The relationship between Italian Fascism and the Catholic Church was mixed, as originally the Fascists were highly anti-clerical and hostile to Catholicism, though from the mid to late 1920s anti-clericalism lost ground in the movement as Mussolini in power sought to seek accord with the Church as the Church held major influence in Italian society with most Italians being Catholic. In 1929, the Italian government signed the Lateran Treaty with the Holy See, a concordat between Italy and the Catholic Church that allowed for the creation of a small enclave known as Vatican City as a sovereign state representing the papacy. This ended years of perceived alienation between the Church and the Italian government after Italy annexed the Papal States in 1870. Italian Fascism justified its adoption of antisemitic laws in 1938 by claiming that Italy was fulfilling the Christian religious mandate of the Catholic Church that had been initiated by Pope Innocent III in the Fourth Lateran Council of 1215, whereby the Pope issued strict regulation of the life of Jews in Christian lands. Jews were prohibited from holding any public office that would give them power over Christians and Jews were required to wear distinctive clothing to distinguish them from Christians.
