The split created the Southern Baptist Convention, while the northern congregations formed their own umbrella organization now called the American Baptist Churches USA (ABC-USA). The Methodist Episcopal Church, South had recently separated over the issue of slavery, and southern Presbyterians would do so shortly thereafter.
