Sun Myung Moon 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, he 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.

The Unification Church (Korean: 통일교) is a new religious movement, derived from Christianity, whose members are called Unificationists or sometimes informally Moonies. Sun Myung Moon (1920–2012) began gaining followers after the Second World War. On 1 May 1954 in Seoul, South Korea, Moon formally founded the Holy Spirit Association for the Unification of World Christianity (HSA-UWC), the Unification Church's full name until 1994, when it was officially changed to the Family Federation for World Peace and Unification. It has a presence in approximately 100 countries around the world. Its leaders are Moon and his wife Hak Ja Han, whom their followers honor with the title "True Parents".
