Socialist Sunday Schools (SSS) were set up to replace or augment Christian Sunday Schools in the United Kingdom, and later the United States. They arose in response to the perceived inadequacy of orthodox Sunday schools as a training ground for the children of socialists and the need for an organised, systematic presentation of the socialist point of view to teach the ideals and principles of socialism to children and young people.
