Nurhaci (1559–1626), khan of the Jurchens, founded the Later Jin dynasty in 1616 in reference to the Jurchen-led Jin dynasty (1115–1234) that had once reigned over north China. His son and successor Hong Taiji (1592–1643) renamed his people "Manchu" in 1635 and changed the name of Nurhaci's state from "Great Jin" to "Great Qing" in 1636. Hong Taiji was the real founder of Qing imperial institutions. He was the first to adopt the title of "emperor" ("huangdi") and founded an Imperial Ancestral Temple in the Qing capital Mukden in 1636. After the Qing captured Beijing in 1644 and appropriated the Ming Ancestral Temple, from 1648 on, Nurhaci was worshiped there as Qing "Taizu", a temple name reserved for dynastic founders.
