Federal cities of Russia in the context of "Saint Petersburg"

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.

On 27 February 2014, unmarked Russian soldiers were deployed to the Crimean Peninsula in order to wrest control of it from Ukraine, starting the Russo-Ukrainian War. This military occupation, which the Ukrainian government considers to have begun on 20 February laid the foundation for the Russian annexation of Crimea on 18 March 2014. Under Russia, the Ukrainian Autonomous Republic of Crimea was replaced by the Republic of Crimea, though the legitimacy of the latter is scarcely recognized internationally.

The occupation began during Ukraine's Revolution of Dignity, which ousted pro-Russian president Viktor Yanukovych. Russian special forces without insignia took control of Crimea's government buildings, surrounded Ukrainian military bases, and blockaded the peninsula. A pro-Russian government was installed and a referendum on Crimea's status was held under occupation. According to the Russian-installed authorities, the result was in favour of joining Russia. It annexed Crimea on 18 March 2014, re-organizing it as a Russian republic and turning Sevastopol into a Russian federal city.

This is a list of cities and towns in Russia and parts of the Russian-occupied territories of Ukraine with a population of over 50,000 as of the 2021 Census. The figures are for the population within the limits of the city/town proper, not the urban area or metropolitan area.

The list includes Sevastopol and settlements within the Republic of Crimea which are internationally recognized as part of Ukraine and were not subject to the 2010 census. Additionally, settlements within the Donetsk People's Republic, Kherson Oblast, Luhansk People's Republic, and Zaporozhye Oblast, are internationally recognized as part of Ukraine and were not subject to the 2010 census. Only settlements presently controlled by Russia are included; settlements under the control of Ukraine are not included. The city of Zelenograd (a part of the federal city of Moscow) and the municipal cities/towns of the federal city of St. Petersburg are also excluded, as they are not enumerated in the 2021 census as stand-alone localities. The sixteen largest cities (cities with over 1,000,000 inhabitants) have a total population of 35,509,177, or roughly 24.1% of the country's total population.

In February and March 2014, Russia invaded the Crimean Peninsula, part of Ukraine, and then annexed it. This took place in the relative power vacuum immediately following the Revolution of Dignity. It marked the beginning of the Russo-Ukrainian War.

The events in Kyiv that ousted Ukrainian president Viktor Yanukovych on 22 February 2014 sparked both pro-Russian and anti-separatism demonstrations in Crimea. At the same time, Russian president Vladimir Putin told his security chiefs to begin work on "returning Crimea to Russia". On 27 February, Russian special forces without insignia seized strategic sites across Crimea. Russia at first denied involvement, but Putin later admitted that they were Russian troops. As the armed men occupied Crimea's parliament, it dismissed the Crimean government, installed the pro-Russian Aksyonov government, and announced a referendum on Crimea's status. The referendum was held under Russian occupation and, according to the Russian-installed authorities, the result was overwhelmingly in favor of joining Russia. The next day, 17 March 2014, Crimea's authorities declared independence and requested to join Russia. Russia formally incorporated Crimea on 18 March 2014 as the Republic of Crimea and federal city of Sevastopol. Following the annexation, Russia militarized the peninsula and warned against any outside intervention.

The federal subjects of Russia, also referred to as the subjects of the Russian Federation (Russian: субъекты Российской Федерации, romanized: subyekty Rossiyskoy Federatsii) or simply as the subjects of the federation (Russian: субъекты федерации, romanized: subyekty federatsii), are the constituent entities of Russia, its top-level political divisions. According to the Constitution of Russia, the federation consists of republics, krais, oblasts, cities of federal importance, an autonomous oblast, and autonomous okrugs, all of which are equal subjects of the federation.

Every federal subject has its own head, a parliament, and a constitutional court. Each subject has its own constitution or charter and legislation, although the authority of these organs differ. Subjects have equal rights in relations with federal government bodies. The subjects have equal representation – two delegates each – in the Federation Council, the upper house of the Federal Assembly. They differ in the degree of autonomy they enjoy; republics are offered more autonomy.
