In March 1821, Austrian forces led by General Johann Maria Philipp Frimont entered Naples, effectively ending the constitutional regime established by King Ferdinand I. Following the defeat of Neapolitan troops at Rieti, Frimont's army occupied the capital, restoring Ferdinand's absolute authority. This intervention, facilitated by Metternich's diplomacy, marked the collapse of the Neapolitan constitutional experiment and reinforced Austrian influence in the region.

Background and detail

Background. King Ferdinand I had been forced to sign a constitution in July 1820 following a military revolt. The Troppau Protocol of 1820, signed by Austria, Prussia, and Russia, provided the framework for intervention. Metternich persuaded Ferdinand to allow an Austrian army to march into Naples to restore order, setting the stage for military action against the constitutional government.

Military Campaign. Neapolitan forces under General Pepe failed to defend the defiles of the Abruzzi and were defeated at the Battle of Rieti on 7 March 1821. This defeat cleared the path for Austrian forces under Frimont, who had previously commanded at Venice, to advance into the Neapolitan capital without significant resistance.

Restoration of Authority. Frimont's army victoriously entered Naples by 24 March 1821, ending the constitutional regime. Count Charles-Louis de Ficquelmont was appointed as the Austrian ambassador, practically administering the country and strengthening Austrian influence over Neapolitan elites, ensuring the restoration of Ferdinand's absolute power.
