of black Baptist churches in the South, in 1895 church officials organized a new Baptist association, the National Baptist Convention. This was the unification of three national black conventions, organized in 1880 and the 1890s. It brought together the areas of mission, education and overall cooperation. Despite founding of new black conventions in the early and later 20th century, this is still the largest black religious organization in the United States. These churches blended elements from underground churches with elements from freely established black churches. The postwar years were marked by a separatist impulse as blacks exercised the right to move and gather beyond white supervision or control. They developed black churches, benevolent societies, fraternal orders and fire companies. In some areas they moved from farms into towns, as in middle Tennessee, or to cities that needed rebuilding, such as Atlanta. Black churches were the focal points of black communities, and their members' quickly seceding from white churches demonstrated their desire to manage their own affairs independently of white supervision. It also showed the prior strength of the "invisible church" hidden from white eyes. Black preachers provided leadership, encouraged education and economic growth, and were often the primary link between the black and white communities. The black church established and/or maintained the first black schools and encouraged community members to fund these schools and other public services. For most black leaders, the churches always were connected to political goals of advancing the race. There grew to be a tension between black leaders from the North and people in the South who wanted to run their churches and worship in their own way. Since the male hierarchy denied them opportunities for ordination, middle-class women in the black church asserted themselves in other ways: they organized missionary societies to address social issues. These societies provided job training and reading education, worked for better living conditions, raised money for African missions, wrote religious periodicals, and promoted Victorian ideals of womanhood, respectability, and racial uplift.

Their history as a centers of strength for the black community made them natural leaders in this moral struggle. In addition they had often served as links between the black and white worlds.
