Kim Il-sung: A Detailed Biography

Kim Il-sung (1912–1994) was the founder and supreme leader of the Democratic People’s Republic of Korea (North Korea) from 1948 until his death. Guerrilla fighter, Soviet-installed ruler, architect of the Korean War, and creator of the Juche ideology, he established one of the world’s most totalitarian regimes and began the Kim dynasty that continues today. This biography covers his Manchurian guerrilla years, Soviet backing, founding of North Korea, Korean War, cult of personality, and death, as documented by the Encyclopaedia Britannica, the Wilson Center, and the BBC.

Early Life and Guerrilla Years

Birth in Mangyongdae

Born Kim Song-ju on April 15, 1912, in Mangyongdae near Pyongyang (official date; likely 1911), his family fled Japanese occupation to Manchuria in 1920. He joined anti-Japanese guerrilla groups in the 1930s, taking the nom de guerre “Kim Il-sung” after a legendary fighter, as detailed by the NK News.

Soviet Training and Return

By 1940 Japanese pressure forced Kim into the USSR. Trained by the Red Army, he became a captain and spent WWII in a camp near Khabarovsk. In 1945 Soviet troops installed him as head of the provisional North Korean administration.

Founding of North Korea (1948)

On September 9, 1948, the Democratic People’s Republic of Korea was proclaimed with Kim Il-sung as Premier. Land reform, nationalisation, and purges eliminated opposition.

Korean War (1950–1953)

With Stalin’s approval, Kim launched the invasion of South Korea on June 25, 1950. The war killed millions and ended in stalemate. Kim consolidated absolute power, as documented by the History.com.

Juche and Cult of Personality

In the 1950s Kim developed Juche (“self-reliance”) as North Korea’s ideology. A massive personality cult portrayed him as infallible — eternal president after death, as analysed by the National Geographic.

Personal Life

Married Kim Jong-suk (died 1949; mother of Kim Jong-il) and later Kim Song-ae. Had at least six children. Known for heavy smoking and love of movies.
