San Giovanni in Persiceto is presented through Decima, a small, remote rural district where conflict over agricultural labor turned into a massacre. The deaths intensified the political crisis in the province and helped prompt local bourgeois groups to organize in the name of self-defense.

Decima and the Agricultural Conflict

The confrontation took place during a rally about the collective farm agreement, organized amid a struggle over the terms of agricultural work. Sigismondo Campagnoli, sent by the Bologna Chamber of Labor, spoke about the agrarian issue and called for revolution. When the public-order brigadier pulled him down from the platform, Pietro Comastri took his place; although he initially promised a more restrained address, he too turned to revolutionary language. The officer faced twenty Carabinieri and a crowd of about 1,500 farmhands, leaving the dispute poised between an attempted intervention and a mass gathering.

The Escalation and Its Aftermath

A bottle thrown during the confrontation struck the farmhouse wall, and a few drops of blood from the deputy inspector’s temple became the immediate trigger for violence. The crowd surged forward; the Carabinieri, positioned with their backs to the wall, opened fire without waiting for an order. The exchange lasted only moments, but left eight people dead and about thirty injured. Nearly all the dead had been shot from behind, and Campagnoli was killed after the firing began. The account’s emphasis on this abrupt turn—from a rally over farm labor to lethal force—makes the massacre at Decima a local rupture with consequences well beyond the gathering itself.

The deaths brought the province to a three-day general strike, suspending public and private services as workers withdrew their labor. They also helped drive farmers, manufacturers, merchants, professionals, public employees, and homeowners to organize independently. On April 8, a meeting promoted by the Chamber of Commerce established the Bolognese Association of Social Defense; a week later, its delegation told Prime Minister Nitti that the state had failed to confront socialist violence and declared its readiness to act in the name of self-defense. San Giovanni in Persiceto thus enters the narrative not only as the site of a massacre, but as the point at which rural conflict helped galvanize a broader counter-mobilization.

The Rural Setting in the Po Valley

Decima’s confrontation belonged to a wider struggle over who controlled agricultural work across the Po Valley. In Emilia, socialists controlled 223 of 280 municipalities, while peasant leagues regulated hiring, work shifts, threshing operations, and seed supplies. Farmhands averaged only 120 days of work a year, making the terms of employment a matter of survival during idle months. The conflict at San Giovanni in Persiceto therefore took place within a rural economy where labor rules had become a direct contest over livelihood and authority.

The strain persisted beyond the rally. In August 1920, harvested grain lay unthreshed and rotting in the fields, while farmworkers’ actions against landowners extended into the care of livestock. These conditions show the agricultural conflict as more than a dispute over a single agreement: it reached into production, employment, and the daily operation of farms. Decima’s place in the narrative is sharpened by that regional context, where social antagonism was embedded in the management of land and labor.

A Remote District at the Center of the Narrative

The account locates the massacre in Decima, a small, remote countryside district of San Giovanni in Persiceto, rather than in a major urban setting. Its description as an apparently insignificant place sharpens the contrast between the locality’s obscurity and the political weight the narrative assigns to what happened there. San Giovanni in Persiceto thus marks how the conflict over agricultural labor reached beyond the city and made the rural landscape itself a site of national political rupture.
