The Bilge Qaghan Inscription: The Eternal Stone of the Turkic Empire

The Bilge Qaghan Inscription (or Bilge Kağan Yazıtı) is one of the most critical historical documents of the Turkic world. Erected in 735 AD, it is a massive stone stele dedicated to the fourth Qaghan of the Second Turkic Khaganate. Along with the inscription of his brother, Kul Tigin, it forms the famous "Orkhon Inscriptions," which are the oldest known examples of a Turkic language written in a native script.

The monument was commissioned by Bilge Qaghan’s son and was inscribed by his nephew, Yollıg Tigin, over a period of 34 days.

Historical and Cultural Significance

The inscription is not merely a memorial; it is a political testament and a message of survival addressed to the Turkic people. It was written at a time when the empire was struggling against the influence of the Tang Dynasty.

• A Warning to the Nation: The text famously contains Bilge Qaghan’s stern warnings to his people. He cautions them against the "sweet words and soft silks" of the Chinese, which he believed led to the loss of Turkic independence and the assimilation of their culture.

• The Narrative of Unity: The Qaghan recounts how he and his brother, Kul Tigin, took an empire that was "dying and exhausted" and made it "great and rich." He describes his military campaigns that reached the Iron Gate in the west and the Shantung plain in the east.

• The Orkhon Script: The steles provide the primary evidence for the Old Turkic runic script. This unique alphabet was specifically designed to be carved into hard surfaces like stone and wood, moving from right to left.

Visual and Architectural Features

The monument originally stood within a large sacrificial complex that included a temple, a canal, and various statues.

• The Stele: The stone stands roughly 3.45 meters high and features inscriptions on all four sides. Three sides are written in Old Turkic runes, while one side features a Chinese inscription, reflecting the diplomatic and cultural overlap of the era.

• The Symbols: At the top of the stone, there is a carved ibex—the royal seal (tamga) of the Ashina clan—and two intertwined dragons, symbolizing power and the heavenly origin of the Khagan.

• The Foundation: Like many monuments of this era, it was originally mounted on the back of a massive granite stone turtle (Bixi), representing the unshakeable and eternal nature of the state.

Preservation

While a replica stands at the original site in the Khashaat soum, the authentic 8th-century stone is now safely housed inside the Museum of Khushuu Tsaidam to protect its delicate carvings from the harsh Mongolian climate.
