The Redshirts (Italian: Camicie rosse or Giubbe rosse), also called the Red Coats, are volunteers who followed the Italian patriot Giuseppe Garibaldi during his campaigns. The name derived from the colour of their shirts or loose-fitting blouses that the volunteers, usually called Garibaldini, wore in lieu of a uniform.
The force originated as the Italian Legion supporting the Colorado Party during the Uruguayan Civil War. The story is that Garibaldi was given red shirts destined for slaughterhouse workers. Later, during the wars of Italian unification, the Redshirts won several battles against the armies of the Austrian Empire, the Kingdom of Two Sicilies and the Papal States. Most notably, Garibaldi led his Redshirts in the Expedition of the Thousand of 1860, which concluded with the annexation of Sicily, Southern Italy, Marche, and Umbria to the Kingdom of Sardinia, which led to the creation of a unified Kingdom of Italy. His military enterprises in South America and Europe made Garibaldi become known as the "Hero of the Two Worlds".
