Nezak Tarkhan

[2] Yazdegerd III was defeated and barely escaped with his life, but he was murdered in the vicinity of Merv soon after, and the Arabs managed to capture the city of Merv the same year.

[3] In 659, Chinese chronicles still mentioned the "Hephtalite Tarkhans" (悒達太汗 Yida Taihan, probably related to "Nezak Tarkhan"), as some of the rulers in Tokharistan who remained theoretically subjects to the Chinese Empire, and whose main city was Huolu 活路 (modern Mazār-e Sherif, Afghanistan).

[4][5] Yaqut al-Hamawi called Badghis "the headquarters of the Hephthalites" (dār mamlakat al-Hayāṭela).

This alliance expanded to include Nezak, as well as the Hepthalite princes of Transoxiania and Tukharistan.

[6] In 710, the Umayyad general Qutaiba ibn Muslim was able to re-establish Muslim control over Tokharistan and captured Nizak Tarkhan, who was executed on the orders of al-Hajjaj ibn Yusuf, despite promises of pardon, while the Yabghu was exiled to Damascus and kept there as a hostage.
