The geographically disparate Northern and Southern wings of the Christian movement did eventually discover each other, and they formed a convention in 1820. At that time, they agreed on a general list of five (some scholars have claimed six) principles unifying the otherwise diverse congregations. The unity did not survive engrossing controversies over slavery and the ensuing Civil War. The "Christian Connection," as was also the case with American Protestant groups such as the Methodists, Presbyterians, and Baptists, split once again into Northern and Southern factions. The Northern group catalyzed the split, as many of its leaders, much like those of the Congregationalists, strongly denounced slavery. The Northerners used the schism as an occasion to legally take denominational form, in 1850. Despite the bitterness of the split, Christians in both sections reunited much sooner than did the other separated groups, forming the General Convention of the Christian Church in 1890.
