Böri Shad

Böri Shad (Old Turkic: , böri šad, simplified Chinese: 步利设; traditional Chinese: 步利設; pinyin: bùlì shè; Wade–Giles: pu-li she, "Wolf governor") was a title of an appointed head of province-type principality in the most-western North Caucasus periphery of the Western Turkic Kaganate. Within the lateral succession order of the kaganate, members of the ruling clan were successively given possessions in accordance with their rank in respect to the ruling Kagan. Accordingly, a succession of princes, or shads, occupied that position. The principality of Böri Shad originated in 558 CE, when Kara-Churin (later named Tardu or Tardush), a brother of the ruling kagan, campaigned in Ural and Volga regions, but the lands he captured were given to his junior brother Turksanf and his cousin Buri-khan. From 576 through 583 CE Tardu, fought with Byzantine, but instead of himself, he appointed a head of the campaign his cousin Böri Shad, whose possessions were in the N. Caucasus.

According to Movses Kagankatvatsi, Böri Shad was a 7th-century Göktürk prince and an ishad or general in the army of the Western Turkic Khaganate. He was the son of Bagha Shad, who may have been the yabgu or prince of the Khazars. Böri Shad's uncle was Tong Yabghu Khagan, the khagan of the Western Göktürks.
