Federal subjects of Russia in the context of "Federal cities of Russia"

Russian Classification on Objects of Administrative Division (Russian: Общеросси́йский классифика́тор объе́ктов администрати́вно-территориа́льного деле́ния), or OKATO (Russian: ОКАТО), also called All-Russian classification on units of administrative and territorial distribution in English, is one of several Russian national registers. OKATO's purpose is organization of information about structure of the administrative divisions of the federal subjects of Russia.

The document assigns numeric codes to each administrative division of the country, which are hierarchically structured from the federal subject level down to selsoviet level; an expanded version also includes listings of individual inhabited localities within each administrative division.

Krasnodar Krai (Russian: Краснода́рский край, romanized: Krasnodarskiy kray, [krəsnɐˈdarskʲɪj kraj]) is a federal subject of Russia (a krai), located in the North Caucasus region in Southern Russia and is administratively a part of the Southern Federal District. Its administrative center is the city of Krasnodar. The third most populous federal subject in Russia, it had a population of 5,838,273 as of the 2021 Census.

Krasnodar Krai is formally and informally referred to as Kuban (Russian: Кубань), a term denoting the historical region of Kuban situated between the Sea of Azov and the Kuban River which is predominantly within the krai. It is bordered by Rostov Oblast to the north, Stavropol Krai to the east, Karachay-Cherkessia to the south-east. Adygea is an enclave entirely within the krai. Krasnodar Krai shares an international border with Georgia and borders annexed Crimea to the west, across the Kerch Strait.

Siberia (/saɪˈbɪəriə/ sy-BEER-ee-ə; Russian: Сибирь, romanized: Sibir', IPA: [sʲɪˈbʲirʲ] ), also known as Asian Russia, is an extensive geographical region comprising all of North Asia, from the Ural Mountains in the west to the Pacific Ocean in the east. It has formed a part of the sovereign territory of Russia and its predecessor states since the lengthy conquest of Siberia, which began with the fall of the Khanate of Sibir in 1582 and concluded with the annexation of Chukotka in 1778. Siberia is vast and sparsely populated, covering an area of over 13.1 million square kilometres (5,100,000 sq mi) – about three-quarters of Russia's total area, but home to roughly a quarter of Russia's population. Novosibirsk, Krasnoyarsk, and Omsk are the largest cities in the area.

Because Siberia is a geographic and historic concept and not a political entity, there is no single precise definition of its territorial borders. Traditionally, Siberia spans the entire expanse of land from the Ural Mountains to the Pacific Ocean, with the Ural River usually forming the southernmost portion of its western boundary, and includes most of the drainage basin of the Arctic Ocean. It is further defined as stretching from the territories within the Arctic Circle in the north to the northern borders of Kazakhstan, Mongolia, and China in the south, although the hills of north-central Kazakhstan are also commonly included. The Russian government divides the region into three federal districts (groupings of Russian federal subjects), of which only the central one is officially referred to as "Siberian"; the other two are the Ural and Far Eastern federal districts, named for the Ural and Russian Far East regions that correspond respectively to the western and eastern thirds of Siberia in the broader sense.

Magnitogorsk (Russian: Магнитого́рск, IPA: [məɡnʲɪtɐˈɡorsk], lit. '[city] of the magnetic mountain') is an industrial city in Chelyabinsk Oblast, Russia, on the eastern side of the extreme southern extent of the Ural Mountains by the Ural River. Its population is currently 410,594 (2021 census).

Magnitogorsk was named after Mount Magnitnaya, a geological anomaly that once consisted almost completely of iron ore, around 55% to 60% iron. It is the second-largest city in Russia that is not the administrative centre of any federal subject or district, after Tolyatti. Magnitogorsk contains the largest iron and steel works in the country: Magnitogorsk Iron and Steel Works. The official motto of the city is "the place where Europe and Asia meet", as the city straddles von Strahlenberg's line.

Lake Baikal is a rift lake and the deepest lake in the world. It is situated in southern Siberia, Russia between the federal subjects of Irkutsk Oblast to the northwest and the Republic of Buryatia to the southeast.

At 31,722 km (12,248 sq mi)—slightly larger than Belgium—Lake Baikal is the world's seventh-largest lake by surface area, as well as the second largest lake in Eurasia after the Caspian Sea. However, because it is also the deepest lake, with a maximum depth of 1,642 metres (5,387 feet), Lake Baikal is the world's largest freshwater lake by volume, containing 23,615.39 km (5,670 cu mi) of water or 22–23% of the world's fresh surface water, more than all of the North American Great Lakes combined. It is also the world's oldest lake at 25–30 million years, and among the clearest. It is estimated that the lake contains around 19% of the unfrozen fresh water on the planet.

The Aleutian Islands (/əˈluːʃən/ ə-LOO-shən; Russian: Алеутские острова, romanized: Aleutskiye ostrova; Aleut: Unangam Tanangin, "land of the Aleuts"; possibly from the Chukchi aliat, or "island")—also called the Aleut Islands, Aleutic Islands, or, before 1867, the Catherine Archipelago—are a chain of 14 main, larger volcanic islands and 55 smaller ones.

Most of the islands belong to the U.S. state of Alaska, with the archipelago encompassing the Aleutians West Census Area and the Aleutians East Borough. The Commander Islands, located further to the west, belong to the Russian federal subject of Kamchatka Krai, of the Russian Far East.

The Buryats are a Mongolic ethnic group native to southeastern Siberia who speak the Buryat language. They are one of the two largest indigenous groups in Siberia, the other being the Yakuts. The majority of the Buryats today live in their titular homeland, the Republic of Buryatia, a federal subject of Russia which sprawls along the southern border and partially straddles Lake Baikal. Smaller groups of Buryats also inhabit Ust-Orda Buryat Okrug (Irkutsk Oblast) and the Agin-Buryat Okrug (Zabaykalsky Krai) which are to the west and east of Buryatia respectively as well as northeastern Mongolia and Inner Mongolia, China. Traditionally, they formed the major northern subgroup of the Mongols.

Buryats share many customs with other Mongolic peoples, including nomadic herding, and erecting gers for shelter. Today the majority of Buryats live in and around Ulan-Ude, the capital of the Buryat Republic, although many still follow a more traditional lifestyle in the countryside. They speak a central Mongolic language called Buryat. UNESCO's 2010 edition of the Atlas of the World's Languages in Danger classifies the Buryat language as "severely endangered".

The republics are one type of federal subject of the Russian Federation. Twenty-one republics are internationally recognized as part of Russia; another is under its de facto control. The original republics were created as nation states for ethnic minorities. The indigenous ethnicity that gives its name to the republic is called the titular nationality. However, due to centuries of Russian migration, a titular nationality may not be a majority of its republic's population. By 2017, the autonomous status of all republics was formally abolished, making the republics politically equivalent to the other federal subjects of Russia.

Formed in the early 20th century by Vladimir Lenin and the Bolsheviks after the collapse of the Russian Empire in 1917, republics were intended to be nominally independent regions of Soviet Russia with the right to self-determination. Lenin's conciliatory stance towards Russia's minorities made them allies in the Russian Civil War and with the creation of the Soviet Union in 1922 the regions became autonomous republics, albeit subordinate to a union republic. While officially autonomous, the autonomies of these administrative units varied throughout the history of the Soviet Union but largely remained under the control of the central government. The 1980s saw an increase in the demand of autonomy as the Soviet Union began large scale reforms of its centralized system. In 1990, most of the autonomous republics declared their sovereignty. The Soviet Union collapsed in 1991 and Russia became independent. The current republics were established with the signing of the Federation Treaty in 1992, which gave them substantial rights and autonomy.

A krai or kray is one of the types of federal subjects of modern Russia, and was a type of geographical administrative division in the Russian Empire and the Russian SFSR.

Etymologically, the word is related to the verb кроить (kroítǐ [krɐˈitʲ]), meaning 'to cut'. Historically, krais were vast territories located along the periphery of the Russian state, since the word krai also means 'border' or 'edge', i.e., 'a place of the cut-off'. In English the term is often translated as 'territory'. As of 2015, the administrative usage of the term is mostly traditional, as some oblasts also fit this description and there is no difference in constitutional legal status in Russia between the krais and the oblasts.
