List of metropolitan areas in Europe in the context of "Paris"

Russia, or the Russian Federation, is a country in Eastern Europe and North Asia. It is the largest country in the world, spanning eleven time zones and sharing land borders with fourteen countries. With a population of over 140 million, Russia is the most populous country in Europe and the ninth-most populous country in the world. It is a highly urbanised country, with sixteen of its urban areas having more than 1 million inhabitants. Moscow, the most populous metropolitan area in Europe, is the capital and largest city of Russia; and Saint Petersburg is its second-largest city and cultural centre.

Human settlement on the territory of modern Russia dates back to the Lower Paleolithic. The East Slavs emerged as a recognised group in Europe between the 3rd and 8th centuries AD. The first East Slavic state, Kievan Rus', arose in the 9th century, and in 988, it adopted Orthodox Christianity from the Byzantine Empire. Kievan Rus' ultimately disintegrated; the Grand Duchy of Moscow led the unification of Russian lands, leading to the proclamation of the Tsardom of Russia in 1547. By the early 18th century, Russia had vastly expanded through conquest, annexation, and the efforts of Russian explorers, developing into the Russian Empire, which remains the third-largest empire in history. However, with the Russian Revolution in 1917, Russia's monarchic rule was abolished and eventually replaced by the Russian SFSR—the world's first constitutionally socialist state. Following the Russian Civil War, the Russian SFSR established the Soviet Union with three other Soviet republics, within which it was the largest and principal constituent. The Soviet Union underwent rapid industrialisation in the 1930s, amidst the deaths of millions under Joseph Stalin's rule, and later played a decisive role for the Allies in World War II by leading large-scale efforts on the Eastern Front—rising as a global superpower. With the onset of the Cold War, it competed with the United States for ideological dominance and international influence. The Soviet era of the 20th century saw some of the most significant Russian technological achievements, including the first human-made satellite and the first human expedition into outer space.

This list ranks European cities by population within city limits. The largest cities in Europe have official populations of over one million inhabitants within their city boundaries. These rankings are based on populations contained within city administrative boundaries, as opposed to urban areas or metropolitan areas, which necessarily have larger populations than the cities at their core.

The limits of a city proper can differ greatly from the size of the city's urban area, so the figures in this list may not give an accurate view of the comparative population of different urban areas and should be treated with caution. For example, the Paris metropolitan area is the fourth most populous in Europe, but the strict definition of the administrative limits of the City of Paris results in a far lower population.

Throughout most of its history, Istanbul has ranked among the largest cities in the world. By 500 CE, Constantinople had somewhere between 400,000 and 500,000 people, edging out its predecessor, Rome, for world's largest city. Constantinople jostled with other major historical cities, such as Baghdad, Chang'an, Kaifeng and Merv for the position of world's most populous city until the 12th century. It never returned to being the world's largest, but remained Europe's largest city from 1500 to 1750, when it was surpassed by London.

The Turkish Statistical Institute estimates that the population of Istanbul Metropolitan Municipality was 15,701,602 at the end of 2024, hosting 18 percent of the country's population. Then about 97–98% of the inhabitants of the metropolitan municipality were within city limits, up from 89% in 2007 and 61% in 1980. 64.9% of the residents live on the European side and 35.1% on the Asian side. While the city ranks as the world's 5th-largest city proper, it drops to the 24th place as an urban area and to the 18th place as a metro area because the city limits are roughly equivalent to the agglomeration. Today, it forms one of the largest urban agglomerations in Europe, alongside Moscow. The city's annual population growth of 3.45 percent ranks as the highest among the seventy-eight largest metropolises in the Organisation for Economic Co-operation and Development. The high population growth mirrors an urbanization trend across the country, as the second and third fastest-growing OECD metropolises are the Turkish cities of İzmir and Ankara.

Moscow is the capital and largest city of Russia, standing on the Moskva River in Central Russia. It has a population estimated at over 13 million residents within the city limits, over 19.1 million residents in the urban area, and over 21.5 million residents in its metropolitan area. The city covers an area of 2,511 square kilometers (970 sq mi), while the urban area covers 5,891 square kilometers (2,275 sq mi), and the metropolitan area covers over 26,000 square kilometers (10,000 sq mi). Moscow is among the world's largest cities, being the most populous city entirely in Europe, the largest urban and metropolitan area in Europe, and the largest city by land area on the European continent.

First documented in 1147, Moscow became the capital of the Grand Principality of Moscow, which led the unification of the Russian lands in the 15th century and became the center of a unified state. Following the proclamation of the Tsardom of Russia in 1547, Moscow remained the political and economic center for most of its history. During the reign of Peter the Great, the Russian capital was moved to the newly founded city of Saint Petersburg in 1712, leading to a decline in Moscow's importance throughout the imperial period. Following the Russian Revolution and the establishment of the Russian SFSR, the capital was moved back to Moscow in 1918. The city later became the political center of the Soviet Union and experienced significant population growth throughout the Soviet period. In the aftermath of the dissolution of the Soviet Union, Moscow remained the capital city of the newly reconstituted Russian Federation and has experienced continued growth.

Catalonia is an autonomous community of Spain, designated as a nationality by its Statute of Autonomy. Most of its territory (except the Val d'Aran) is situated on the northeast of the Iberian Peninsula, to the south of the Pyrenees mountain range. Catalonia is administratively divided into four provinces or eight vegueries (regions), which are in turn divided into 43 comarques. The capital and largest city, Barcelona, is the second-most populous municipality in Spain and the fifth-most populous urban area in the European Union.

Modern-day Catalonia comprises most of the medieval and early modern Principality of Catalonia, with the remainder of the northern area now part of France's Pyrénées-Orientales. It is bordered by France (Occitanie) and Andorra to the north, the Mediterranean Sea to the east, and the Spanish autonomous communities of Aragon to the west and Valencia to the south. In addition to its approximately 580 km of coastline, Catalonia also has major high landforms such as the Pyrenees and the Pre-Pyrenees, the Transversal Range (Serralada Transversal) or the Central Depression. The official languages are Catalan, Spanish, and the Aranese dialect of Occitan.

Katowice (/ˌkɑtəˈvitsə/, Polish: [katɔˈvit͡sɛ] , Silesian: Katowice, German: Kattowitz) is the capital city of the Silesian Voivodeship in southern Poland and the central city of the Katowice urban area. As of 2021, Katowice has an official population of 286,960, and a resident population estimate of around 315,000. Katowice is a central part of the Metropolis GZM, with a population of 2.3 million, and a part of a larger Katowice–Ostrava metropolitan area that extends into the Czech Republic and has a population of around 5 million people, making it one of the most populous metropolitan areas in the European Union.

Katowice was founded as a village in the 16th century, whereas several modern districts of Katowice were founded as villages in the Middle Ages. Throughout the mid-18th century, Katowice grew following the discovery of rich coal reserves in the area. In the first half of the 19th century, intensive industrialization transformed local mills and farms into industrial steelworks, mines, foundries and artisan workshops. The city has since reshaped its economy from a heavy industry-based one to professional services, education and healthcare. The entire metropolitan area is the 16th most economically powerful city by GDP in the European Union with an output amounting to $114.5 billion. Katowice Special Economic Zone is ranked fourth on the list of the TOP10 Global Free Zones.
