Who are Corsicans?
Corsicans are the people of Corsica, a Mediterranean island between France, Italy, Sardinia, and the Ligurian Sea. Corsican history is shaped by prehistoric island settlement, Roman rule, medieval Pisa and Genoa, mountain communities, maritime links, French rule, and a strong regional island identity.
French is the official language, while Corsican is a Romance language closely related to central Italian and Tuscan varieties. Corsica's geography makes it an island population with close cultural and historical links to Italy as well as France.
As a genetic reference, Corsican is useful for comparison with Italian Carloforte Ligurian, Tuscan, Ligurian, Lombard, Emilian, Romagnol, Swiss Italian, Sardinian, and other western Mediterranean references.
