Oboi

Oboi was a prominent Manchu military commander and courtier who served in various military and administrative posts under three successive emperors of the early Qing dynasty. Born to the Guwalgiya clan, Oboi was one of four regents nominated by the Shunzhi Emperor to oversee the government during the minority of the Kangxi Emperor. Oboi reversed the benevolent policies of the Shunzhi Emperor, and vigorously pushed for clear reassertion of Manchu power over the Han Chinese. Eventually deposed and imprisoned by the new emperor for having amassed too much power, he was posthumously rehabilitated.
