Manchukuo was a puppet state in Northeast China and Inner
Mongolia. It was governed under a form of constitutional monarchy. The area was
collectively known as Manchuria by Japanese and westerners. The Qing Dynasty of
China designated the area as the “homeland” of the ruling family’s ethnic group
or the Manchus. However, the Manchus never used the term “Manchuria” to refer
to the place. The Japanese invaded the region in 1931.
