Cause of formation
The Korean Presbyterian Church split for the third time (1951, 1953, and 1959) when the church divided for and against Park Hyung- Ryong (박형룡 朴亨龍, 1897 ~ 1978), president of the Presbyterian Seminary Society of the General Assembly. The anti-Park party is called 대한예수교장로회(통합)'Tonghap' (the united body) and the pro-Park party is called 대한예수교장로회(합동)'Hapdong' (the union body). The divisions from all three splits during the 50s still exist. The divisions from the third split between Tonghap and Hapdong respectively are still the largest Presbyterian dominations in South Korea.
