Uighur -Chinese Relations            

      
        In the year of 759, he was replaced by Bögü Kağan (759-779) (Tanrıda bolmuş il tutmuş Alp Külüg Bilge Kagan= endowed with State by the God). He had also paid great attention to China where some civil turmoil and conflicts went on. His main purpose was to establish domination in China where the T'ang dynasty was not so influential any more. Upon the appearance of Uighur army in China (762), the Chinese commander P'u-ku (Buku, a Turkish title) Hua-ien, a commander of Töles origin who had been a relative of the ruler annihilated the renegades and the advance of the Uighur people were prevented thereof. However, the Turkish influence had increased in China to an extreme degree.

 

        There were numerous Uighur people who performed free trade in the capital city and the other cities. These Uighur people would purchase silken fabrics with any amount that they desired and sell them with any price that they determined. Upon the invitation of P'u-ku Huai-en in order to protect China from the Tibetan attacks, Bögü organised a military expedition to Lo-yang (763). This military expedition had ended up with important results in respect of the Turkish cultural history. In the way of return of the Ruler to Ötüken, he took four priests with him in order to diffuse the religion Manichaeism among the Turks.

 

        This religion would have enormous effects in respect of the change of lifestyles and world conceptions of the Uighur people. Manichaeism was a religion that resulted from the combination of Christianity-Mazdaism- Buddhism that prohibited eating animal products and attenuated the warrior spirits of the people. Therefore, Manichaeism was adopted by the ruler and it attained an official character within the Turkish country.
