Cause

Rome remained outside the newly unified Kingdom of Italy, still under Papal sovereignty and French protection. Garibaldi and Italian nationalists viewed Rome as essential to completing Italian unification, prompting a volunteer campaign to seize the city from Papal control.

Event

On November 3, 1867, Garibaldi's Italian volunteers clashed with combined French and Papal troops near the village of Mentana, north-east of Rome. The French-Papal forces, better armed and organized, repulsed the volunteers and secured a decisive victory on the battlefield.

Consequence

The defeat halted Garibaldi's attempt to take Rome and preserved Papal sovereignty over the city. The Papal States remained independent until 1870, when Italian forces finally captured Rome following the withdrawal of French troops during the Franco-Prussian War, completing Italian unification.
