Pius XI's Promotion of the Italian Model of Catholic Action in the World-Wide Church.

During his pontificate, Pius xi (1922–39) vigorously promoted the ‘export’ of the Italian model of Catholic Action to the rest of the Church as the organisational blueprint for Catholic lay activism, particularly in the battle against atheistic Communism. He was assisted by Mgr, later Cardinal, Giuseppe Pizzardo, the head of Italian Catholic Action. The successes and failures of this campaign are tracked through documents available since the opening of the files of the apostolic nunciatures and delegations and the Extraordinary Ecclesiastical Affairs section of the Secretariat of State for Pius xi's pontificate in the Vatican Archives.
