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.
Dayan Khan Dayan Khan (Mongolian: Даян Хаан ) (given name: "Batumöngke"; 1464–1517/1543) was a Mongol khan who reunited the Mongols under Chinggisid supremacy in the Northern Yuan dynasty based in Mongolia. His reigning title, "Dayan", means the "Great Yuan", as he enthroned himself as Great Khan of the Great Yuan, though the Yuan dynasty, the principal khanate of the Mongol Empire, had already been overthrown by the Chinese Ming dynasty a century earlier (1368).
