Note
1: Northern Cyprus is a Turkish-supported de facto state in the north part
of the island. It is not recognized by the international community. Cyprus also
hosts two British bases that are under the sovereignty of the U.K. rather than
Cyprus.
Special case:
Cuba: The Cuban government does not administer the whole
island of Cuba. The United States retains control over the Guantanamo
Bay base, at the southeastern end of the island. The border of the base also cuts across
Flamingo Cay, leaving about 60% of the small island under American control.
Former:
Vozrozhdeniya, an island in
the Aral Sea between Uzbekistan and Kazakhstan, had been the 8th largest
divided island, at about 900 sq miles / 2,300, but the shrinking of the sea
caused it to join to the mainland between June 2000 and June 2001.
It is likely
that there are small islands on the U.S.-Canadian border and in Scandinavia
that have been omitted from this list.
