Mario Missiroli

Mario Missiroli was a liberal journalist and newspaper editor whose criticism of fascist power in the countryside helped bring him into direct conflict with Benito Mussolini. The confrontation culminated in a duel in Milan on May 13, 1922. Missiroli entered it as a political opponent with no experience of swordsmanship; he left it wounded, while the agrarian conditions at the center of the dispute remained unresolved.

Journalist and political position

Missiroli is presented as an influential figure in Italian journalism: a liberal from the right, a Freemason, and the editor of Il Secolo. Before that, he had edited Il resto del Carlino, a Bologna daily from which local Fascist squads forced him out. His career thus placed him within the liberal press, but also exposed him to the coercive pressure that fascist organizations exerted on those who opposed them.

In the spring of 1922, Gabriele D’Annunzio emerged from his self-imposed seclusion at Gardone to condemn fascist conduct in the countryside as a form of agrarian slavery. The narrative identifies Missiroli as the man who seemed to have supplied D’Annunzio with the phrase. This association made Missiroli a target for Mussolini, who publicly insulted him. Missiroli answered not by withdrawing the criticism but by sending seconds with a challenge and imposing severe conditions for the encounter.

The rural conflict behind the accusation

The charge Missiroli was associated with had a concrete setting in Emilia. After the socialist leagues had been destroyed, peasants were left to face landowners without the collective protections those organizations had provided. Agrarian organizations dealt directly with landowners, and rural agreements that had previously operated collectively were abolished or altered, leaving individual farmers more exposed to employers’ demands.

When peasants resisted, strikes could be broken by replacement workers arriving from other provinces under the escort of armed Fascist squads. In the narrative’s account, the landowners’ campaign also reversed decades of social reforms and intensified the vulnerability of rural laborers. The accusation of slavery therefore condensed a dispute about who could negotiate working conditions, how rural contracts were organized, and what happened when workers tried to protest.

Mussolini had attempted to distinguish between large conservative landowners, whom he called agrarians, and small revolutionary landowners, whom he described as rural. His claim that fascism was rural rather than agrarian did not settle the issue. The countryside’s conduct contradicted the distinction: fascist organizations were working with landowners while armed squads helped suppress the resistance of peasants. Missiroli’s association with D’Annunzio’s denunciation brought that contradiction into the personal quarrel between the journalist and Mussolini.

The duel at Corso Sempione

Missiroli had never held a sword before. After Mussolini called him a coward in public, however, he accepted the challenge, sent his seconds, and began training every day with the well-known swordsman Giuseppe Mangiarotti. On May 13, he arrived at the Corso Sempione velodrome with Francesco Perrotti, a managing editor at his newspaper who served as his second. The duel’s formal arrangements were laid out in advance; the encounter was not an improvised exchange but a regulated contest set in motion by a public insult and a formally delivered challenge.

Mussolini attacked with visible anger. At the first thrust, his sword tip broke and he had to take up a replacement. Missiroli parried and remained composed, while Mussolini continued to press the attack. At the third assault Missiroli received a wound described as slight. The duelists returned to the piste, but the contest continued until the seventh attack, when Mussolini’s sword wounded Missiroli’s right forearm. The duel then ended. Neither man declared himself satisfied, leaving the confrontation without the formal resolution either could claim as a victory.

The scene also brought a private emergency into the public contest. While Missiroli was being treated, Perrotti, shaken by what had happened, asked the attending physician, Ambrogio Binda, to visit his young daughter, who was ill at the seashore in Salsomaggiore. Binda left for Salsomaggiore the following day. The next week, Perrotti took his own life. This episode does not resolve the political dispute, but it shows how the duel’s immediate circle extended beyond the two combatants and into the distress of those drawn into their roles as seconds and attendants.

Significance in the narrative

Missiroli’s role is both journalistic and confrontational. His association with the phrase agrarian slavery gave a name to the powerlessness of peasants facing landowners after the socialist leagues’ destruction; Mussolini’s insult then recast that political criticism as a test of personal courage. Missiroli accepted that test despite his lack of experience, while the duel’s course showed a contrast between his composure and Mussolini’s repeated, angry attacks.

The encounter also exposes the limits of symbolic resolution. The duel ended after Missiroli was wounded, but neither participant declared satisfaction, and the conditions Missiroli had been associated with remained part of the wider conflict. His appearance at Corso Sempione was not an alternative to political argument so much as its conversion into a contest of honor, staged amid continuing disputes over rural labor and fascist violence.
