Bavaria enters the account of the Holy Roman Empire through a pointed case of coercion disguised as enforcement. Its duke is appointed to carry out an imperial ban against Donauwörth, but uses the assignment to pursue an old territorial claim and annex the city. The episode makes the danger of the Empire’s military system concrete: authority delegated to enforce common rules can become an instrument of a member’s private expansion.

Setting and Imperial Enforcement

The case arises within an Empire whose weak central government had tried to maintain order by dividing its territory into circles, or districts, and charging them with military enforcement against members that defied the law. The arrangement was meant to address the difficulty of securing justice among sovereign subjects. In practice, the circles either failed to carry out their commissions or did so with the destruction and violence of civil conflict; sometimes an entire circle defaulted, aggravating the disorder it was meant to correct.

Donauwörth was a free imperial city in the circle of Swabia. The Abbe de St. Croix held certain reserved immunities there, and, on public occasions, people of the city committed abuses against him in the exercise of those privileges. The Empire responded by placing the city under its ban. That judgment supplied the legal occasion for a military expedition, but did not ensure that the expedition would serve the common authority rather than its commander’s interests.

The Duke’s Seizure of Donauwörth

The Duke of Bavaria, although director of another circle, obtained the appointment to enforce the ban. He appeared before Donauwörth with ten thousand troops. The scale of the force turned a disciplinary measure into a demonstration of overwhelming power, while the duke’s position as a commander from outside the city’s own circle underscored how imperial enforcement could be redirected by a powerful prince.

The account presents the duke’s territorial purpose as existing from the beginning: he revived an obsolete claim that his ancestors had allowed the city to be separated from their territory. Using enforcement of the imperial ban as his pretext, he took possession of Donauwörth in his own name, disarmed and punished its inhabitants, and annexed the city to his domains. The sequence matters: the Empire’s sanction creates the opening, but the duke’s separate claim determines the result. Rather than restoring the city to an impartial common order, the mission enlarges Bavaria.

Political Significance

The episode serves as a practical example of the defects of military coercion in a fragmented political system. A central authority may issue a decision, yet depend on a member’s forces to execute it; when that member has its own interests, the common commission can be converted into private advantage. In Donauwörth, enforcement does not merely fail to restrain a powerful actor: it furnishes him with the means and occasion to expand his territory.

Bavaria’s role therefore illustrates the difference between possessing a formal mandate and acting for the public good. The account uses the seizure to show how weak institutions invite powerful members to exploit common procedures, deepening the disorder those procedures were designed to remedy. The city’s annexation is not presented as a reform of imperial government, but as evidence that its coercive machinery could intensify the instability of the union.
