The area was the homeland of the Manchus, including the emperors of the Qing dynasty. In 1931, the region was seized by Japan following the Mukden Incident. A pro-Japanese government was installed one year later with Puyi, the last Qing emperor, as the nominal regent and later emperor. Manchukuo's government was dissolved in 1945 after the surrender of Imperial Japan at the end of World War II. The territories claimed by Manchukuo were first seized in the Soviet invasion of Manchuria in August 1945, and then formally transferred to Chinese administration in the following year.
