The newly allied armies captured Beijing on June 6. The Shunzhi Emperor was invested as the "Son of Heaven" on October 30. The Manchus, who had positioned themselves as political heir to the Ming emperor by defeating the rebel Li Zicheng, completed the symbolic transition by holding a formal funeral for the Chongzhen Emperor. However the process of conquering the rest of China took another seventeen years of battling Ming loyalists, pretenders and rebels. The last Ming pretender, Prince Gui, sought refuge with the King of Burma, but was turned over to a Qing expeditionary army commanded by Wu Sangui, who had him brought back to Yunnan province and executed in early 1662.
