Baoyi Qaghan or Alp Bilge Qaghan was the eighth ruler of Uyghurs. His personal name is not known, therefore he is often referred to as his Tang dynasty invested title Baoyi which was invested on 22 June 808.[1]
He was known as a zealous Manichean ruler and militarily active ruler. He demanded a Chinese Princess from Xianzong of Tang by sending his minister Inanchu Külüg Chigshi on 24 June 810, a request that was refused. Xianzong's reason was the expenses involved. Xianzong asked Manichean priests to pursue Baoyi and drop the request. Baoyi used this opportunity to occupy Tiquan (鵜泉) in April 813. Xianzong's Minister of Rites Li Jiang suspected that Baoyi would make peace with the Tibetan Empire in order to invade China. He suggested that Baoyi's proposal to marry a Tang princess should be accepted, to further affirm the alliance between Tang and Uyghurs. His suggestion, however, was not accepted.[2]
His request was only realized when he sent Ulu Tarkhan (Hedagan 合達干) to Emperor Muzong, who married off his sister Princess Yong'an (永安公主) in 821. However, the qaghan soon died after marriage.[3] He was succeeded by his son Chongde Qaghan.
He had at least 4 sons:
He is famous for commission of trilingual (Chinese, Old Turkic, Sogdian) Karabalgasun inscription in Ordu-Baliq.[4]
