Manchukuo

Manchukuo (simplified Chinese: 满洲国; traditional Chinese: 滿洲國; pinyin: Mǎnzhōuguó; literally "Manchu state") or Manshū-koku (Japanese: 満州国) was a puppet state in modern northeast China and Inner Mongolia, governed under a form of constitutional monarchy. The area, collectively known as Manchuria, was designated by China's erstwhile Qing Dynasty as the "homeland" of the ruling family's ethnic group, the Manchus. In 1931, Japan seized the region following the Mukden Incident and installed a pro-Japanese government 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.
