Tengri- Turkic GodDeity"Kök Tengri"

The Eternal Sky

Tengri is the sky. Not a god who sits above it, but the divine power that the blue vault itself embodies. The Orkhon inscriptions, carved into stone on the Mongolian steppe in the eighth century, invoke him with the formula "Üze kök tengri," "Above, Blue Sky," a phrase that makes no distinction between the physical heavens and the supreme force governing all existence. Tengri was eternal, omniscient, and omnipotent. He did not descend to earth or take mortal form. His will manifested through the ordering of the cosmos: the turning of the seasons, the rise and fall of empires.

The word tengri reveals how deeply the concept ran. In Old Turkic it served as the name of the supreme deity, the word for sky, and a term for anything divine. Mahmud al-Kashgari, compiling his Dīwān Lughāt al-Turk in the eleventh century, noted that the Turks called God "Tengri" and applied the same word to anything vast and wondrous. A great tree could be called tengri. A great mountain likewise.

The Creation

In the dualistic creation traditions recorded among the Altai Turks by Wilhelm Radloff, Tengri and a counterpart figure, Erlik, fashion the world from primordial waters. A waterfowl dives to the bottom of the primal ocean and brings up mud, from which the earth is formed. Tengri presides above as the creative force. Erlik, envious and rebellious, introduces corruption and death into what was meant to be a perfect creation.

The two powers divided the cosmos between them. Tengri governed the sky and sent rain and healthy livestock. Erlik ruled the underworld and brought disease and misfortune. The shaman mediated between them, ascending through the sky's many layers to reach Tengri or descending to Erlik's realm depending on the community's need.

The Zhoushu (Book of Zhou, seventh century) preserves an account of Göktürk origins in which a wolf-child raised in a cave gives rise to the Turkic people under heaven's protection. Tengri is not named in every variant, but the pattern holds: the sky authorizes earthly beginnings.

Heaven and Earth

The Turkic cosmos was built on a single axis: Tengri above, the earth below. The Orkhon inscriptions invoke both together: "Üze kök tengri asra yağız yer," "Above, Blue Sky; below, the dark earth." Between these two powers, human beings were created and sustained.

The earth had its own sacred identity. Some traditions venerated it as Yer-Sub, the collective divinity of land and waterways. Others named Umay, goddess of fertility and childbirth, as the feminine counterpart to Tengri. The sacred mountain was the axis linking the two. Ötüken, the forested mountain heartland at the center of the Turkic realm, was the point where heaven's mandate touched the ground. The Orkhon inscriptions make clear that controlling Ötüken was essential to ruling the steppe. Lose Ötüken, lose the connection to Tengri.

The Divine Mandate

Tengri's most consequential act was the granting of kut: the divine mandate that empowered rulers. A khan did not rule by hereditary right alone, nor by military conquest. He ruled by Tengri's will. The kut was given and taken by heaven; a ruler who lost it would fall, no matter how strong his armies.

The Kül Tegin inscription (732 CE) states: "Tengri yarılkaduk üçün, özüm kutum bar üçün, kağan olurtum." "Because Tengri favored me, because I possessed kut, I became kağan." The same inscriptions record how Tengri withdrew his favor from the Turkic people when they abandoned their customs and submitted to the Tang Chinese, then restored it when they rose again under the Bilge Kağan.

The kut was not merely legitimacy but a kind of spiritual power. It could be transmitted within a ruling lineage but was never automatic. A khan whose campaigns failed, whose people suffered famine, was understood to have lost heaven's favor. Rulership on the steppe was perpetually conditional. Tengri watched.

The Voice in Stone

The Orkhon inscriptions of the Second Turkic Khaganate (682–744 CE) are the oldest substantial texts in any Turkic language, carved in Old Turkic runic script on stelae erected in the Orkhon Valley of central Mongolia. Tengri appears in them not as a character in a story but as the supreme authority behind historical events. The inscriptions open with a creation formula: "When the blue sky above and the dark earth below were created, between them human beings were created." Then comes history, and throughout it Tengri acts through verbs of will: he commands (buyurmış), he grants (bermiş), he favors (yarılkamış).

The Irk Bitig (Book of Omens), discovered among the Dunhuang manuscripts and dated to the ninth century, offers a different register. This divinatory text contains brief narratives and omen interpretations in Old Turkic, many referencing Tengri and Yer-Sub. Where the Orkhon inscriptions speak of empires, the Irk Bitig speaks of herds and journeys. Tengri's influence reached beyond khans. It touched ordinary lives.

The Mongol Inheritance

When the Mongol Empire rose in the thirteenth century, Tengri remained the supreme deity of the steppe. Genghis Khan attributed his conquests to Möngke Tengri, the Eternal Sky. The Secret History of the Mongols (c. 1240) opens with the statement that the ancestor Börte Chino was "born with a destiny from heaven above," echoing the cosmological formula carved into the Orkhon stelae five centuries earlier.

The Mongol great khans, like the Turkic kağans before them, ruled as Tengri's agents. Their decrees opened with the formula "Möngke Tengriin Küchündür." By the power of the Eternal Sky.
