Sturzo, Luigi (lōēˈjē stōrˈtsō) [key], 1871–1959, Italian priest and political leader. He taught philosophy and sociology at a seminary in his native Sicily. In 1919 he founded the Popular (Roman Catholic) party and became its political secretary. In the elections of Nov., 1919, the new party secured about one fifth of the seats in parliament and became an important force in Italian politics. After the rise of Fascism Sturzo was forced to live in exile, first in England and later in the United States; his party was officially banned. It was revived, however, after Benito Mussolini's downfall and renamed the Christian Democratic party. Sturzo returned to Italy after World War II and in 1952 was made a senator for life.
