조선공산당
On June 30, 1949, the Workers Party of North Korea and the Workers' Party of South Korea merged, forming the Workers' Party of Korea, at a congress in Pyongyang. Both parties traced their origins to the Communist Party of Korea. Kim Il-sung of the Workers Party of North Korea became the party Chairman and Pak Hon-yong, who had been leader of the Workers Party of South Korea as well as the earlier Communist Party of Korea, and Ho Ka-i becoming deputy chairmen. There were a total of ten members of the first DPRK Politiburo. The other members were Yi Sung-yop, Kim Sam-yong, Kim Chaek, Kim Tu-bong, Pal Il-u, and Pak Chong-ae. Most were later purged by Kim Il-sung.
