The creation of the Sunday-School concept was an answer to the need to educate poor children. Robert Raikes, Hannah More and others started schools in the late 1700's, when the "Enabling Act" of 1779 allowed dissenters to teach without subscription the Church of England. The Sunday-School Society was formed in 1785, by William Fox and others. The London Sunday-School Union was formed in 1803, at Surrey Chapel, the church of Rowland Hill. The London Sunday-School Union became a very active publisher.
