The Republics of the Union of Soviet Socialist Republics or the Union Republics were national-based administrative units of the Union of Soviet Socialist Republics (USSR). The Soviet Union was formed in 1922 by a treaty between the Soviet republics of Byelorussia, Russia, Transcaucasia, and Ukraine, by which they became its constituent republics.

The Russian Soviet Federative Socialist Republic, Russian SFSR or RSFSR, previously known as the Russian Soviet Republic and the Russian Socialist Federative Soviet Republic as well as being unofficially known as Soviet Russia, the Russian Federation or simply Russia, was an independent federal socialist state from 1917 to 1922, and afterwards the largest and most populous of the Soviet socialist republics of the Soviet Union (USSR) from 1922 to 1991, until becoming a sovereign part of the Soviet Union with priority of Russian laws over Union-level legislation in 1990 and 1991, the last two years of the existence of the USSR. The Russian Republic was composed of sixteen smaller constituent units of autonomous republics, five autonomous oblasts, ten autonomous okrugs, six krais and forty oblasts. Russians formed the largest ethnic group. The capital of the Russian SFSR was Moscow and the other major urban centers included Leningrad, Stalingrad, Novosibirsk, Sverdlovsk, Gorky and Kuybyshev. It was the first Marxist-Leninist state in the world.

The federal subjects of Russia, also referred to as the subjects of the Russian Federation or simply as the subjects of the federation, are the constituent entities of Russia, its top-level political divisions according to the Constitution of Russia. Kaliningrad Oblast is the only federal subject geographically separated from the rest of the Russian Federation by other countries.

Leningrad Oblast is a federal subject of Russia. It was established on 1 August 1927, although it was not until 1946 that the oblast's borders had been mostly settled in their present position. The oblast was named after the city of Leningrad. In 1991, the city restored its original name, Saint Petersburg, but the oblast retains the name of Leningrad. The capital and largest city is Gatchina.

A city is a human settlement of notable size. It can be defined as a permanent and densely settled place with administratively defined boundaries whose members work primarily on non-agricultural tasks. Cities generally have extensive systems for housing, transportation, sanitation, utilities, land use, production of goods, and communication. Their density facilitates interaction between people, government organisations and businesses, sometimes benefiting different parties in the process, such as improving efficiency of goods and service distribution.

Russian is an East Slavic language mainly spoken in Russia. It is the native language of the Russians and belongs to the Indo-European language family. It is one of four living East Slavic languages, and is also a part of the larger Balto-Slavic languages. Besides Russia itself, Russian is an official language in Belarus, Kazakhstan, and Kyrgyzstan, and is used widely as a lingua franca throughout Ukraine, the Caucasus, Central Asia, and to some extent in the Baltic states. It was the de facto language of the former Soviet Union, and continues to be used in public life with varying proficiency in all of the post-Soviet states.

A dacha is a seasonal or year-round second home, often located in the exurbs of post-Soviet countries, including Russia. A cottage or shack serving as a family's main or only home, or an outbuilding, is not considered a dacha, although some dachas recently have been converted to year-round residences and vice versa.

A resort is a self-contained commercial establishment that tries to provide most of a vacationer's wants, such as food, drink, swimming, lodging, sports, entertainment, and shopping, on the premises. The term resort may be used for a hotel property that provides an array of amenities, typically including entertainment and recreational activities. A hotel is frequently a central feature of a resort, such as the Grand Hotel at Mackinac Island, Michigan. Some resorts are also condominium complexes that are timeshares or owned fractionally or wholly owned condominium. A resort is not always a commercial establishment operated by a single company, but in the late 20th century, that sort of facility became more common.

Eastern Orthodox church architecture constitutes a distinct, recognizable family of styles among church architectures. These styles share a cluster of fundamental similarities, having been influenced by the common legacy of Byzantine architecture from the Eastern Roman Empire. Some of the styles have become associated with the particular traditions of one specific autocephalous Eastern Orthodox patriarchate, whereas others are more widely used within the Eastern Orthodox Church.
