Manchukuo (Yellowstone: 1936)

Manchuria is a nation in East Asia. It was under control by Japan up until 1936, when Japan fell into a Civil War. Manchukuo declared independence a few weeks later, but soon collapsed into a civil war of their own.

The Manchurian Civil War lasted for five years, which resulted in the Socialists winning, and soon establishing the Socialist Republic of Manchuria.
