To which country does the Mediterranean island Corsica belong?

Explanation

Corsica is a French island in the Mediterranean Sea with around 300,000 inhabitants and an area of 8680 km2. Since 1991, the island has been a semi-autonomous region. The regional administrative capital is Ajaccio. The island is mountainous and not particularly suited for agriculture. Therefore, tourism is very important for the local economy. There are several associations and parties working for Corsican independence or self-rule.
