of Pope Pius X. The Union was headed in 1909–16 by Count Ottorino Gentiloni. The Gentiloni pact of 1913 brought many new Catholic voters into politics, where they supported the Liberal party of Prime Minister Giovanni Giolitti. By the terms of the pact, the Union directed Catholic voters to Giolitti supporters who agreed to favor the Church's position on such key issues as funding private Catholic schools, and blocking a law allowing divorce. However the Socialists divided over Italy's conquest of Libya in 1911–12. Meanwhile, the nationalists grew in power. The Gentiloni pact brought new Catholic support to the Liberals, who were thus moving to more conservative positions. Increasingly the Radicals and Socialists on the Left rejected Giolitti, especially his pro-Catholic policies. In October 1913 he formed a new government with the clericals. Giolitti stepped down and the new government was headed by Antonio Salandra, a right-wing conservative.

Italian control of the area was weak, leading to twenty years of conflict with the Senussi religious order which was the main political and religious authority in the Libyan hinterlands. The invasion of Libya did mark a turn in direction for the opposition to the Italian government, revolutionaries became divided, some adopting nationalist lines, while others retaining socialist lines. The annexation of Libya caused nationalists to advocate Italy's domination of the Mediterranean Sea by occupying Greece as well as the Adriatic coastal region of Dalmatia. While the success of the Libyan War improved the status of the nationalists, it did not help Giolitti's administration as a whole. The war radicalized the Italian Socialist Party with
