The Ventotene Manifesto, a seminal document advocating for a federalized Europe, was edited and released through the socialist underground newspaper Avanti! by Eugenio Colorni in the spring of 1943. This act remains his most significant political contribution, marking a bridge between his philosophical inquiries and the active resistance against the fascist regime in Italy.
Academic Background and Early Career
Educated at the University of Milan, Colorni pursued a career in philosophy, eventually securing a position teaching the subject at the University of Trieste. His early scholarly output included a critical study of Benedetto Croce’s aesthetics in 1932, followed by editorial work on Leibniz’s Monadology in 1935 and a 1938 study regarding Leibniz and mysticism. During the mid-1930s, he operated within intellectual circles, maintaining associations with figures such as Lelio Basso.

His opposition to the Italian fascist government led to his active involvement with the Giustizia e Libertà movement. On 9 September 1938, Italian authorities arrested Colorni in Trieste, citing both his political resistance and his Jewish background. He was subsequently interned at the Ventotene prison and later transferred to the town of Melfi. Despite these restrictions, he remained committed to his political goals.
European Federalist Advocacy
Colorni acted as a primary instigator of the European Federalist Movement and played a key role in promoting the ideology of the Ventotene Manifesto. His influence extended to his familial circle, notably affecting his brother-in-law Albert O. Hirschman. Hirschman later acknowledged this intellectual debt by dedicating his book Exit, Voice, and Loyalty to Colorni’s memory. Colorni married Ursula Hirschmann in 1935, and the couple had three daughters: Silvia, Renata, and Eva.
Death and Legacy
After escaping to Rome in 1943, Colorni continued his clandestine political work. On 28 May 1944, he was killed during a Nazi ambush at the Piazza Bologna, occurring just one week before Allied forces reached the city. He was posthumously honored with the Medal of Military Valour. His remains are interred at the monumental cemetery of Milan. His writings were collected and published in Florence in 1975 under the title Scritt.
