Sardinia's Day, also known as Sardinian people's Day, is a holiday in Sardinia commemorating the Sardinian Vespers occurring in 1794–96.

The French expedition to Sardinia was a short military campaign fought in 1793 in the Mediterranean Sea in the first year of the War of the First Coalition, during the French Revolutionary Wars. The operation was the first offensive by the new French Republic in the Mediterranean during the conflict, and was directed at the island of Sardinia, part of the Kingdom of Sardinia. Sardinia was neutral at the time, but immediately joined the anti-French coalition. The operation was a failure, with attacks directed at Cagliari in the south and La Maddalena in the north both ending in defeat.
