Party Foundation Day is observed in North Korea every October 10, celebrating the anniversary of the foundation of the Workers' Party of Korea (WPK). This holiday marks the establishment of the North Korean Bureau of the Communist Party of Korea in 1945, which is considered the birth of the WPK. The Workers' Party has its roots in the Communist Party of Korea, founded in 1925, but was disbanded in 1928 due to internal conflicts. It was revived in 1945 following North Korea's independence. The first chairman of the party was Kim Yong-bom, who was succeeded by Kim Il-sung, the first President of North Korea. Although the WPK officially merged with the Workers' Party of South Korea in 1949, the celebration focuses on the earlier establishment of the North Korean Bureau. Party Foundation Day is a public holiday in North Korea, reflecting the party's significance in the country's political landscape.
