Kim Tu-bong in the context of Chu Sigyŏng

The general secretary of the Workers' Party of Korea (Korean: 조선로동당 총비서) is the leader of the Workers' Party of Korea (WPK), the ruling party in North Korea, and the country's supreme leader. Party rules stipulate that the party congress elects the general secretary. The party conference and the Central Committee are empowered to remove and elect the party leader. The general secretary is ex officio chairman of the WPK Central Military Commission and leads the work of the secretariat. Additionally, the general secretary is by right of office a member of the WPK Presidium, the WPK Politburo and the WPK Secretariat.

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 3 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 (WPSK) was established through the merger of the Communist Party of South Korea (led by Pak Hon-yong), 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 and the WPSK on 24 June 1949, the 2nd Central Committee elected Kim Il Sung as Chairman of the WPK Central Committee.

The Workers' Party of North Korea (Korean: 북조선로동당; Hancha: 北朝鮮勞動黨) was a communist party in North Korea from 1946 to 1949 and was a predecessor of the current Workers' Party of Korea. It was founded at a congress on 28–30 August 1946, by the merger of the northern branch of the Communist Party of Korea and the New People's Party of Korea. Kim Tu-bong, the leader of the New People's Party, was elected chairman of the party, while Chu Yong-ha and Kim Il Sung were elected as vice chairmen. At the time of establishment, the party is believed to have had about 366,000 members organized in around 12,000 party cells.

The New People's Party of Korea (Korean: 조선신민당; Hanja: 朝鮮新民黨) was a communist party in Korea. It was formed on 16 February 1946 by Korean Communists who had been exiled in China, later known as the Yan'an faction. The New People's Party had more moderate positions in some issues compared with the Communist Party of Korea, therefore it was rather popular with a wide range of Korean people. The leader of the party was Kim Tu-bong.

The 1st Central Committee of the Workers' Party of North Korea (WPNK) (Korean: 1차 북조선로동당중앙위원회) was elected by the 1st Congress on 30 August 1946 through the merger of the Communist Party of North Korea and the New People's Party of Korea, and remained in session until the election of the 2nd Central Committee on 30 March 1948. In between party congresses and specially convened conferences the Central Committee is the highest decision-making institution in the party and North Korea. The 1st Central Committee was not a permanent institution and delegated day-to-day work to elected central guidance bodies, such as the Political Committee, the Standing Committee and the Organisation Committee (membership not disclosed). It convened meetings, known as Plenary Sessions of the 1st Central Committee, to discuss major policies. A plenary session could be attended by non-members. These meetings are known as Enlarged Plenary Sessions. The party rules approved at the 1st Congress stipulated that the Central Committee needed to convene for a plenary session every third month. In total, the 1st Central Committee convened for twelve plenary sessions, of which eight were convened in 1947.

Forty-three members were elected to the 1st Central Committee, of which thirty-one were re-elected at the 2nd Congress. Its members convened for the 1st Plenary Session on 31 August 1946 and elected the 1st Organisation Committee, 1st Standing Committee and the 1st Political Committee, and voted in Kim Tu-bong as the WPNK Chairman and Kim Il Sung and Chu Yong-ha were elected vice chairmen. Despite their formal roles, real powers remained in Kim Il Sung's hands, and Kim Tu-bong played a more ceremonial role due to his unwillingness to partake in the day-to-day management of party affairs. In the 1st Plenary Session's aftermath, the party began establishing state structures known as provisional people's committees throughout the country, and in 1947 national elections to the People's Assembly was organised. At its first plenary session, the assembly elected a Presidium and designated Kim Tu-bong as its chairman and appointed the People's Committee (the government) and elected Kim Il Sung as its chairman. Of twenty-two government members, sixteen were members of the WPNK.

The 2nd Central Committee (2nd CC) of the Workers' Party of Korea (WPK) was elected at the 2nd Congress on 30 March 1948, and remained in session until the election of the 3rd Central Committee on 29 April 1956. In between party congresses and specially convened conferences the Central Committee is the highest decision-making institution in the WPK and North Korea. The 2nd Central Committee was not a permanent institution and delegated day-to-day work to elected bodies, such as the Political Committee, the Standing Committee, the Organisation Committee and the Inspection Committee in this case. It convened meetings, known as "Plenary Session of the [term] Central Committee", to discuss major policies. Only full members had the right to vote, but if a full member could not attend a plenary session, the person's spot was taken over by an alternate. Plenary session could also be attended by non-members, such meetings are known as "Enlarged Plenary Session", to participate in the committee's discussions. During its tenure it held five plenary sessions, one enlarged session, seven joint plenary sessions and four stand-alone plenums.

A feature of North Korean politics was its factionalism. Four loosely defined factions were struggling for dominance; Kim Il Sung's partisans, domestic communists, the Yanan group and the Soviet Koreans. The 2nd CC, which consisted of 67 members and 20 alternate members, was divided along factional lines. Of the 67 members, 30 had served in the 1st Central Committee. Among those not reelected were Chon Song-hwa and Chong Tal-hyon from the domestic faction. The position of the partisan faction was strengthened, with Kang Kon, Kim Kwang-hyop, Kim Kyong-sok and Pak Kum-chol being elected to the 2nd Central Committee. Despite this, the domestic faction had the most representation on the 2nd CC. Further the 2nd CC reelected Yanan communist Kim Tu-bong as Chairman of the Central Committee while partisan Kim Il Sung and Chu Yong-ha from the domestic group were elected to the office of Vice Chairman. All the members of the 1st Political Committee were re-elected, while two new were added; Kim Chaek and Pak Il-u. Upon the merger of the Workers' Party of North Korea and the Workers' Party of South Korea (WPSK) on 24 June 1949, the 2nd Central Committee merged with the 1st WPSK Central Committee and gained 31 new members. The newly expanded 2nd CC elected Kim Il Sung as chairman and domestic communist Pak Hon-yong and Soviet Korean Ho Ka-i as vice chairmen. Also, Ho Ka-i with domestic communists (and former WPSK members) Yi Sung-yop and Kim Sam-yong were elected First, Second and Third Secretary respectively in charge of administrative affairs. Thirty-six individuals were re-elected to the 3rd Central Committee, of these 29 were original members of the WPNK's 2nd CC.
