김두봉
The office traces its lineage back to the reestablishment of the Communist Party of Korea (CPK) on 14 September 1945 when Pak Hon-yong was elected Chairman of the CPK Central Committee. Later on 13 October 1945 the CPK established an internal North Korean Branch Bureau (NKBB) and nominated Hyon Chun-hyok as branch secretary. Hyon Chun-hyok was assassinated on 28 September 1945 and Kim Yong-bom was elected as branch secretary in his place. On 10 April 1946 the NKBB became independent of the CPK and changed its name to Communist Party of North Korea (CPNK). Later that year, on 30 August, the CPNK merged with the New People's Party of Korea to establish the Workers' Party of North Korea (WPNK). Kim Tu-bong was elected WPNK Chairman by the 1st WPNK Central Committee. In the meantime the Workers' Party of South Korea was established through the merger of the Communist Party of South Korea, New People's Party of Korea and a faction of the People's Party of Korea on 24 November 1946. The WPSK Central Committee elected Ho Hon as its party chairman. On the merger of the WPNK with the Workers' Party of South Korea on 24 June, the 2nd Central Committee elected Kim Il-sung as Chairman of the WPK Central Committee.
