Tengri

Ride the Orkhon valley in high summer and the land gives you almost nothing. Low brown hills, a shallow river breaking over gravel, grass leaning one way and then the other. What it gives you instead is sky, unbroken from horizon to horizon, so large that it stops behaving like scenery and starts behaving like architecture. A week under it and the notion that the sky is somebody, and that the somebody is in charge, stops sounding like religion and starts sounding like a plain report of the weather.

Two blocks of stone stand in that valley, raised in 732 and 735 for a dead prince and his brother the khagan. Their opening sentence is among the oldest in any Turkic language: when the blue sky above and the brown earth below were made, between the two of them the sons of men were made. The word for that blue sky is tengri. It is also the word the same stones use for god.

That double duty is the difficulty and the point. The oldest trace of the word is older than the stones by a thousand years, sitting in a Chinese court history as a foreign term the compilers of the Book of Han thought worth explaining: the Xiongnu, they wrote, call heaven chengli and a son gutu, which is why their ruler’s full title means something like son of the boundless sky. It is the earliest attested word in any Altaic language, and it began by meaning the thing over your head. The sun is in the sky. The clouds darken the sky. Only later did that flat physical sense fall away and leave behind a god, or a vague sort of divinity, or an adjective meaning celestial, with no reliable way of telling which one a given line intends.

Worse, the inscriptions are full of other tengris. There is a Yol Tengri, god of roads or of luck, since the word yol carries both. There is an Od Tengri who governs time or weather. There is one who simply lies among the reeds, named once and never explained, and nothing in the record says how any of them stood in relation to the great sky. Meanwhile the same texts invoke far larger divine powers that are never called tengri at all, and the sun and moon, venerated as they were, never take the word either. The eleventh-century lexicographer Mahmud al-Kashgari added his own complication by noting that Turks would apply tengri to anything that struck them as enormous. A huge tree, for instance. Mountains carried it, and still do: Tengri Tag is the range the Chinese call Tian Shan. So does a lake in Mongolia.

Nobody knows what he looked like because nobody ever tried to say. There were no statues, no temple, no priesthood of his own. When the Franciscan friar William of Rubruck reached the Mongol camps in 1253 and wrote down everything he saw, he found felt figures stitched and hung above the master’s head and the mistress’s head, another lean one between them minding the house, one with a cow’s udder for the women who milked cows and one with a mare’s teat for the men who milked mares. Those were the household and the ancestors. Tengri was not among them. What Rubruck saw instead was a gesture: before anyone drank, an attendant carried a cup outside and flicked liquor three times to the south for the fire, bending the knee each time, then east for the air, then west for the water, then north for the dead, and the master tipped a little onto the ground before raising his own cup, or onto his horse’s mane if he was mounted. The sky got no idol because the sky was already there.

The stones do not say who made it. Their famous line is passive, the sky and the earth simply established, with no maker named, and the ancient cosmogonies that survive contradict each other so freely that the question of origins looks like a late arrival, pressed on the steppe by Muslim and Christian visitors who wanted to know. Where creation stories do exist in the Turco-Mongol record, the making is usually handed to someone else. In the Altai the distant lord of the sky is Tengere Kaira Khan, merciful and remote, while the actual work of world-building belongs to Bai Ulgen and his companions. Among the Yakut it belongs to the white lord creator, Iuriung Aiyy Toion, who drifted so far out of daily life that he probably never had much of a place in it.

What Tengri did, and did with terrible efficiency, was politics. He distributed kut, a heavenly vitality that made a man capable of rule, and ulug, plain luck. He named dignitaries through the khagan’s mouth and conquered through the khagan’s army. Bilge Kagan’s stone calls him heaven-like and heaven-born, and one Turk sovereign of the eighth century seems to have had no other name at all than Tengri Khan. When Chinggis Khan was raised up five centuries later it was a shaman called Teb Tenggeri, very celestial, who did the raising. One god in the sky and one lord on earth: that was the ideology, and it was a serious attempt at monotheism that never quite closed, because the older gods went on living in people’s heads regardless.

The most striking picture of the cult is not of the god but of a man alone on a hill. The sovereign climbed to high ground, uncovered his head, loosened his belt, and bowed to the sky, and he could keep at it for one day or three. White horses were killed for the same audience. Riders went round and round in a circle, a practice they called going around the sky. Souls were understood to wait in Tengri before birth and to return to him afterwards, which is why the steppe reported a death by saying that the man had flown off, or had become a gyrfalcon, or had climbed to the sky with his body.

His powers follow from that arrangement. He set the term of every life, since Tengri ordains the time and the sons of men are all born to die. He gave and revoked the mandate, and when a ruler weakened he applied pressure or sent word by an eagle, by rays of light with dazzling daughters in them, or by the wolf, who was also the ancestor. His single punishment was death, and he used it most often on rebels.

His limits follow just as neatly. He was an imperial god, and the record shows him blazing up under the Turk khaganates and the Mongol empire and going quiet in between, because ordinary people paid attention to him in proportion to how far an emperor could make them. He needed a throne to be worshipped from. Cut off from one he faded into a very distant figure with sons and assistants doing the real work, until in much of Siberia the sky held a whole crowd of unstable tengris that no one has ever managed to sort into an order. The revival that carries his name today, running in Tatarstan and Kyrgyzstan and Kazakhstan since the 1990s and lately across Turkish social media, is a modern movement with modern arguments, and scholars who have studied it read it as a tradition rebuilt for present use rather than one handed down. The eternal blue sky, it turns out, was easier to lose than to abolish.

Frequently Asked Questions

Who is Tengri?

Tengri is the sky god of the Turkic and Mongolic peoples of the Eurasian steppe, and the word is also simply the Old Turkic term for the sky itself. He is the power from whom Turk khagans and Mongol khans claimed their right to rule, and he is attested from Chinese records of the Xiongnu down to the Mongol empire of the thirteenth and fourteenth centuries.

What does the name Tengri mean?

It originally meant the physical sky, as in an ordinary sentence about clouds or the sun. After the sky was deified the word came to mean god or divine as well, and the two senses are often impossible to separate in the Old Turkic inscriptions. Turks also applied it to anything vast, including mountains, lakes and, according to the eleventh-century lexicographer Mahmud al-Kashgari, very large trees.

What did Tengri do for rulers?

He granted kut, a heavenly vitality that made a man fit to govern, along with ulug, or luck. Khagans styled themselves heaven-born, appointed officials and made war in his name, and could lose the mandate again if they weakened. His one recorded punishment was death, applied most often to those who rebelled.

Did anyone worship Tengri with statues or temples?

No. There were no images of him, no temples and no priesthood, and the felt figures the friar William of Rubruck saw in Mongol tents in 1253 represented the household and the ancestors rather than the sky god. Worship took the form of libations flicked to the four directions, sacrifices of white horses, riding in circles, and prayer offered by the ruler himself on high ground with his head bare and his belt loosened.

Is Tengrism still practised today?

A Tengrist revival has grown since the 1990s in Tatarstan, Kyrgyzstan and Kazakhstan, and more recently among Turkish social media communities, with an association in Turkey campaigning for official recognition. Researchers who have studied these movements describe them as modern reconstructions shaped by contemporary nationalism rather than an unbroken inheritance from the steppe empires.
