Quyurchuq (Qūyūrčuq) [1] was the khan of the Golden Horde in 1395–1397, appointed by Timur (Tamerlane). Information on his life and reign is very limited.
According to the Muʿizz al-ansāb and Tawārīḫ-i guzīdah-i nuṣrat-nāmah, Quyurchuq was a son of Urus Khan, a descendant of Tuqa-Timur, the son of Jochi, the son of Chinggis Khan. They give the ancestry as Qūyūrčuq, son of Urus Khān, the son of Bādāq, the son of Tīmūr-Khwāja, the son of Tāqtaq, the son of Achiq, the son of Ūrungbāsh (Ūrūng-Tīmūr), the son of Tūqā-Tīmūr, the son of Jūjī.[2]
A younger son of Urus Khan, Quyurchuq survived his family's loss of the throne of the left (east) wing of the Golden Horde, the former Ulus of Orda, in 1379. In unclear circumstances he made his way to the court of Timur (Tamerlane), and became one of his captains. Quyurchuq accompanied Timur's second expedition into the Golden Horde, in 1395–1396, and participated in the Battle on the Terek in April 1395. Following the battle, Timur gave Quyurchuq a force of "Uzbek braves," set out for him the regalia of a khan, gave him a gold-embroidered caftan and gold belt, and ordered him to cross the Volga and take over the Golden Horde.[3]
Quyurchuq did as instructed, and was successfully installed as khan at the traditional capital, Sarai. However, it would be a short and unhappy reign. The core territory of the Golden Horde had been plundered and ravaged by Timur, and the main cities, Sarai included, had been pillaged and razed. Timur headed home in the spring of 1396, leaving Quyurchuq in a difficult position at Sarai. The defeated khan Tokhtamysh was still at large in the north and west, while two relics of Timur's previous invasion of the Golden Horde, the rival khan Tīmūr Qutluq and his uncle Edigu controlled the territory to the east. While Tokhtamysh set out to reassert his authority over the southwestern portions of the Golden Horde, Tīmūr Qutluq and Edigu attacked and defeated Quyurchuq, seizing Sarai. This is generally dated to 1397, although it could have happened as early as 1396, immediately after Timur's departure. According to Tatar folklore, Quyurchuq was killed by Edigu himself.[4]
According to the Muʿizz al-ansāb, Quyurchuq had a son and two daughters, three grandsons and a granddaughter, as follows.[5]
