Clerical fascism (also clero-fascism or clerico-fascism) is an ideology that combines the political and economic doctrines of fascism with clericalism. The term has been used to describe organizations and movements that combine religious elements with fascism, receive support from religious organizations which espouse sympathy for fascism, or fascist regimes in which clergy play a leading role. The term clerical fascism (clero-fascism or clerico-fascism) emerged in the early 1920s in the Kingdom of Italy, referring to the faction of the Roman Catholic Partito Popolare Italiano (PPI) which supported Benito Mussolini and his régime. It was supposedly coined by Don Luigi Sturzo, a priest and Christian democrat leader who opposed Mussolini and went into exile in 1924, although the term had also been used before Mussolini's March on Rome in 1922 to refer to Catholics in Northern Italy who advocated a synthesis of Roman Catholicism and fascism. Sturzo made a distinction between the "filofascists", who left the Catholic PPI in 1921 and 1922, and the "clerical fascists" who stayed in the party after the March on Rome, advocating collaboration with the fascist government. Eventually, the latter group converged with Mussolini, abandoning the PPI in 1923 and creating the Centro Nazionale Italiano. The PPI was disbanded by the fascist régime in 1926. The term has since been used by scholars seeking to contrast authoritarian-conservative clerical fascism with more radical variants. Christian fascists focus on internal religious politics, such as passing laws and regulations that reflect their view of Christianity. Radicalized forms of Christian fascism or clerical fascism (clero-fascism or clerico-fascism) were emerging on the far-right of the political spectrum in some European countries during the interwar period in the first half of the 20th century.
