Giuseppe Garibaldi’s entry into Naples marked a significant event in Italy's struggle for unification. Following the successful expedition in Sicily, where he gained widespread support from local populations, Garibaldi sought to extend his influence into the mainland. The year was crucial in the context of Italian nationalism, with various regions striving for independence from foreign rule and local monarchies. Garibaldi’s Redshirts, comprising a mix of workers, soldiers, and patriots, marched northwards from their Sicilian stronghold toward Naples, energizing the movement for a united Italy.

Upon arriving in Naples, Garibaldi was greeted with enthusiastic celebrations, symbolizing the desire for change among the Neapolitans. The atmosphere in the city was charged with hope and rebellion, as the citizens welcomed Garibaldi as a liberator from the oppressive rule of the Bourbon monarchy. His arrival was seen as a turning point, encouraging many to join his cause and pushing for a political transition toward unity under a republic or a constitutional monarchy. On this occasion, Garibaldi famously took a less formal approach to governance, choosing to emphasize the power of the people in fighting for their nation.

The events in Naples played a crucial role as they catalyzed broader support for unification across Italy. With Garibaldi at the forefront, the unification efforts received international attention, drawing further assistance from other nationalist factions and Italian expatriates. This exhilarating moment not only reinforced Garibaldi's reputation as a national hero but also provided a template for organized national movements in Italy, eventually leading to the proclamation of the Kingdom of Italy in 1861. The momentum gained in Naples ultimately contributed to the consolidation of Italy’s various states, leading to a more unified political and national identity by the late 19th century.
