Republic of Cadasa (1942–1945)

"For the current Republic of Cadasa, see Cadasa"The Republic of Cadasa (Japanese: , Kadasa-kyōwakoku) was a client state of the during, from 1942 to 1945.

Background
In 1939, World War II broke out. As many Cadasans still held discontent over Cadasa's participation in the First World War, not many people supported Cadasan entry into WWII. President T. H. Koh echoed these sentiments, declaring that, as long as he was president, "Cadasa will never lose another man due to war".

However, Koh made a mistake when he appointed James Teoh, a known Japanophile, to the post of vice-president in 1941. On July 3, 1942, Koh died due to poisoning, and Teoh automatically became president.

The republic
On the same day, Teoh announced a "pact of friendship" between the Empire of Japan and Cadasa, whose relations were previously neutral. During Koh's tenure, relations decreased due to Koh disagreeing with the "savagery of the Imperial Army", referencing the Nanking Massacre and Second Sino-Japanese War.

On July 6, 1942, Teoh ended Cadasan neutrality and declared war on the United States, United Kingdom, Soviet Union, and China, officially entering the war.
