Juche, officially the Juche idea, is the state ideology of North Korea and the official ideology of the Workers' Party of Korea. North Korean sources attribute its conceptualization to Kim Il Sung, the country's founder and first leader. Juche was originally regarded as a variant of Marxism–Leninism until Kim Jong Il, Kim Il Sung's son and successor, declared it a distinct ideology in the 1970s. Kim Jong Il further developed Juche in the 1980s and 1990s by making ideological breaks from Marxism–Leninism and increasing the importance of his father's ideas.

North Korea, officially the Democratic People's Republic of Korea (DPRK), is a country in East Asia. It constitutes the northern half of the Korean Peninsula and borders China and Russia to the north at the Yalu (Amnok) and Tumen rivers, and South Korea to the south at the Korean Demilitarized Zone. The country's western border is formed by the Yellow Sea, while its eastern border is defined by the Sea of Japan. North Korea, like its southern counterpart, claims to be the legitimate government of the entire peninsula and adjacent islands. Pyongyang is the capital and largest city.
