Which island does this flag fly over?

sicily isnt a country.......

In 1848, a revolution took place which separated Sicily from Naples and gave it independence. In 1860 Giuseppe Garibaldi and his Expedition of the Thousand took control of Sicily and the island became a part of the Kingdom of Italy. In 1946, Italy became a republic and Sicily became an autonomous region.

Player #27228753, Sicily is in southern Italy, North of Malta and in the middle of the Mediterranean Sea

it does not say what country it says what island,

I thought it was the Isle of Mann but it wasn't in the question.
