Crimea

Crimea[b] (/kraɪˈmiːə/ ⓘ kry-MEE-ə) is a peninsula in Eastern Europe, on the northern coast of the Black Sea, almost entirely surrounded by the Black Sea and the smaller Sea of Azov... After Ukrainian (Ukraine) independence in 1991, the central government and the Republic of Crimea clashed, with the region being granted more autonomy. The Soviet fleet in Crimea was also in contention, but a 1997 treaty allowed Russia to continue basing its fleet in Sevastopol. In 2014, the peninsula was occupied by Russian forces and annexed by Russia, but most countries recognise Crimea as Ukrainian territory. https://en.wikipedia.org/wiki/Crimea
