Consequences of the murder
Eminent historians of the time, including Pollard and Mack Smith, thought that Mussolini probably had knowledge of the plot but did not order it.
However, recent studies by
Mauro Canali have come to a different conclusion. Canali contends that Mussolini gave the order to kill Matteotti because the Socialist deputy had obtained documents proving that Mussolini and other Fascist leaders had accepted bribes from the American
Sinclair Oil company in exchange for exclusive rights to explore and exploit any Italian oil reserves they found.
Matteotti was bundled into a car and stabbed repeatedly as he struggled to escape. His body was found 20 miles from Rome after an extensive search precipitated by Matteotti's wife's plea to Mussolini himself. Whoever the killer was, he was seen as a hero by many of the zealous fascists in Italy.
The death of Matteotti sparked widespread Fascist criticism: a
general strike was threatened in retaliation and for a while it seemed that domestic and international pressure would force Victor Emmanuel into action, but as the King was supported so strongly by Mussolini and was worried he would otherwise be replaced by his cousin, he did nothing. The King feared that there would be a civil war or a socialist uprising if he forced Mussolini out of power. If the socialists were to obtain power in Italy the monarchy would be abolished and of course the king did not want this. Moreover, the King was under pressure from his mother who was a Fascist supporter. Thus, Mussolini was soon able to use his influence over the media combined with a speech taking a complicated stance over who was responsible for the murder to regain the people's confidence. Using political skill Mussolini managed to take credit from his supporters while avoiding much of the blame. Most
anti-Fascist parties left the
Italian Parliament in protest - an event which came to be known as the
Aventine Secession; albeit in a less obvious manner than the previous
Acerbo Law, this event arguably served to consolidate the grip of the PNF on Italian society.
Matteotti's son, Matteo Matteotti, became a Social Democratic parliamentary deputy after World War II, served as Italy's minister of tourism in 1970-72 and minister of foreign trade in 1972-74, and died in 2000.
