The Gentiloni Pact (Italian: Patto Gentiloni) was the 1913 agreement between Italian Prime Minister Giovanni Giolitti and Count Ottorino Gentiloni, president of the Catholic Electoral Union from 1909-1916, to swing Catholic voters behind Giolitti's coalition on 1913 general election.
Due to the evolving relationship with the Catholics and the Italian liberal state, in the 1910s Giolitti saw a way to further his clout and sway over the masses after the extension of suffrage to all adult males.
In 1904, Pope Pius X informally gave permission to Catholics to vote for government candidates in areas where the Italian Socialist Party might win. Since the Socialists were the arch-enemy of the Church, the reductionist logic of the Church led it to promote any anti-Socialist measures. Voting for the Socialists was grounds for excommunication from the Church.
The Vatican had two major goals at this point: to stem the rise of Socialism and to monitor the grassroots Catholic organizations (co-ops, peasant leagues, credit unions, etc.). Since the masses tended to be deeply religious but rather uneducated, the Church felt they were in need of conveyance so that they did not support improper ideals like Socialism or Anarchism.
Meanwhile, Italian Prime Minister Giolitti understood that the time was ripe for cooperation between Catholics and the liberal system of government.
The Gentiloni Pact was born out of a secret deal in the run-up to the 1913 general election between Catholic voters and Giolitti's Liberal candidates who promised to support Catholic policies, especially funding of Catholic private schools, and opposition to a law permitting divorce. It was estimated that over 200 deputies were elected through the Pact, enough to provide a majority for Giolitti.
