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.
Sixteen Kingdoms The Sixteen Kingdoms, less commonly the Sixteen States, was a chaotic period in Chinese history from 304 to 439 when the political order of northern China fractured into a series of short-lived sovereign states, most of which were founded by the "Five Barbarians" who had settled in northern China during the preceding centuries and participated in the overthrow of the Western Jin dynasty in the early 4th century. The period ended with the unification of northern China by the Northern Wei in the early 5th century.
