Ruan Zhenduo served in many cabinet-level positions in what puppet state in Northeast China and Inner Mongolia, which was governed under a form of constitutional monarchy?
Manchukuo Manchukuo (: "Mǎnzhōuguó"literally: " State of Manchuria" ) was a puppet state in Northeast China and Inner Mongolia, which was governed under a form of constitutional monarchy. The area, collectively known as Manchuria by westerners and Japanese, was designated by China's erstwhile Qing Dynasty as the "homeland" of the ruling family's ethnic group, the Manchus. In 1931, the region was seized by Japan following the Mukden Incident and a pro-Japanese government was installed one year later with Puyi, the last Qing emperor, as the nominal regent and emperor. Manchukuo's government was abolished in 1945 after the defeat of Imperial Japan at the end of World War II. The territories formally claimed by the puppet state were first seized in the Soviet invasion of Manchuria in August 1945, and then formally transferred to Chinese administration in the following year.
Qing conquest of the Ming The Qing conquest of the Ming, also known as the Ming–Qing transition and as the Manchu conquest of China, was a period of conflict between the Qing dynasty, established by Manchu clan Aisin Gioro in Manchuria (contemporary Northeastern China), and the Ming dynasty of China in the south (various other regional or temporary powers were also associated with events, such as the short-lived Shun dynasty). Leading up to the Qing conquest, in 1618, Aisin Gioro leader Nurhaci commissioned a document entitled the Seven Grievances, which enumerated grievances against the Ming and began to rebel against their domination. Many of the grievances dealt with conflicts against Yehe, which was a major Manchu clan, and Ming favoritism of Yehe. Nurhaci's demand that the Ming pay tribute to him to redress the seven grievances was effectively a declaration of war, as the Ming were not willing to pay money to a former tributary. Shortly afterwards, Nurhaci began to rebel against the Ming in Liaoning in southern Manchuria.
