The Church of England Protection Society was formed in 1859, and was renamed the English Church Union in 1860, when it incorporated several local Church societies. Its object was to defend and propagate High Church principles. In 1934 the English Church Union was united with the Anglo-Catholic Congress to form the Church Union. The organisation continues to be administered from Faith House, Westminster, and to publish books, tracts and magazines. The Anglo-Catholic Congress was first held in London in 1920 and continued to meet in different locations around England until the 1950s. It incorporated a number of smaller organisations, including the Fiery Cross Association (1920s-1930s), Catholic Literature Association (1890s-1920s) and Pilgrimage Association (1920s-1930s).
