Initially, Hong Taiji, the second major head of the 17th century Qing Manchu state, was quite reluctant to expand south into Ming territory, until he approved a risky invasion of Hebei in late 1643. He'd die before seeing the endeavor completed under his son and successor, who'd go on to conquer Beijing and eventually the vast majority of China's modern territory.
But what if the Qing emperor had instead decided not to expand into Ming territory in the 1640's, and the Manchu regime had remained confined to the north? What would be the consequences of a mini-Qing empire on Asian history from there on in? For how long would they be able to keep the Koreans and Mongols as vassals, for example?
