Taspar Qaghan

Taspar Qaghan or Tatpar Qaghan (Old Turkic: , Tatpar qaγan, 佗缽可汗/佗钵可汗, Pinyin: tuóbō kěhàn, Wade-Giles: t'o-po k'o-han) was the third son of Bumin Qaghan and Wei Changle (長樂公主), and the fourth khagan of the Turkic Khaganate (572–581). Unlike his father and older brothers he embraced Chinese culture, especially Buddhism. He was converted to Buddhism by the Qi monk Huilin, for whom he built a pagoda. Taspar's death marked the beginning of a long decline and subjugation of the Göktürks to China.

The third son of Tumen and fourth qaghan. He switched his alliance from Zhou to Qi and granted defeated Qi prince asylum. He attacked Zhou repeatedly until they bought his goodwill with princess Zhou Tsienkien, whom they traded for the head of the Qi prince.

During his reign there was a veitable flood of Sogdian Manichiean refugees from Persia and Buddhist Refugees from Qi and Zhou. Both the result of pogroms. These Sogdians devised the Göktürk Runes to write the Turkic language, for translations of the sutras to Turkic. Notably the Nirvana Sutra.
