Candidate passages:
Kim was born to Kim Il-sung and Kim Song-ae, Kim Il-sung's former secretary.
Kim had one younger brother, Yong-il, and one older half-sister, Kyong-hui, who would go on to marry senior official Chang Sung-taek.
He was named after another son with the same name, who was born in Vyatskoye in 1944; that son, also known as Shura Kim, allegedly drowned in Pyongyang in 1947.
He graduated from Kim Il-sung University with a major in economics, and later attended the Kim Il-sung National War College, following which he was appointed a battalion commander.
Kim Pyong-il's rivalry with half-brother Kim Jong-il goes back to the 1970s.
In those days, Kim Pyong-il was known as a womaniser who threw raucous parties; sometimes, attendees at these parties would shout, "Long live Kim Pyong-il!".
Kim Jong-il knew that this could be portrayed as a threat to the cult of personality surrounding their father Kim Il-sung, and reported the matter; Kim Il-sung was reportedly infuriated, and thus Kim Pyong-il fell out of favour with his father while Kim Jong-il strengthened his position. 
The country's supreme leaders have had hymns dedicated to them that served as their signature tune and were repetitively broadcast by the state media: "Song of General Kim Il-sung" (for Kim Il-sung)  "Song of General Kim Jong-il" and "No Motherland Without You" (for Kim Jong-il)  "Footsteps", "Onwards Toward the Final Victory" and "We Will Follow You Only" (for Kim Jong-un)  
The 1st plenum of the 6th Central Committee, to elect the central party leadership, was held immediately after the 6th Congress.
34 members were elected to the 6th Politburo, an increase from 15 in the 5th Politburo.
Of these 34, 19 were full members and 15 candidate members.
Five members were elected to the Presidium, and Kim Jong-il was ranked fourth in the hierarchy of the Politburo and the Presidium.
The 6th Secretariat was composed of nine members, with Kim Jong-il ranked second.
The size of the Secretariat did not change from the 5th Congress, but of its nine members only Kim Il-sung was from the party's "revolutionary generation" (60% of the members of the 5th Secretariat came from that generation).
Kim Il-sung and Kim Jung-rin were the only incumbents to be reelected.
The elected 6th Central Military Commission (CMC) was composed of 19 members, of which Kim Jong-il ranked third (behind Kim Il-sung and Oh Jin-u).
This marked the first time in the party's history that the CMC membership was made public.
Kim Il-sung and Kim Jong-il became the only officials with seats in all four bodies: the Presidium, Politburo, Secretariat and CMC.
While Kim Jong-il was outranked in the Presidium, Politburo and Secretariat, none of the members who outranked him had positions in other bodies (except for Oh Jin-ju, second-ranked member of the CMC).
Below is a list of members (and their respective rankings) of the Presidium, full and candidate members of the Politburo, Secretariat and CMC:The 1st plenum saw the "revolutionary generation" retire from their executive posts, surrendering them to the new generation of Kim Jong-il; however, they still controlled the highest organs of power: the Presidium and the Politburo.
The plenum saw the disappearance of Kim Yong-ju (Kim Il-sung's brother, considered his chosen successor before Kim Jong-il), Kim Dong-gyu, Ryu Jang-sik and Lee Yong-mu from important party positions.
The reason for the purge is unknown, but presumably linked to Kim Il-sung's time-consuming consolidation of his son's power base. 
In September 1951, Kim Il-sung and Ho Ka-i had a dispute over how to reorganize the tattered party and how to handle party members who were not completely loyal.
The party was split on how they should set up its government and what sort of actions they should take in doing so.
Kim Il-sung said that the Korean war had helped to distinguish between the loyal and disloyal members of the party and those who went against the party should be punished via legal channels, avoiding any indiscriminate purges.
Ho Ka-i, who was the chair of the inspection committee, did the exact opposite, conducting indiscriminate purges of low-ranking party members to check their loyalty to the Party.
Numbers from North Korea suggest that Ho Ka-i expelled and punished over 450,000 of the party’s 600,000 members during the war.
Kim Il-sung felt that Ho Ka-i was using harsh measures, punishing any member who failed to show the newly issued membership card, but Ho Ka-i failed to cooperate.
The main issue between the two men was whether to build an elite Communist party that takes after the Soviet Union or a mass party which the Soviet occupation authorities had suggested.
Ho Ka-i opted to follow the Soviet Union model while Kim Il-sung wanted the mass party which the Soviet occupation authorities suggested.
Ho Ka-i, according to Kim Il-sung at a later date, had desired an elite Communist party while Kim wanted a strong mass party that built up all of the country’s unique features.
Later, Kim Il-sung reinstated all the expelled members and Ho Ka-i, instead was purged.
Kim Il-sung took advantage of Ho Ka-i’s misfortune, ridiculing Ho Ka-i about party matters as well as accusing him of being secretive and acting on personal heroism.
In November 1951, Ho Ka-i was removed from his posts.
This act greatly weakened the influence of Soviet Koreans, men who were sent from the USSR to help implement their power into the new Korean country, which was part of the goal of Kim Il-sung, in order to transition into power.
But Kim Il-sung didn’t completely remove Ho Ka-i from political influence, appointing Ho Ka-i as deputy prime minister.
Kim Il-sung and his followers wanted Ho Ka-i out of that position, accusing him of many dishonorable actions such as Ho Ka-i’s secret desire to become dictator, his individual heroism and ignoring the needs of Korea but concerned only with his own gain.
At the sixth joint plenum of the Central Committee on 4 August 1953, it was reported that Ho Ka-i had committed suicide though some suggest that he was murdered by one of Kim Il-sung’s hired men.
Official reports show that he was reported dead on 2 July 1953 at 9:30pm.
In any case Kim Il-sung took this as an opportunity to condemn Ho Ka-i for his cowardly act of killing himself.
Ho Ka-i is not recognized in North Korea’s history as being an influential figure.
Rather, he is remembered as a coward who killed himself after unsuccessfully attempting to become dictator of the new country. 
The original train station, reconstructed in 1975, is now a "revolutionary museum" as it was here that Kim Il-Sung boarded a train to Pyongyang after his return to Korea.
In much the same way, the city's old customs building and a Japanese villa - both destroyed in the Korean War - were rebuilt as museums due to having Kim Il-Sung pass through them in the 1940s.
