in American history, a religious social-reform movement that was prominent from about 1870 to 1920, especially among liberal Protestant groups dedicated to the betterment of industrialized society through application of the biblical principles of charity and justice. Especially persuasive of the movement's views were the works of Charles Monroe Sheldon (Sheldon, Charles Monroe) (e.g., In His Steps; “What Would Jesus Do?”; 1897) and Walter Rauschenbusch (Rauschenbusch, Walter) (e.g., Christianity and the Social Crisis; 1907). labour reforms—including abolition of child labour, a shorter workweek, a living wage, and factory regulation—constituted the Social Gospel's most prominent concerns. During the 1930s many of these ideals were realized through the rise of organized labour and the legislation of the New Deal.
