United States of Tseng

"See also: Japanese invasions of Tseng"The United States of Tseng was a state that existed from 1936 to 1938. It is considered to be the predecessor to the Tseng Republic. The reason for the UST's existence was to defend the island from Japan, who invaded (and failed) in January 1936. The UST defended the island from the Japanese two more times before finally failing in 1938, later it was renamed to Tseng.

The United States of Tseng was known for less attacks and rebellions in the Tsengian independence movement because many people believed that the UST was the first step in establishing autonomy. However, Japanese occupation and AFJAT ended those plans until the declaration of independence of Tseng in 1946.
