In this Saturday, June 25, 2005 file photo, Unification Church leader Rev. Sun Myung Moon speaks during his "Now is God's Time" rally in New York. Moon, self-proclaimed messiah who turned his Unification Church into a worldwide religious movement and befriended North Korean leaders as well as U.S. presidents, died on Monday, September 3, 2012, at a church-owned hospital near his home in Gapyeong, northeast of Seoul. He was 92.

Moon, born in a town that is now in North Korea, founded his religious movement in Seoul in 1954 after surviving the Korean War. He preached new interpretations of lessons from the Bible.

The church gained fame, and notoriety, in the 1970s and '80s for holding mass weddings of thousands of followers, often from different countries, whom Moon matched up in a bid to build a multicultural religious world.

"International and intercultural marriages are the quickest way to bring about an ideal world of peace," Moon said in a 2009 autobiography. "People should marry across national and cultural boundaries with people from countries they consider to be their enemies so that the world of peace can come that much more quickly."

The church was accused of using devious recruitment tactics and duping followers out of money; parents of followers in the United States and elsewhere expressed worries that their children were brainwashed into joining. The church responded by saying that many other new religious movements faced similar accusations in their early stages.

The Unification Church claims millions of members worldwide, though church defectors and other critics say the figure is no more than 100,000.

In later years, the church adopted a lower profile and focused on building a business empire that included the Washington Times newspaper, the New Yorker Hotel in Manhattan, Bridgeport University in Connecticut, as well as a hotel and a fledgling automaker in North Korea. It acquired a ski resort, a professional soccer team and other businesses in South Korea, and a seafood distribution firm that supplies sushi to Japanese restaurants across the U.S.

In the 1980s Moon was sentenced to 18 months at a U.S. federal prison for tax evasion. The church said the U.S. government persecuted Moon because of his growing influence and popularity with young people in the United States.

While preaching the gospel in North Korea in the years after the country was divided into the communist-backed North and U.S.-allied South, Moon was imprisoned there in the late 1940s for allegedly spying for South Korea - a charge Moon disputed.

Moon began rebuilding his relationship with North Korea in 1991, when he met the country's founder Kim Il Sung in the eastern industrial city of Hamhung.

When Kim Il Sung died in 1994, Moon sent a condolence delegation to North Korea, drawing criticism from conservatives at home.

Moon also developed good relationships with conservative American leaders, including former Presidents Richard Nixon, Ronald Reagan and George H.W. Bush.
