'The Great Promulgation Campaign' or 'Great Teaching Movement'. The first attempt by the Meiji government from 1870—1884 to formulate a nation-uniting religion. The campaign comprised three elements: (1) The three great teachings (taikyo, sanjo no kyosoku), (2) the Daikyo-in or Great Teaching Institute in Tokyo where the movement was based and (3) an army of national evangelists (kyodo-shoku) drawn from many different walks of life (actors, preachers, storytellers, clergy of the new religions etc.) trained in the national creed.
