Most notably, Garibaldi led his Redshirts in the Expedition of the Thousand of 1860, which concluded with the annexation of Sicily, Southern Italy, and Umbria to the Kingdom of Sardinia, which led to the creation of the newly-unified Kingdom of Italy. His military enterprises in South America and Europe made Garibaldi become known as the "Hero of the Two Worlds". Garibaldi's son Ricciotti led some Redshirt volunteers that fought with the army of Greece during the Greco-Turkish War and the First Balkan War. The term Redsirts and Garibaldino were later used to describe the Italian volunteers who fought for France in 1914, the Garibaldi Legion, and the Italian volunteers who fought for the Republicans in the Spanish Civil War and the Italian antifascist partisans in the Second World War. The Redshirts were very popular and influenced many armies worldwide. For example, during the American Civil War, the Union's Garibaldi Guard and its Confederate counterpart, the Garibaldi Legion, wore red shirts as a part of their uniforms. The Garibaldi shirt also became a popular type of clothing. According to A Cultural History of the Modern Age: The Crisis of the European Soul, "For a considerable time Garibaldi was the most famous man in Europe, and the red shirt, la camicia rossa, became the fashion for ladies, even outside Italy".
