Northern China was divided between the Western Wei and the Northern Qi. Each had reason to seek allies against the other and against the Rouran. The Rouran under Anagui had held the steppe for decades. Relations with the Hephthalites had cooled, however. When his subjects became restive, Anagui had no external counterweight. The Tiele were preparing a further revolt. Some modern accounts add the climate. The extreme years of 536–545 had weakened everyone, and the war’s six-year length is seen as a consequence of them. Palaeoclimatologists put figures to those years. They find eruptions in 536, 540 and 547, and the coldest decade of two thousand years from 536 to 545. In the Altai, the 540s were the coldest decade of all, 3.2 degrees below the modern mean. Turkic Atlas sets out the debate under climate and the steppe empires.

Outbreak (546)

In 546 the Tiele moved against the Rouran.^[3] Bumin intercepted them on the march and defeated them. More than fifty thousand submitted to him. The engagement has its own article.^[3] In return for this, Bumin sent to Anagui to ask for a Rouran princess. The Zhou Shu records the refusal in direct speech. Anagui called him his blacksmith slave and asked how he dared speak so.^[3] Bumin killed the envoy who brought the answer. He broke off relations.^[3]

Marriage into the ruling house would have given Bumin a claim on the Rouran succession. This is the usual explanation for both the request and the vehemence of the refusal. Killing an envoy could not be taken back. Whatever the request had been meant to achieve, the response closed the matter and made war inevitable. From this moment there was a front between the family of smiths and the empire that had ruled the steppe for a hundred and fifty years. It could not be talked away.

Preparations (547–551)

The sources say nothing for four years. Bumin spent them assembling support among other Turkic groups. This is an inference from the size of the force he commanded in 552. How that support was obtained, and which groups joined, is not recorded. The six years between the break and the war read as a time of preparation. In them Bumin rallied the Tiele federation, allegedly forty tribes, and other Turkic groups not previously involved. He financed the war with the trade in iron and ironware that the Ashina had always worked. For his part, Anagui fortified his capital at Mumocheng with a double wall. He kept an elite guard there.

In 551 Bumin married a princess of the Western Wei ruling house, named in the Zhou Shu as Changle.^[3] Yuwen Tai secured the alliance. He knew that Bumin had broken with his overlord, and he knew which was the smaller party. He gave the princess anyway, because a Göktürk at the Rouran’s back was worth more to him than a Rouran at peace.^[3] One account adds that the Wei allowed Göktürk troops passage through their territory during the war. It also reports a Korean claim that ten thousand Göktürks appeared on the frontier of Koguryŏ in 551 and besieged several towns.

Two battles of 552

By the beginning of 552 the Ashina and the Rouran were in a state of undeclared war. The conflict escalated early in the year with two engagements. In January a Rouran force sent west was beaten in Dzungaria.^[4] A second and larger army met the Göktürks as they turned east toward the capital. It was destroyed north of Huaihuang in the first month of the Chinese year.^[3] That month ran from 11 February to 10 March 552. The Chinese histories record only this second battle. Bumin marched on Mumocheng. According to the Chinese account, Anagui took his own life, either before or after Bumin’s arrival. The doubt raised against the suicide is set out in his article.^[3] The Rouran nobility, including the khan’s sons, scattered. Part went south into the Northern Qi and part west across the steppe.^[3]

That was the whole war. After two battles in the space of a season, an army that had held the steppe for a century and a half no longer existed.

Taking of Ötüken (April 552)

Bumin entered Ötüken, the old sacred centre of the steppe. He assumed the title Illig Khan.^[3] He did not take Mumocheng, and he did not dismantle the Rouran state. The structures of the khaganate passed to him largely intact, with a different ruling lineage at the head. He died within the year. The finishing of the Rouran remnant, in China and on the Ordos, fell to his sons in the later Göktürk–Rouran Wars.^[3]

Assessment

It was a war of liberation and a revolution. From the spring in which Anagui died date the seven centuries of Turkic rule over the steppe. Both statements are valuations, not findings.^[5] What the sources show without valuation is a subject people that had rendered iron and obedience for a hundred years. They show a leader who spent four years turning a refused marriage into an army. They show an empire that fell in a season to the smallest of its subjects. The Göktürks’ own memory of it, carved in 732, does not mention the Rouran at all.^[2]
