Crimea (or the Tauric Peninsula, as it was called from
antiquity until the
early modern period) has historically been at the boundary between the
classical world and the
Pontic–Caspian steppe. Its southern fringe was colonised by the
Greeks, the
Persians, the
Romans, the
Byzantine Empire, the
Crimean Goths, the
Genoese and the
Ottoman Empire, while at the same time its interior was occupied by a changing cast of invading
steppe nomads and empires, such as the
Cimmerians,
Scythians,
Sarmatians,
Goths,
Alans,
Bulgars,
Huns,
Khazars,
Kipchaks,
Mongols and the
Golden Horde. Crimea and adjacent territories were united in the
Crimean Khanate during the 15th to 18th century.
In
1783, Crimea was
annexed by the Russian Empire as the result of the
Russo-Turkish War (1768–1774). Following the
Russian Revolution of 1917, Crimea became an
autonomous republic within the
Russian Soviet Federative Socialist Republic in the
USSR. During
World War II, Crimea was downgraded to the
Crimean Oblast after its entire indigenous population, the
Crimean Tatars,
were deported to Central Asia, an act recognized as a genocide by Ukraine and three other countries. In 1954, it was
transferred to the Ukrainian SSR from the
Russian SFSR.
[5]With the
collapse of the Soviet Union, Ukraine was reestablished as an independent state in
1991, and most of the peninsula was reorganized as the
Autonomous Republic of Crimea, while the city of
Sevastopol retained its special status within Ukraine. The
1997 Partition Treaty on the Status and Conditions of the Black Sea Fleet partitioned the former Soviet Black Sea Fleet and allowed Russia to continue basing its fleet in Crimea: both the
Ukrainian Naval Forces and Russian's Black Sea Fleet were to be headquartered in Sevastopol. Ukraine extended Russia's lease of the naval facilities under the
2010 Kharkiv Pact in exchange for further discounted
natural gas.
In
February 2014, following the
2014 Ukrainian revolution that ousted the
Ukrainian President,
Viktor Yanukovych,
Russia annexed Crimea after a military intervention by pro-Russian separatists and
Russian Armed Forces. A controversial
Crimea-wide referendum,
illegal under the Ukrainian and Crimean constitutions, was held on the issue of reunification with Russia; its official results showed over 90% support for reunification, however, the vote was boycotted by many loyal to Ukraine and declared illegitimate by Western governments and the United Nations. Russia formally
annexed Crimea on
18 March 2014, incorporating the
Republic of Crimea and the
federal city of
Sevastopol as the 84th and 85th
federal subjects of Russia. The
status of Crimea is disputed. It is
claimed by Ukraine and recognized as Ukrainian by the United Nations and most other countries.
