Crimean Peninsula in the context of "Annexation of Crimea by the Russian Empire"

Yalta (Ukrainian and Russian: Ялта) is a resort city on the south coast of the Crimean Peninsula surrounded by the Black Sea. It serves as the administrative center of Yalta Municipality, one of the regions within Crimea. Yalta, along with the rest of Crimea, is internationally recognised as part of Ukraine, and is considered part of the Autonomous Republic of Crimea. However, it is controlled de facto by Russia, which annexed Crimea in 2014 and regards the town as part of the Republic of Crimea. According to the most recent census, its population was 76,746 (2014 Census).

The city is located on the site of the ancient Greek colony of Yalita (Greek: Γιαλός, romanized: Gialós [ʝaˈlos̠]). It is said to have been founded by Greek settlers who were looking for a safe shore on which to land. It is situated on a deep bay facing south towards the Black Sea, surrounded by the mountain range Ai-Petri. It has a humid subtropical climate and is surrounded by numerous vineyards and orchards.

The Syvash or Sivash (Ukrainian and Russian: Сива́ш; Crimean Tatar: Sıvaş, Сываш, lit. 'dirt'), also known as the Putrid Sea or Rotten Sea (Russian: Гнило́е Мо́ре, romanized: Gniloye More; Ukrainian: Гниле́ Мо́ре, romanized: Hnyle More; Crimean Tatar: Çürük Deñiz), is a large area of shallow lagoons on the western edge of the Sea of Azov. Separated from the sea by the narrow Arabat Spit, the water of the Syvash covers an area of around 2,560 km (990 sq mi) and the entire area spreads over about 10,000 km (3,900 sq mi). The Henichesk Strait is its eastern connection to the Sea of Azov. The Syvash borders the northeastern coast of the main Crimean Peninsula. The central and eastern Syvash were registered as wetlands of Ukraine under the Ramsar Convention. Since the 2022 Russian invasion of Ukraine, the entire Syvash has been occupied by Russia.

Greek Crimea concerns the ancient Greek settlements on the Crimean Peninsula. Greek city-states first established colonies along the Black Sea coast of Crimea in the 7th or 6th century BC. Several colonies were established in the vicinity of the Kerch Strait, then known as the Cimmerian Bosporus. The density of colonies around the Cimmerian Bosporus was unusual for Greek colonization and reflected the importance of the area. The majority of these colonies were established by Ionians from the city of Miletus in Asia Minor. By the mid-1st century BC the Bosporan Kingdom became a client state of the late Roman Republic, ushering in the era of Roman Crimea during the Roman Empire.

The Crimean Peninsula (at the time known as Taurica) was under partial control of the Roman Empire during the period of 47 BC to c. 340 AD. The territory under Roman control mostly coincided with the Bosporan Kingdom (although under Nero, from 62 to 68 AD; it was briefly attached to the Roman Province of Moesia Inferior).Rome lost its influence in Taurica in the mid third century AD, when substantial parts of the peninsula fell to the Goths, but at least nominally the kingdom survived until the 340s AD. The Eastern Roman Empire, the eastern part of the Roman Empire that survived the loss of the western part of the empire, later regained Crimea under Justinian I. The Byzantine Empire controlled portions of the peninsula well into the Late Middle Ages.

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.

Several different governments controlled the Crimean Peninsula during the period of the Soviet Union, from the 1920s to 1991. The government of Crimea from 1921 to 1936 was the Crimean Autonomous Socialist Soviet Republic, which was an Autonomous Soviet Socialist Republic within the Russian Soviet Federative Socialist Republic (SFSR); the name was altered slightly to the Crimean Autonomous Soviet Socialist Republic from 1936 to 1945.

The Pechenegs (/ˈpɛtʃənɛɡ/) or Patzinaks, also known as Pecheneg Turks, were a semi-nomadic Turkic people from Central Asia who spoke the Pecheneg language. In the 9th and 10th centuries, the Pechenegs controlled much of the steppes of southeast Europe and the Crimean Peninsula. In the 9th century, the Pechenegs began a period of wars against Rus', and for more than two centuries launched raids into the lands of Rus', which sometimes escalated into full-scale wars.

Charax (Ancient Greek: Χάραξ, gen.: Χάρακος) is the largest Roman military settlement excavated in the Crimea. It was sited on a four-hectare area at the western ridge of Ai-Todor, close to the modern tourist attraction of Swallow's Nest.

The military camp was founded under Vespasian with the intention of protecting Chersonesus and other Bosporean trade emporiums from the Scythians. By the end of the 1st century AD, the Roman forces were evacuated from the peninsula. Several decades later the camp was restored by a vexillatio of the Legio I Italica; it hosted a detachment of the Legio XI Claudia at the end of the 2nd century. The camp was abandoned by the Romans in the mid-3rd century.
