Russia in the context of Romanov

The Black Sea is a marginal sea lying between Europe and Asia, east of the Balkans, south of the East European Plain, west of the Caucasus, and north of Anatolia. It is bounded by Bulgaria, Georgia, Romania, Russia, Turkey, and Ukraine. The Black Sea is supplied by major rivers, principally the Danube, Dnieper and Dniester. Consequently, while six countries have a coastline on the sea, its drainage basin includes parts of 24 countries in Europe.

The Black Sea, not including the Sea of Azov, covers 436,400 km (168,500 sq mi), has a maximum depth of 2,212 m (7,257 ft), and a volume of 547,000 km (131,000 cu mi).Most of its coasts ascend rapidly.These rises are the Pontic Mountains to the south, bar the southwest-facing peninsulas, the Caucasus Mountains to the east, and the Crimean Mountains to the mid-north.In the west, the coast is generally small floodplains below foothills such as the Strandzha; Cape Emine, a dwindling of the east end of the Balkan Mountains; and the Dobruja Plateau considerably farther north. The longest east–west extent is about 1,175 km (730 mi). Important cities along the coast include (clockwise from the Bosporus) the northern suburbs of Istanbul, Burgas, Varna, Constanța, Odesa, Yalta, Kerch, Yevpatoria, Sevastopol, Novorossiysk, Sochi, Poti, Batumi, Rize, Trabzon, Ordu, Simferopol, Samsun and Zonguldak.

Europe is a continent located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere. It is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, the Mediterranean Sea to the south, and Asia to the east. Europe shares the landmass of Eurasia with Asia, and of Afro-Eurasia with both Africa and Asia. Europe is commonly considered to be separated from Asia by the watershed of the Ural Mountains, the Ural River, the Caspian Sea, the Greater Caucasus, the Black Sea, and the Turkish straits.

Europe covers approx. 10,186,000 square kilometres (3,933,000 sq mi), or 2% of Earth's surface (6.8% of Earth's land area), making it the second-smallest continent (using the seven-continent model). Politically, Europe is divided into about fifty sovereign states, of which Russia is the largest and most populous, spanning 39% of the continent and comprising 15% of its population. Europe had a total population of about 745 million (about 10% of the world population) in 2021; the third-largest after Asia and Africa. The European climate is affected by warm Atlantic currents, such as the Gulf Stream, which produce a temperate climate, tempering winters and summers, on much of the continent. Further from the sea, seasonal differences are more noticeable producing more continental climates.

The Caucasus (/ˈkɔːkəsəs/) or Caucasia (/kɔːˈkeɪʒə/) is a region spanning Eastern Europe and Western Asia. It is situated between the Black Sea and the Caspian Sea, comprising parts of Southern Russia, Georgia, Armenia, and Azerbaijan. The Caucasus Mountains, including the Greater Caucasus range, have conventionally been considered as a natural barrier between Europe and Asia, bisecting the Eurasian landmass. Mount Elbrus, Europe's highest mountain, is situated in the Western Caucasus area of Russia. On the southern side, the Lesser Caucasus includes the Javakheti Plateau and the Armenian highlands.

The Caucasus is divided into the North Caucasus and South Caucasus, although the Western Caucasus also exists as a distinct geographic space within the North Caucasus. The Greater Caucasus mountain range in the north is mostly shared by Russia and Georgia as well as the northernmost parts of Azerbaijan. The Lesser Caucasus mountain range in the south is mostly located on the territory of southern Georgia, Armenia, and Azerbaijan. The region is known for its linguistic diversity: aside from Indo-European and Turkic languages, the Kartvelian, Northwest Caucasian, and Northeast Caucasian language families are indigenous to the area.

Southern Russia or the South of Russia (Russian: Юг России, IPA: [juk rɐˈsʲiɪ]) is a colloquial term for the southernmost geographic portion of European Russia. The term is generally used to refer to the region of Russia's Southern Federal District and North Caucasian Federal District.

The term is informal and does not conform to any official areas of the Russian Federation as designated by the Russian Classification on Objects of Administrative Division (OKATO).

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 Sea of Okhotsk is a marginal sea of the northwestern Pacific Ocean. It is located between Russia's Kamchatka Peninsula on the east, the Kuril Islands on the southeast, Japan's island of Hokkaido on the south, the island of Sakhalin along the west, and a stretch of eastern Siberian coast along the west and north. Its northeast corner is the Shelikhov Gulf. The sea is named for the port of Okhotsk, itself named for the Okhota River.

A subregion is a part of a larger geographical region or continent. Cardinal directions are commonly used to define subregions. There are many criteria for creating systems of subregions; this article is focusing on the United Nations geoscheme, which is a changing, constantly updated, UN tool based on specific political geography and demography considerations relevant in UN statistics.

East Thrace or Eastern Thrace, also known as Turkish Thrace or European Turkey, is the part of Turkey that is geographically in Southeast Europe. Turkish Thrace accounts for 3.03% of Turkey's land area and 15% of its population. The largest city is Istanbul, which straddles the Bosporus between Europe and Asia. East Thrace is of historic importance as it is next to a major sea trade corridor and constitutes what remains of the once-vast Ottoman region of Rumelia. It is currently also of specific geostrategic importance because the sea corridor, which includes two narrow straits, provides access to the Mediterranean Sea from the Black Sea for the navies of five countries: Russia, Ukraine, Romania, Bulgaria, and Georgia. The region also serves as a future connector of existing Turkish, Bulgarian, and Greek high-speed rail networks.Due to the guest worker agreement with Turkey and Germany, some Turks in Germany originally come from Eastern Thrace, mostly from the Kırklareli Province.

Old Great Bulgaria (Medieval Greek: Παλαιά Μεγάλη Βουλγαρία, Palaiá Megálē Voulgaría), also often known by the Latin names Magna Bulgaria and Patria Onoguria ("Onogur land"), was a 7th-century Turkic nomadic empire formed by the Onogur-Bulgars on the western Pontic–Caspian steppe (modern southern Ukraine and southwest Russia). Great Bulgaria was originally centered between the Dniester and lower Volga.

The original capital was Phanagoria on the Taman Peninsula between the Black and Azov seas. In the mid-7th century, Great Bulgaria expanded west to include Avar territory and was centered on Poltava. During the late 7th century, however, an Avar-Slavic alliance in the west, and Khazars in the east, defeated the Bulgars, and Great Bulgaria disintegrated. Successor states are the First Bulgarian Empire and Volga Bulgaria.

The Slavs or Slavic people are a major ethnic group in Europe. They speak Slavic languages and preserve Slavic culture. There are 13 Slavic countries in Europe, which include: Poland, the Czech Republic, Slovakia, Russia, Belarus, Ukraine, Slovenia, Croatia, Bosnia and Herzegovina, Serbia, Montenegro, North Macedonia, and Bulgaria; the Slavs comprise a population of around 300 million people. There are three different Slavic ethnic groups: the West Slavs, the East Slavs, and the South Slavs; the Poles, Silesians, Kashubians, Sorbs, Czechs, and Slovaks are West Slavs; Russians, Belarusians, Ukrainians, and Rusyns are East Slavs; while Slovenes, Resians, Croats, Bosniaks, Serbs, Montenegrins, Torlakians, the Gorani, the Torbeši, Macedonians, and Bulgarians are South Slavs. Slavs are geographically distributed throughout the northern parts of Eurasia; they predominantly inhabit Central Europe, Eastern Europe, Southeastern Europe, and Northern Asia, though there is a large Slavic minority scattered across the Baltic states and Central Asia, and a substantial Slavic diaspora in the Americas, Western Europe, and Northern Europe.

Early Slavs lived during the Migration Period and the Early Middle Ages (approximately from the 5th to the 10th century AD), and came to control large parts of Central, Eastern, and Southeast Europe between the sixth and seventh centuries. Beginning in the 7th century, they were gradually Christianized. By the 12th century, they formed the core population of a number of medieval Christian states: East Slavs in the Kievan Rus', South Slavs in the Bulgarian Empire, the Principality of Serbia, the Duchy of Croatia and the Banate of Bosnia, and West Slavs in the Principality of Nitra, Great Moravia, the Duchy of Bohemia, and the Kingdom of Poland.

The Cyrillic script (/sɪˈrɪlɪk/ sih-RI-lik) is a writing system used for various languages across Eurasia. It is the designated national script in various Slavic, Turkic, Mongolic, Uralic, Caucasian and Iranic-speaking countries in Southeastern Europe, Eastern Europe, the Caucasus, Central Asia, North Asia, and East Asia, and used by many other minority languages.

As of 2019, around 250 million people in Eurasia use Cyrillic as the official script for their national languages, with Russia accounting for about half of them. With the accession of Bulgaria to the European Union in 2007, Cyrillic became the third official script of the European Union, following the Latin and Greek alphabets.

Georgia is a country in the Caucasus region on the coast of the Black Sea. It is located at the intersection of Eastern Europe and West Asia, and is today generally regarded as part of Europe. It is bordered to the north and northeast by Russia, to the south by Turkey and Armenia, and to the southeast by Azerbaijan. Georgia covers an area of 69,700 square kilometres (26,900 sq mi). It has a population of 3.9 million, of which over a third live in the capital and largest city, Tbilisi. Ethnic Georgians, who are native to the region, constitute a majority of the country's population and are its titular nation.

Georgia has been inhabited since prehistory, hosting the world's earliest known sites of winemaking, gold mining, and textiles. The classical era saw the emergence of several kingdoms, such as Colchis and Iberia, that formed the nucleus of the modern Georgian state. In the early fourth century, Georgians officially adopted Christianity, which contributed to their unification under the Kingdom of Georgia. Georgia reached its Golden Age during the High Middle Ages under the reigns of King David IV and Queen Tamar. Beginning in the 15th century, the kingdom declined and disintegrated due to internal discord and pressure from various regional powers, including the Mongols, the Ottoman Empire, and Persia, before being gradually annexed into the Russian Empire starting in 1801.

A spit or sandspit is a deposition bar or beach landform off coasts or lake shores. It develops in places where re-entrance occurs, such as at a cove's headlands, by the process of longshore drift by longshore currents. The drift occurs because waves meet the beach at an oblique angle, moving sediment down the beach in a zigzag pattern. This is complemented by longshore currents, which further transport sediment through the water alongside the beach. These currents are caused by the same waves that cause the drift.

Ukraine is a country in Eastern Europe. It is the second-largest country in Europe after Russia, which borders it to the east and northeast. Ukraine also borders Belarus to the north; Poland and Slovakia to the west; Hungary, Romania and Moldova to the southwest; and the Black Sea and the Sea of Azov to the south and southeast. Kyiv is the nation's capital and largest city, followed by Kharkiv, Odesa, and Dnipro. Ukraine's official language is Ukrainian.

Humans have inhabited Ukraine since 32,000 BC. During the Middle Ages, it was the site of early Slavic expansion and later became a key centre of East Slavic culture under the state of Kievan Rus', which emerged in the 9th century. Kievan Rus' became the largest and most powerful realm in Europe in the 10th and 11th centuries, but gradually disintegrated into rival regional powers before being destroyed by the Mongols in the 13th century. For the next 600 years the area was contested, divided, and ruled by a variety of external powers, including the Grand Duchy of Lithuania, the Kingdom of Poland, the Polish–Lithuanian Commonwealth, the Austrian Empire, the Ottoman Empire, and the Tsardom of Russia.

Sevastopol (/ˌsɛvəˈstoʊpəl, sɪˈvæstəpoʊl/ SEV-ə-STOH-pəl, siv-AST-ə-pohl), sometimes written Sebastopol, is the largest city in Crimea and a major port on the Black Sea. Due to its strategic location and the navigability of the city's harbours, Sevastopol has been an important port and naval base throughout its history. Since the city's founding in 1783, it has been a major base for Russia's Black Sea Fleet. During the Cold War of the 20th century, it was a closed city. The total administrative area is 864 square kilometres (334 sq mi) and includes a significant amount of rural land. The urban population, largely concentrated around Sevastopol Bay, is 479,394, and the total population is 547,820.

Sevastopol, along with the rest of Crimea, is internationally recognised as part of Ukraine, and under the Ukrainian legal framework, it is administratively one of two cities with special status (the other being Kyiv). However, it has been occupied by Russia since 27 February 2014, before Russia annexed Crimea on 18 March 2014 and gave it the status of a federal city of Russia. Both Ukraine and Russia consider the city administratively separate from the Autonomous Republic of Crimea and the Republic of Crimea, respectively. The city's population has an ethnic Russian majority and a substantial minority of Ukrainians and Crimean Tatars.

Novorossiysk (Russian: Новоросси́йск, IPA: [nəvərɐˈsʲijsk] ; Adyghe: ЦӀэмэз, romanized: C̣ămăz) is a city in Krasnodar Krai, Russia. It is one of the largest ports on the Black Sea. It was one of the few cities designated by the Soviet Union as a Hero City. The population was 262,293 (2021 census); 241,952 (2010 census); 232,079 (2002 census); 185,938 (1989 Soviet census).

Simferopol (/ˌsɪmfəˈroʊpəl/ SIM-fər-OH-pəl), also known as Aqmescit, is the second-largest city on the Crimean Peninsula. The city, along with the rest of Crimea, is internationally recognized as part of Ukraine, but controlled by Russia. It is considered the capital of the Autonomous Republic of Crimea.

Since 2014 it has been under the de facto control of Russia, which annexed Crimea that year and regards Simferopol as the capital of the Republic of Crimea.

Eastern Orthodoxy, otherwise known as Eastern Orthodox Christianity or Byzantine Christianity, is one of the three main branches of Chalcedonian Christianity, alongside Catholicism and Protestantism. Like the Pentarchy of the first millennium, the mainstream (or "canonical") Eastern Orthodox Church is organised into autocephalous churches independent from each other. In the 21st century, the number of mainstream autocephalous churches is seventeen; there also exist autocephalous churches unrecognized by those mainstream ones. Autocephalous churches choose their own primate. Autocephalous churches can have jurisdiction (authority) over other churches, some of which have the status of "autonomous" which means they have more autonomy than simple eparchies.

Many of these jurisdictions correspond to the territories of one or more modern states; the Patriarchate of Moscow, for example, corresponds to Russia and some of the other post-Soviet states. They can also include metropolises, bishoprics, parishes, monasteries, or outlying metochia corresponding to diasporas that can also be located outside the country where the primate resides (e.g., the case of the Ecumenical Patriarchate of Constantinople whose canonical territory is located partly in northern Greece and the east); sometimes they overlap (the case of Moldova where the jurisdictions of the patriarchs of Bucharest and of Moscow overlap).

Eastern Europe is a subregion of the European continent. As a largely ambiguous term, it has a wide range of geopolitical, geographical, ethnic, cultural and socio-economic connotations. Its eastern boundary is marked by the Ural Mountains, and its western boundary is defined in various ways. Narrow definitions, in which Central and Southeast Europe are counted as separate regions, include Belarus, Russia and Ukraine. In contrast, broader definitions include Moldova and Romania, but also some or all of the Balkans, the Baltic states, the Caucasus, and the Visegrád group. In Eastern Europe, Russia is the largest and most populous country.

The region represents a significant part of European culture; the main socio-cultural characteristics of Eastern Europe have historically largely been defined by the traditions of the Slavs, as well as by the influence of Eastern Christianity as it developed through the Eastern Roman Empire and the Ottoman Empire. Another definition was created by the Cold War, as Europe was ideologically divided by the Iron Curtain, with "Eastern Europe" being synonymous with communist states constituting the Eastern Bloc under the influence of the Soviet Union.
