Bonomi, Ivanoe (1873–1952)

Italian socialist politician, prime minister 1921–22 and 1944–45. An opponent of Mussolini's seizure of power, he left politics in 1924, but after 1942 was a leading figure in the anti-fascist struggle. He replaced Pietro Badoglio as prime minister in 1944 and established a broad, antifascist coalition government. In 1945 he was forced to resign in favour of the more radical Ferruccio Parri. He became president of the senate in 1948.

Bonomi was first elected to parliament in 1909, following an earlier career in journalism. After his expulsion from the Italian Socialist Party in 1912, he founded a reformist socialist movement, and between 1916 and 1921 accepted various ministerial appointments under Vittorio Orlando, Francesco Nitti, and Giovanni Giolitti.

Originally a graduate in natural sciences and law, Bonomi took up journalism in 1898, writing for Avanti! and Critica socialista.
