Sardinia Day, also known as Sardinian People's Day, is observed on April 28 every year on the Italian island of Sardinia. This holiday commemorates the Sardinian Vespers, an uprising against the House of Savoy that took place in the late 18th century. The rebellion began on April 28, 1794, when locals in Cagliari responded to the arrest of two lawyers by capturing Piedmontese officials and soldiers. The uprising aimed to end feudalism and establish a republic in Sardinia, although it was ultimately suppressed by royal forces. In 1993, the Autonomous Region of Sardinia declared this date a national holiday, and it is marked by various festive events, particularly in Cagliari, with local schools typically closed for the day.
