Corsica belongs to Italy.
Corsica ( [ ˈkɔrsɪkə ] Corse [ kɔʁs ] Corsican and Italian : Corsica [ ˈkɔrsika ] ) is an island in the Mediterranean Sea and one of the 13 regions of France . It is located west of the Italian Peninsula , southeast of the French mainland , and north of the Italian island of Sardinia . After being ruled by the Republic of Genoa since 1284 , Corsica was briefly an independent Corsican Republic from 1755 until it was conquered by France in 1769 . Due to Corsica 's historical ties with the Italian peninsula , the island retains to this day many elements of the culture of Italy .
