It's one of the most controversial religious movements of the last century.Founded in Seoul in the 1950s by the Reverend Sun Myung-moon, Unificationism has attracted hundreds of thousands of members worldwide.
But the movement has been accused of cult-like practices, with its leader's followers dubbed "Moonies".
As Sun Myung-moon approaches his 90th birthday, he has handed over key responsibilities to one of his sons.
Hyung Jin-moon is just 30 years old, and grew up in the United States, where he studied theology at Harvard University.
