Manchukuo (traditional Chinese: 滿洲國; simplified Chinese: 满洲国; pinyin: Mǎnzhōuguó; Japanese: 滿洲国; 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, but the Manchus themselves never used "Manchuria" (滿洲) as a place name to refer to the area. 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.

BUT the wikijew is wrong in using the past tense for Dai Manchu Teikoku. The Manchu Government in Exile lives on!:
The Manchukuo Temporary Government is an organisation established in 2004 in Hong Kong. On its website, it claims to be the government in exile of Manchukuo, a Japanese puppet state with limited recognition which controlled northeast China from 1932 to 1945; it seeks to revive the state and to separate it from the People's Republic of China, which controls its claimed territory.
