Crimean Khanate in the context of "Autonomous Republic of Crimea"

Crimea (/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. The Isthmus of Perekop connects the peninsula to Kherson Oblast in mainland Ukraine. To the east, the Crimean Bridge, constructed in 2018, spans the Strait of Kerch, linking the peninsula with Krasnodar Krai in Russia. The Arabat Spit, located to the northeast, is a narrow strip of land that separates the Syvash lagoons from the Sea of Azov. Across the Black Sea to the west lies Romania and to the south is Turkey. The population is 2.4 million, and the largest city is Sevastopol. The region, internationally recognised as part of Ukraine, has been under Russian occupation since 2014.

Called the Tauric Peninsula until the early modern period, Crimea has historically been at the boundary between the classical world and the steppe. Greeks colonised its southern fringe and were absorbed by the Roman and Byzantine Empires and successor states while remaining culturally Greek. Some cities became trading colonies of Genoa, until conquered by the Ottoman Empire. Throughout this time the interior was occupied by a changing cast of steppe nomads, coming under the control of the Golden Horde in the 13th century from which the Crimean Khanate emerged as a successor state. In the 15th century, the Khanate became a dependency of the Ottoman Empire. Lands controlled by Russia and Poland-Lithuania were often the target of slave raids during this period. In 1783, after the Russo-Turkish War (1768–1774), the Russian Empire annexed Crimea. Crimea's strategic position led to the 1854 Crimean War and many short lived regimes following the 1917 Russian Revolution. When the Bolsheviks secured Crimea, it became an autonomous soviet republic within the Russian Soviet Federative Socialist Republic. It was occupied by Germany during World War II. When the Soviets retook it in 1944, Crimean Tatars were ethnically cleansed and deported under the orders of Joseph Stalin, in what has been described as a cultural genocide. Crimea was downgraded to an oblast in 1945. In 1954, the USSR transferred the oblast to the Ukrainian Soviet Socialist Republic on the 300th anniversary of the Pereyaslav Treaty in 1654.

The recorded history of the Crimean Peninsula, historically known as Tauris, Taurica (Greek: Ταυρική or Ταυρικά), and the Tauric Chersonese (Greek: Χερσόνησος Ταυρική, "Tauric Peninsula"), begins around the 5th century BCE when several Greek colonies were established along its coast, the most important of which was Chersonesos near modern-day Sevastopol, with Scythians and Tauri in the hinterland to the north. The southern coast gradually consolidated into the Bosporan Kingdom which was annexed by Pontus and then became a client kingdom of Rome (63 BC – 341 AD). The south coast remained Greek in culture for almost two thousand years including under Roman successor states, the Byzantine Empire (341–1204), the Empire of Trebizond (1204–1461), and the independent Principality of Theodoro (ended 1475). 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. In the medieval period, it was partially conquered by Kievan Rus' whose prince Vladimir the Great was baptised at Chersonesus Cathedral, which marked the beginning of the Christianization of Kievan Rus'. During the Mongol invasion of Europe, the north and centre of Crimea fell to the Mongol Golden Horde, and in the 1440s the Crimean Khanate formed out of the collapse of the horde but quite rapidly itself became subject to the Ottoman Empire, which also conquered the coastal areas which had kept independent of the Khanate. A major source of prosperity in these times was frequent raids into Russia for slaves for the Crimean slave trade.

In 1774, the Ottoman Empire was defeated by Catherine the Great. After two centuries of conflict, the Russian fleet had destroyed the Ottoman navy and the Russian army had inflicted heavy defeats on the Ottoman land forces. The ensuing Treaty of Küçük Kaynarca forced the Sublime Porte to recognize the Tatars of the Crimea as politically independent. Catherine the Great's incorporation of the Crimea in 1783 from the defeated Ottoman Empire into the Russian Empire increased Russia's power in the Black Sea area. The Crimea was the first Muslim territory to slip from the sultan's suzerainty. The Ottoman Empire's frontiers would gradually shrink, and Russia would proceed to push her frontier westwards to the Dniester. 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.

Between 1441 and 1774, the Crimean Khanate and the Nogai Horde conducted slave raids throughout lands primarily controlled by Russia and Poland–Lithuania. Concentrated in Eastern Europe, but also stretching to the Caucasus and parts of Central Europe, these raids were often supported by the Ottoman Empire and involved the transportation of European men, women, and children to the Muslim world, where they were put on the market and sold as part of the Crimean slave trade and the Ottoman slave trade. The regular abductions of people over the course of numerous incursions by the Crimeans and the Nogais greatly drained Eastern Europe's human and economic resources, consequently playing an important role in the emergence of the semi-militarized Cossacks, who organized retaliatory campaigns against the raiders and their Ottoman backers.

Trading posts in Crimea had previously been established by the Genoese and the Venetians to facilitate earlier Western European slave routes. The Crimean–Nogai raids largely targeted the "Wild Fields" of the Pontic–Caspian steppe, which extends about 800 kilometres (500 mi) north of the Black Sea and which now contains the majority of the combined population of southeastern Ukraine and southwestern Russia.

The Russian Empire formally annexed the Crimean Khanate on 19 April [O.S. 8 April] 1783, following a decade-long campaign of intervention in the Crimean Peninsula. Russia aimed to control the Black Sea and end raids by Crimean slavers into its territory. To accomplish this, the Russians waged a series of wars against the Ottoman Empire and its Crimean vassal state, culminating in victory in the 1768–1774 Russo-Turkish War. The Treaty of Küçük Kaynarca, signed in 1774, granted the Crimean Khanate nominal independence from the Ottomans under Russian influence. In subsequent years, Russia would intervene widely in Crimean affairs, provoking a series of revolts by the Crimean Tatars, while the Ottomans watched in ambivalence. Crimea was finally annexed by Russia on 19 April 1783, after Russian imperial advisor Prince Grigory Potemkin encouraged Empress Catherine the Great to dissolve the khanate and formally claim its territory. The annexation ended the centuries-long Crimean slave trade. Under Russian administration, the former khanate was subjected to a long-term policy of de-Tatarisation. Tatar property was confiscated, and Russians were encouraged to settle in the region, sparking waves of Tatar emigration.

Catherine II (born Princess Sophia Augusta Frederica, Russian: Екатерина Алексеевна Романова; 2 May 1729 – 17 November [O.S. 6 November] 1796), commonly known as Catherine the Great, was the reigning Empress of Russia from 1762 to 1796. She came to power after a coup d'etat against her husband, Peter III. Her long reign helped Russia thrive under a golden age under the Enlightenment. This renaissance led to the founding of many new cities, universities, and theatres, along with large-scale immigration from the rest of Europe and the recognition of Russia as one of the great powers of Europe.

After overthrowing and possibly assassinating her husband and her subsequent rule of the Russian Empire, Catherine often relied on noble favourites such as Count Grigory Orlov and Grigory Potemkin. Assisted by highly successful generals such as Alexander Suvorov and Pyotr Rumyantsev and admirals such as Samuel Greig and Fyodor Ushakov, she governed at a time when the Russian Empire was expanding rapidly by conquest and diplomacy. In the west, she installed her former lover to the throne of Poland, which was eventually partitioned. In the south, the Crimean Khanate was annexed following victories over the Bar Confederation and the Ottoman Empire in the Russo-Turkish War. With the support of Great Britain, Russia colonised the territories of New Russia along the coasts of the Black and Azov Seas. In the east, Russians became the first Europeans to colonise Alaska, establishing Russian America.

The Black Sea slave trade trafficked people across the Black Sea from Eastern Europe and the Caucasus to slavery in the Mediterranean and the Middle East. The Black Sea slave trade was a center of the slave trade between Europe and the rest of the world from antiquity until the 19th century. One of the major and most significant slave trades of the Black Sea region was the trade of the Crimean Khanate, known as the Crimean slave trade.

The Black Sea is situated in a region historically dominated by the margins of empires, conquests and major trade routes between Europe, the Mediterranean and Central Asia, notably the Ancient Silk Road, which made the Black Sea ideal for a slave trade of war captives sold along the trade routes.
