Korean reunification in the context of "North Korea"

South Korea, officially the Republic of Korea (ROK), is a country in East Asia. It constitutes the southern half of the Korean Peninsula and borders North Korea along the Korean Demilitarized Zone, with the Yellow Sea to the west and the Sea of Japan to the east. Like North Korea, South Korea claims to be the sole legitimate government of the entire peninsula and adjacent islands. It has a population of about 52 million, of which half live in the Seoul metropolitan area, the ninth most populous metropolitan area in the world; other major cities include Busan, Daegu, and Incheon.

The Korean Peninsula was inhabited as early as the Lower Paleolithic period. Its first kingdom was noted in Chinese records in the early seventh century BC. From the mid first century BC, various polities consolidated into the rival kingdoms of Goguryeo, Baekje, and Silla. The lattermost eventually unified most of the peninsula for the first time in the late seventh century AD, while Balhae succeeded Goguryeo in the north. The Goryeo dynasty (918–1392) achieved lasting unification and established the basis for the modern Korean identity. The subsequent Joseon dynasty (1392–1897) generated cultural, economic, and scientific achievements and also established isolationism starting from the mid-17th century. The succeeding Korean Empire (1897–1910) sought modernization and reform but was annexed in 1910 into the Empire of Japan. Japanese rule ended following Japan's surrender in World War II, after which Korea was divided into two zones: the Soviet-occupied northern zone and the United States-occupied southern zone. After negotiations on reunification failed, the southern zone became the Republic of Korea in August 1948, while the northern zone became the communist Democratic People's Republic of Korea the following month.

The Panmunjom Declaration for Peace, Prosperity and Reunification of the Korean Peninsula was adopted between the Supreme Leader of North Korea, Kim Jong-un, and the President of South Korea, Moon Jae-in, on 27 April 2018, during the 2018 inter-Korean Summit on the South Korean side of the Peace House in the Joint Security Area.

According to the declaration, the governments of South Korea (ROK) and North Korea (DPRK) agreed to cooperate on officially ending the Korean War and the Korean conflict, beginning a new era of peace and sharing commitments in ending divisions and confrontation by approaching a new era of national reconciliation, peace, reunification and prosperity and improvements to inter-Korean communication and relations.

The military history of the United States in Korea began after the defeat of Japan by the Allied Powers in World War II. This brought an end to 35 years of Japanese occupation of the Korean peninsula and led to the peninsula being divided into two zones; a northern zone occupied by the Soviet Union and a southern zone occupied by the United States. After negotiations on reunification, the latter became the Republic of Korea or South Korea in August 1948 while the former became the Democratic People's Republic of Korea or North Korea in September 1948. In June 1949, after the establishment of the Republic of Korea, the U.S. military completely withdrew from the Korean Peninsula.

In 1950, a North Korean invasion began the Korean War, which saw extensive U.S.-led U.N. intervention in support of the South, while the North received support from China and from the Soviet Union.

Sun Myung Moon (Korean: 문선명; Hanja: 文鮮明; born Moon Yong-myeong; 6 January 1920 – 3 September 2012) was a Korean religious leader, also known for his business ventures and support for conservative political causes. A messiah claimant, he was the founder of the Unification Church, whose members consider him and his wife, Hak Ja Han, to be their "True Parents", and of its widely noted "Blessing" or mass wedding ceremonies. The author of the Unification Church's religious scripture, the Divine Principle, was an anti-communist and an advocate for Korean reunification, for which he was recognized by the governments of both North and South Korea. Businesses he promoted included News World Communications, an international news media corporation known for its American subsidiary The Washington Times, and Tongil Group, a South Korean business group (chaebol), as well as other related organizations.

Moon was born in what is now North Korea. When he was a child, his family converted to Christianity. In the 1940s and 1950s, he was imprisoned multiple times by the North and South Korean governments during his early new religious ministries, formally founding the Holy Spirit Association for the Unification of World Christianity, simply known as the Unification Church, in Seoul, South Korea, in 1954.
