The Tariat inscriptions appear on a stele found near the Hoid Terhyin River in Doloon Mod district, Arkhangai Province, modern-day Mongolia (the forms Terkhin and Terhyin are also used). The stele was erected by Bayanchur Khan of the Uyghur Khaganate in the middle of the eighth century (between 753 and 760 CE seems to be the best estimate).
