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.
Southern Ming The Southern Ming was a loyalist movement that was active in southern China following the Ming dynasty's collapse in 1644. The Ming were overthrown when peasant rebels captured Beijing. Ming generals then opened the gates of the Great Wall to the nomadic Manchu tribes, hoping they would fight the rebels. Loyalists fled to Nanjing, where they enthroned the Zhu Yousong, Prince of Fu. The Nanjing regime lasted until 1645, when the Qing captured Nanjing. Later, a series of pretenders held court in various southern Chinese cities.
