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.

The Kangxi Emperor, also known by his temple name Emperor Shengzu of Qing, personal name Xuanye, was the third emperor of the Qing dynasty, and the second Qing emperor to rule over China proper. His reign of 61 years makes him the longest-reigning emperor in Chinese history and one of the longest-reigning rulers in history. He is considered one of China's greatest emperors.
