Chongjin (청진시, Ch'ŏngjin-si; Korean pronunciation: [tɕʰɔŋdʑin-ɕi]) is the capital of North Korea's North Hamgyŏng Province and the country's third largest city. From 1960 to 1967 and again from 1977 to 1985, Ch'ŏngjin was administered separately from North Hamgyŏng as a Directly Governed City (Chikhalsi). Prior to 1960, from 1967 to 1977, and since 1985, the city has been part of the North Hamgyŏng Province.

Ch'ŏngjin is divided into 7 wards ("Kuyŏk").

Originally Chongjin was only a small fishing village, located in northeastern Korea. In 1908, the Japanese, in order to facilitate a sea route for the northeast Chinese and Korean resources, opened this small fishing village as a trade port. In 2003, the government of North Korea formed a northeast Korean trade port here. The People's Republic of China and Russia have set up their Consulates in Chongjin. It is unique for a North Korean city to have a foreign consulate. Chongjin is the administrative centre of the North Hamgyong Province.

Chongjin is located in the northeast of North Korea, in North Hamgyong Province, near the East Korea Bay in the Sea of Japan (East Sea of Korea). Chongjin divides into 7 districts: the Central Business District expands to the south, and the coast section is near the lively Sosongchon River mouth. The city is 50 miles from the Chinese border, and its proximity is allowing a growing market of Chinese goods sold on the streets. Outside of the capital Pyongyang it has one of the largest markets for goods in the country.

Kim Il-sung (15 April 1912 – 8 July 1994) was the leader of the Democratic People's Republic of Korea, commonly referred to as "North Korea", from its establishment in 1948 until his death in 1994. He held the posts of Prime Minister from 1948 to 1972 and President from 1972 to his death. He was also the leader of the Workers' Party of Korea from 1949 to 1994 (titled as chairman from 1949 to 1966 and as general secretary after 1966).

His tenure as leader of North Korea has often been described as autocratic, and he established an all-pervasive cult of personality. From the mid-1960s, he promoted his self-developed Juche variant of communist national organization, which later replaced Marxism-Leninism as the ideology of the state in 1972. In the Library of Congress Country Study on North Korea in 2009, he was described as "one of the most intriguing figures of the twentieth century". He outlived Joseph Stalin by four decades, Mao Zedong by two, and remained in power during the terms of office of six South Korean presidents, 7 Soviet leaders, ten U.S. presidents, and twenty-one Japanese prime ministers.
