Taksi

Taksi (Manchu: ; ; 1543–1583), or posthumously titled as Emperor Xuan, was a Jurchen chieftain and father of Nurhaci, founder of the Later Jin dynasty, and the fourth son of Giocangga. A member of the House of Aisin-Gioro, he was killed in an attack on Gure (古哷 Gǔlè) by a rival Jurchen chieftain Nikan Wailan in 1583.

Taksi had nine recorded children. Nurhaci was the first born son and also the most highly achieved. It seems like several of Nurhaci's brothers had names that closely resembled his phonetically.

The Seven Grievances issued by Nurhaci claimed that the Ming dynasty killed Taksi for no reason. This caused Nurhaci to declare war on the Ming, which eventually led to the destruction of the Ming and rise of the Qing dynasty.

During the reign of the Shunzhi Emperor, the court of the Qing dynasty retroactively gave Taksi the temple name Xianzu (顯祖) and the posthumous name Emperor Xuan (宣皇帝).
