Party Foundation Day in North Korea Date in the current year: October 10, 2024

The Communist Party of Korea (CPK) is a forerunner of the Workers' Party of Korea (WPK). The CPK was founded in 1925 but due to rival fractions the party was disbanded in 1928. The Communists decided to revive the party once again only in 1945, after North Korea gained independence.

On October 10, 1945 the North Korean Bureau of the Communist Party of Korea was established, that technically marked the birth of the Workers' Party of Korea. The first chairman of the party, Kim Yong-bom, was replaced by Kim Il-sung, who became General Secretary in 1946 and later the first President of North Korea.

In 1946 the CPK established the Workers' Party of North Korea. It merged with the Workers' Party of South Korea in 1949 to form the Workers' Party of Korea. Although this event took place on June 30, 1949, Party Foundation Day celebration refers to establishment of the North Korean Bureau of the Communist Party of Korea, that via different changes has become a ruling power in North Korea.
