French troops occupy Rome; the Roman Republic surrenders

Background. The Roman Republic was declared in February 1849 following Pope Pius IX's flight to Gaeta. Led by figures including Mazzini, the republic faced military intervention. French troops landed at Civitavecchia in April 1849, initiating a siege aimed at crushing the revolutionary government and re-establishing the Pope's temporal authority.

Military Campaign. General Charles Oudinot commanded the French expedition. Initial clashes occurred in April, with Republican forces under Garibaldi defeating a superior French army at Porta San Pancrazio. However, the French maintained the siege, preparing for a final assault to break the resistance and secure the city for the Papal States.

Surrender. On 30 June 1849, the Roman Assembly met and debated three options: surrender, continuing to fight in the streets, or retreating from Rome to continue resistance from the Apennine Mountains. The Republic's resistance ended not through an Assembly surrender decision but through a truce negotiated on 1 July and Garibaldi's withdrawal with some 4,000 troops on 2 July, after which French troops entered Rome on 3 July and reestablished the Holy See's temporal power.

Occupation. A truce was negotiated on 1 July, followed by Garibaldi's withdrawal from Rome on 2 July. French troops entered the city on 3 July, reestablishing the Holy See's temporal power. This occupation marked the definitive end of the Roman Republic's military resistance and the restoration of Papal authority.
