In the 13th century, some Crimean port cities were controlled by the Venetians and by the Genovese, but the interior was much less stable, enduring a long series of conquests and invasions.
From 1853 to 1856, the strategic position of the peninsula in controlling the Black Sea meant that it was the site of the principal engagements of the Crimean War, where Russia lost to a French-led alliance.
During the Russian Civil War, Crimea changed hands many times and was where Wrangel's anti-Bolshevik White Army made their last stand in 1920, with tens of thousands of those who remained being murdered as part of the Red Terror.
The ASSR was downgraded to an oblast within the Russian SFSR in 1945 following the ethnic cleansing of the Crimean Tatars by the Soviet regime, and in 1954, Crimea was transferred to the Ukrainian SSR as part of celebrations of the 300th anniversary of the Treaty of Pereyaslav, called the "reunification of Ukraine with Russia" in the USSR.
[2] Archaeologists have found some of the earliest anatomically modern human remains in Europe in the Buran-Kaya caves in the Crimean Mountains (east of Simferopol).
[3][4] During the Last Glacial Maximum, along with the northern coast of the Black Sea in general, Crimea was an important refuge from which north-central Europe was re-populated after the end of the Ice Age.
The East European Plain during this time was generally occupied by periglacial loess-steppe environments, although the climate was slightly warmer during several brief interstadials and began to warm significantly after the beginning of the Late Glacial Maximum.
Early Iron Age Crimea was settled by two groups separated by the Crimean Mountains, the Tauri to the south and the Iranic Scythians in the north.
Taurians intermixed with the Scythians starting from the end of 3rd century BC were mentioned as "Tauroscythians" and "Scythotaurians" in the works of ancient Greek writers.
In the 3rd and 2nd centuries BC, Scythian Neapolis was a city "with a mixed Scythian-Greek population, strong defensive walls and large public buildings constructed using the orders of Greek architecture".
[citation needed] In 438 BC, the Archon (ruler) of Panticapaeum assumed the title of the King of Cimmerian Bosporus, a state that maintained close relations with Athens, supplying the city with wheat, honey and other commodities.
After the death of this sovereign, his son, Pharnaces II, was invested by Pompey with the Kingdom of the Cimmerian Bosporus in 63 BC as a reward for the assistance rendered to the Romans in their war against his father.
[citation needed] In the mid-10th century, the eastern area of Crimea was conquered by Prince Sviatoslav I of Kiev and became part of the Kievan Rus' principality of Tmutarakan.
A year later, Grand Prince Vladimir of Kiev accepted the hand of Emperor Basil II's sister Anna in marriage, and was baptized by the local Byzantine priest at Chersonesus, thus marking the entry of Rus' into the Christian world.
Throughout the ancient and medieval period the interior and north of Crimea was occupied by a changing cast of invading steppe nomads, such as the Tauri, Cimmerians, Scythians, Sarmatians, Crimean Goths, Anglo-Saxons,[18][19] Alans, Bulgars, Huns, Khazars, Kipchaks and Mongols.
A small enclave of Crimean Karaites, a people of Jewish descent practising Karaism who later adopted a Turkic language, formed in the 13th century.
The Treaty of Küçük Kaynarca signed in June 1774 forced the Sublime Porte to recognize the Tatars of the Crimea as politically independent, meaning that the Crimean Khans fell under Russian influence.
On 28 December 1783 the Sublime Porte negotiated a trade agreement with the Russian diplomat Bulgakov that recognised the loss of Crimea and other territories that had been held by the Khanate.
It has widely been noted that the causes, in one case involving an argument over a key, had never revealed a "greater confusion of purpose" but led to a war that stood out for its "notoriously incompetent international butchery".
The Crimean Tatars had to flee from their homeland en masse, forced by the conditions created by the war, persecution, and land expropriations.
The leaders of the Third Reich were anxious to conquer and colonize the fertile and beautiful peninsula as part of their policy of resettling the Germans in Eastern Europe at the expense of the Slavs.
In the Crimean campaign, German and Romanian troops suffered heavy casualties in the summer of 1941 as they tried to advance through the narrow Isthmus of Perekop linking Crimea to the Soviet mainland.
From 1 September 1942, the peninsula was administered as the Generalbezirk Krim (general district of Crimea) und Teilbezirk (and sub-district) Taurien by the Nazi Generalkommissar Alfred Eduard Frauenfeld (1898–1977), under the authority of the three consecutive Reichskommissare for the entire Ukraine.
In spite of heavy-handed tactics by the Nazis and the assistance of the Romanian and Italian troops, the Crimean mountains remained an unconquered stronghold of the native resistance (the partisans) until the day when the peninsula was freed from the occupying force.
Due to its enormous historical and symbolic meaning for the Russians, it became a priority for Stalin and the Soviet government to have it restored to its former glory within the shortest time possible.
[25]: 483 On 26 June of the same year Armenian, Bulgarian and Greek population was also deported to Central Asia, and partially to Ufa and its surroundings in the Ural mountains.
[72] At the same time Russian president Vladimir Putin discussed Ukrainian events with security service chiefs remarking that "we must start working on returning Crimea to Russia".
The United Nations General Assembly also rejected the referendum and annexation, adopting a resolution affirming the "territorial integrity of Ukraine within its internationally recognised borders".
[86][87] According to survey carried out by Pew Research Center in 2014, the majority of Crimean residents say they believed the referendum was free and fair (91%) and that the government in Kyiv ought to recognize the results of the vote (88%).
[100] In 2022, Russia conquered portions of Kherson Oblast, which allowed it to unblock the North Crimean canal by force, resuming water supply into Crimea.
