The Erlacherhof plot
From rebellious patricians and ammunition stashed in the city hall to a wave of arrests and a controversial trial – the Erlacherhof plot of 1832 was a turning point in the history of the canton of Bern.
Political power shift
In the 1830s, a liberal constitution led to a power shift in the cantons, with communes now giving voting rights to all citizens rather than merely to a privileged class. This resulted in the urban elites losing control of their territories. This was also the case in Bern, where electoral communes sprang up throughout the canton. Yet the old elites fought to retain the old order and thus their power and wealth. This led to a division, which still exists today.


Karl von Lentulus was tasked with the procurement of weapons. The 26-year-old captain from Bern had served in the French forces up until 1830, so could draw on his lengthy military experience and extensive network in military circles. After the Swiss regiments in the Netherlands were dissolved and the troops serving in France were discharged at the end of the July Revolution, there were plenty of unemployed soldiers. In the summer of 1832, von Lentulus started organising gatherings at which he would actively seek to recruit members for the new patrician civic guard. The canton of Bern seemed to be sliding headlong into a civil war.
The stockpiling of ammunition didn’t remain a well-guarded secret for long. Rumours soon started to spread in Bern’s backstreets about plans for a revolution being hatched at the Erlacherhof. There was talk of soldiers, rifles and cannons ready for deployment. This provoked the cantonal government to actively intervene in late August. Two hundred volunteers were hastily recruited and summoned to the city of Bern. Additional troops, equipped with cannons, were redeployed to Burgdorf, Biel, Thun and Interlaken. Arrests were made throughout the canton, with almost 300 people imprisoned – both recruiters and recruits from the patrician group.
An arrest warrant was even issued for von Lentulus, but he managed to flee abroad. Meanwhile, in the city itself, a sniper division was ordered to search the Erlacherhof. According to the report by the officer in charge, the hidden cartridges were discovered in the side wall, next to the Bubenbergtor city gate. On 3 September 1832, the members of the Siebnerkommission were arrested for high treason.
Separation of powers undermined
The investigations dragged on for months, which allowed the government to fill the cantonal supreme court with loyalists. An initial verdict of 1837 was not enforced as it was deemed too lenient. It was December 1839 by the time the court handed down its final judgments: 86 people were acquitted, and 207 were given monetary penalties or custodial sentences up of up to ten years. Of the six remaining members of the Siebnerkommission, Emanuel von Fischer and Karl Tscharner were each sentenced to two years in prison, and the others to one. Thorberg Castle was converted into a prison for the high-profile inmates – and they had to cover the costs of board and lodging themselves.
The Erlacherhof plot put an end to the influence of the patriciate in the canton of Bern once and for all, paving the way for a more democratic political system. It also influenced reform movements in other cantons.
