The Uyghur Empire

Introduction

The Uyghur Empire (744-840) succeeded the Göktürks as the dominant power in the Central Asian steppes. This empire distinguished itself through its adoption of Manichaeism and the development of a sophisticated written culture that had lasting influence on Turkic and Mongol civilizations.

Foundation and Expansion

In 744, the Uyghurs overthrew the Second Göktürk Empire and established their own khaganate. Their capital, Ordu-Baliq (Karabalgasun), became a prosperous urban center in the Orkhon Valley, a rarity for a nomadic empire.

At its peak, the empire controlled a vast territory from Manchuria to Central Asia and maintained close relations with Tang China.

The Religious Turn

The most significant event was the official conversion to Manichaeism in 762, after the khagan's encounter with Manichaean missionaries during a campaign in China. The Uyghurs thus became protectors of this persecuted religion.

This conversion had profound consequences: development of writing, construction of temples, and transformation of cultural practices. It was the first time a nomadic steppe empire officially adopted a written religion.

The Uyghur Alphabet

The Uyghurs adapted the Sogdian alphabet to write their language, creating the Uyghur alphabet. This writing system was later adopted by the Mongols and Manchus, perpetuating its influence for centuries.

Fall and Legacy

The empire collapsed in 840 under pressure from the Yenisei Kirghiz. The Uyghurs migrated south, establishing kingdoms in the Tarim Basin and at Ganzhou.

Their cultural legacy endured: their alphabet, religious and administrative practices profoundly influenced the Mongol Empire and later Chinese dynasties.
