Italy's last prime minister before the Fascist leader Benito Mussolini gained power (Oct. 31, 1922).

After studying law, Facta became a journalist. He was elected deputy in 1891. He served as undersecretary first of justice and then of the interior in Giovanni Giolitti's coalition cabinet (1903–05). In succeeding ministries he was three times minister of finance and during the first six months of 1919 was minister of justice.

Facta formed his own cabinet in February 1922 but was defeated by an anti-Fascist coalition in July for not taking sufficiently strong action against Mussolini's Fascists. No other politician was willing, however, to form a cabinet in a country so dangerously racked by industrial and socialist agitation and by Fascist terrorism. Facta, therefore, on August 1 introduced a reconstituted government. Heading a divided cabinet and lacking personal courage, he failed to give precise orders when the Fascists marched on Rome (Rome, March on) (October 28), even though the chief of staff and the military commandant of Rome were prepared to quell the impending insurrection. Pressured by Liberal leaders, Facta belatedly proclaimed a state of siege and ordered the army to protect the government (October 28). King Victor Emmanuel III, however, refused to sign the decree. Facta was forced to resign, clearing the way for the Fascist ascendancy.
