Giuseppe Garibaldi is remembered for advocating for the unification of Italy in the 19th century. A key figure in the Italian Risorgimento, he led military campaigns that were instrumental in the unification process. His famous expedition, known as the "Thousand" or "Expedition of the Thousand," in 1860, saw him capture Sicily and Naples, significantly advancing the cause of Italian unification. Garibaldi was revered as a national hero and often referred to as the "Hero of Two Worlds" for his involvement in revolutionary activities both in Italy and abroad. His efforts collectively contributed to the establishment of a unified Italy by 1871.
