The transition from Ming to Qing, also known as the Manchu conquest of China or Ming-Qing transition, was a decades-long period of conflict between the Qing dynasty, established by the Manchu Aisin Gioro clan in Manchuria, and the Ming dynasty in China proper and later in South China. Various other regional or temporary powers were also involved in this conflict, such as the short-lived Shun dynasty. In 1618, before the start of the Qing conquest, Nurhaci, the leader of the Aisin Gioro clan, commissioned a document titled the Seven Grievances, in which he listed seven complaints against the Ming, before launching a rebellion against them. Many of the grievances concerned conflicts with the Yehe, a major Manchu clan, and the Ming's favoritism toward the Yehe at the expense of other Manchu clans. Nurhaci's demand that the Ming pay tribute to address the Seven Grievances was effectively a declaration of war, as the Ming were unwilling to pay money to a former vassal. Shortly thereafter, Nurhaci began to rebel against the Ming in Liaoning, a region in southern Manchuria.
At the same time, the Ming dynasty was struggling to survive amid increasing fiscal troubles and peasant rebellions. On April 24, 1644, Beijing fell to a rebel army led by Li Zicheng, a former minor Ming official who became the leader of the peasant revolt. Zicheng then proclaimed the Shun dynasty. At the time of the city's fall, the last Ming emperor, the Chongzhen Emperor, hanged himself on a tree in the imperial garden outside the Forbidden City. As Li Zicheng advanced toward him with his army, the general Wu Sangui, tasked by the Ming with guarding one of the gates of the Great Wall, swore allegiance to the Manchus and allowed them to enter China. Li Zicheng was defeated at the battle of Shanhai Pass by the combined forces of Wu Sangui and the Manchu prince Dorgon. On June 6, the Manchus and Wu entered the capital and proclaimed the young Shunzhi Emperor as the new Emperor of China.
