United States of Tseng

See also: Japanese invasions of Tseng The United States of Tseng (Chinese: 曾島合眾國; pinyin: Zēngdǎo Hézhòngguó) was a puppet state of several European powers that existed from 1936 to 1938. It is considered to be the predecessor to the Tseng Republic as it was the first sovereign nation that ruled all over Tseng Island. 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.

Internationally recognized by most European powers, 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.

As the British part of the island was the most influential and powerful out of all three Tsengian colonies, they had the most impact on deciding the framework of the state. They based the United States of Tseng off a constitutional monarchy, with the British monarch being the head of state, and the prime minister Samuel Adonis being the head of government. This resulted in much anger by the French, but due to the severity of the situation, they decided to keep quiet until the Japanese threat was gone.
