What is "jirgalang"

Jirgalang or Jirhalang ( Manchu: 1599 – June 11, 1655) was a Manchu noble, regent, and political and military leader of the early Qing dynasty. Born in the Aisin Gioro clan, he was the sixth son of Šurhaci, a younger brother of Nurhaci, the founder of the Qing dynasty. From 1638 to 1643, he took part in many military campaigns that helped bring down the fall of the Ming dynasty. After the death of Huangtaiji (Nurhaci's successor) in September 1643, Jirgalang became one of the young Shunzhi Emperor's two co-regents, but he soon yielded most political power to co-regent Dorgon in October 1644. Dorgon eventually purged him of his regent title in 1647. After Dorgon died in 1650, Jirgalang led an effort to clean the government of Dorgon's supporters. Jirgalang was one of ten " princes of the first rank" whose descendants were made "iron-cap" princes , who had the right to transmit their princely titles to their direct male descendants perpetually.
