Giuseppe Garibaldi is a historical figure known for his crucial role in unifying Italy in the 19th century. He was a leading figure in the Italian Risorgimento, a movement that aimed to consolidate the various independent states of the Italian Peninsula into a single nation. Garibaldi is famous for his daring military campaigns, including the Expedition of the Thousand, where he successfully led his volunteers, known as the "Red Shirts," to conquer Sicily and Naples. His efforts, along with collaborations with other leaders such as Count Cavour and King Victor Emmanuel II, culminated in the establishment of the Kingdom of Italy in 1861.
