Sukhra in the context of "Hephthalite Empire"

Kavad I (Middle Persian: 𐭪𐭥𐭠𐭲 Kawād; 473 – 13 September 531) was the Sasanian King of Kings of Iran from 488 to 531, including a two or three-year interruption. A son of Peroz I (r. 459–484), he was crowned by the nobles to replace his deposed and unpopular uncle Balash (r. 484–488).

Inheriting a declining empire where the authority and status of the Sasanian kings had largely weakened, Kavad tried to reorganize his empire by introducing many reforms whose implementation was completed by his son and successor, Khosrow I. They were made possible by Kavad's use of the Mazdakite preacher Mazdak, leading to a social revolution that weakened the authority of the nobility and the clergy. Because of this, and the execution of the powerful king-maker Sukhra, Kavad was deposed and imprisoned in the Castle of Oblivion. He was replaced by his brother Jamasp. However, with the aid of his sister and an officer named Siyawush, Kavad and some of his followers fled east to the territory of the Hephthalite king, who provided him with an army. This enabled Kavad to restore himself to the throne in 498/9.

The Qarinvand dynasty (also spelled Karenvand and Qarenvand), or simply the Karenids, was an Iranian dynasty that ruled in parts of Tabaristan (Mazandaran) in northern Iran from the 550s until the 11th century. They considered themselves as the inheritors of the Dabuyid dynasty, and were known by their titles of Gilgilan and Ispahbadh. They were descended from Sukhra, a Parthian nobleman from the House of Karen, who was the de facto ruler of the Sasanian Empire from 484 to 493. The Qarinvand dynasty is also considered to be one of the last Zoroastrian dynasties before the rise of the Islamic Iranian dynasties

Zarmihr Karen (died 558) was an Iranian nobleman from the House of Karen, who served as the Sasanian governor of Zabulistan. He was the son of Sukhra.
