Giacomo Matteotti, an Italian socialist politician, was kidnapped and then murdered by members of the Fascist party.
Matteotti had been a leading member of the Italian Socialist Party but, following divisions in the party, he co-founded the Unitary Socialist Party in 1922. Matteotti became an outspoken critic of Mussolini and the Fascists, and publicly criticised the new political organisation’s use of violence in a pamphlet published in 1921.
Three years later, in 1924, Matteotti published a book that was highly critical of the new government called The Fascisti Exposed: A Year of Fascist Domination.
On 30 May that year he made a particularly zealous speech in the Chamber of Deputies in which he criticised Mussolini and accused the Fascists of only winning the recent election due to their use of violence to intimidate the public.
Less than two weeks later, on June 10, Matteotti disappeared. His neighbours reported an unknown car’s registration plate to the police who quickly found the car with blood on the back seat. Although this didn’t directly link the car to Matteotti’s disappearance, Mussolini ordered the arrest of Amerigo Dumini and other members of his recently-created Ceka secret police.
Opposition deputies showed their opposition to the Fascists by moving from the Chamber in an event known as the Aventine secession. Matteotti’s body was later found following an extensive search, showing that he had been stabbed in the chest with a carpenter’s file.
Despite a significant loss of political support, and the suggestion that he was involved in ordering the murder, Mussolini successfully turned events to his advantage. A speech in January 1925 saw him begin the transition to dictatorship when he stated that he would bring stability to Italy, even if that meant using force.
