Capital city in the context of Korosten

Athens is the capital and largest city of Greece. A significant coastal urban area in the Mediterranean, Athens is also the capital of the Attica region and is the southernmost capital on the European mainland. With its urban area's population numbering over 3.6 million, it is the eighth-largest urban area in the European Union (EU). The Municipality of Athens (also City of Athens), which constitutes a small administrative unit of the entire urban area, had a population of 643,452 in 2021, within its official limits, and a land area of 38.96 km (15.04 sq mi).

Athens is one of the world's oldest cities, with its recorded history spanning over 3,400 years, and its earliest human presence beginning somewhere between the 11th and 7th millennia BCE. According to Greek mythology the city was named after Athena, the ancient Greek goddess of wisdom, but modern scholars generally agree that the goddess took her name after the city. Classical Athens was one of the most powerful city-states in ancient Greece. It was a centre for democracy, the arts, education and philosophy, and was highly influential throughout the European continent, particularly in Ancient Rome. For this reason it is often regarded as the cradle of Western civilisation and the birthplace of democracy in its own right independently from the rest of Greece.

Attica (/ˈætɪkə/ AT-ih-kə; Greek: Περιφέρεια Αττικής, romanized: Periféria Attikís, [periˈferi.a atiˈcis]) is an administrative region of Greece that encompasses the entire Athens metropolitan area, the core city of which is the country's capital and largest city, Athens. The region is coextensive with the former Attica Prefecture of Central Greece and covers a greater area than the historical region of Attica.

A province is an administrative division within a country or state. The term derives from the ancient Roman provincia, which was the major territorial and administrative unit of the Roman Empire's territorial possessions outside Italy. The term province has since been adopted by many countries. In some countries with no actual provinces, "the provinces" is a metaphorical term meaning "outside the capital city".

While some provinces were produced artificially by colonial powers, others were formed around local groups with their own ethnic identities. Many have their own powers independent of central or federal authority, especially in Canada and Pakistan. In other countries, like China or France, provinces are the creation of central government, with very little autonomy.

A seat of government is a "building, complex of buildings or the city from which a government exercises its authority". When referring to a city, the seat of government is generally the capital of the state or administrative entity in question, although there are exceptions. Particular terms for the seat of certain territorial subdivisions are administrative centre, county seat (common in the United States), county town (United Kingdom and Ireland), or barrio-pueblo (Puerto Rico), among others; buildings that may function as seats of government include official residences, supreme court buildings, city or town halls, administrative or executive buildings, shire or county halls, legislative buildings, and barangay halls.

Some countries can be considered to have multiple capitals. In some cases, one city is the capital for some purposes, and one or more others are capital for other purposes, without any being considered an official capital in preference to the others. There are also cases where there is a single legally defined capital, but one or more other cities operate as the seat of government of some or all parts of the national government; in these situations, sources may disagree on whether these other cities are considered additional capital cities.

Thessaloniki (/ˌθɛsələˈniːki/; Greek: Θεσσαλονίκη [θesaloˈnici] ; also known by various spellings and names) is a city in northern Greece. The nation's second-largest, with slightly over one million inhabitants in its metropolitan area, it is the capital of the geographic region of Macedonia, the administrative region of Central Macedonia and the Decentralized Administration of Macedonia and Thrace. It is also known in Greek as i Symprotévousa, literally "the co-capital", a reference to its historical status as the "co-reigning" city (Symvasilévousa) of the Byzantine Empire alongside Constantinople.

Thessaloniki is located on the Thermaic Gulf, at the northwest corner of the Aegean Sea. It is bounded on the west by the delta of the Axios. The municipality of Thessaloniki, the historical centre, had a population of 319,045 in 2021, while the Thessaloniki metropolitan area had 1,006,112 inhabitants and the greater region had 1,092,919. It is Greece's second major economic, industrial, commercial and political centre, and a major transportation hub for Greece and southeastern Europe, notably through the Port of Thessaloniki. The city is renowned for its festivals, events and vibrant cultural life in general. Events such as the Thessaloniki International Fair and the Thessaloniki International Film Festival are held annually. Thessaloniki was the 2014 European Youth Capital. The city's main university, Aristotle University, is the largest in Greece and the Balkans.

Heraklion, Herakleion (/hɪˈrækliən/ hih-RAK-lee-ən; Greek: Ηράκλειο, Iráklio, pronounced [iˈrakli.o], not to be mistaken with Heracleion, Egypt) or Iraklion, is the largest city and the administrative capital of the island of Crete and capital of Heraklion regional unit. It is the fourth largest city in Greece, and the largest city in the Greek islands, with a municipal population of 179,302 (2021) and 211,370 in its wider metropolitan area, according to the 2011 census.The greater area of Heraklion has been continuously inhabited since at least 7000 BCE, making it one of the oldest inhabited regions in Europe. It is also home to the ancient Knossos Palace, a major center of the Minoan civilization dating back to approximately 2000-1350 BCE, often considered Europe's oldest city. The palace is one of the most significant archaeological sites in Greece, second only to the Parthenon in terms of visitor numbers.

Heraklion was Europe's fastest growing tourism destination for 2017, according to Euromonitor, with an 11.2% growth in international arrivals. According to the ranking, Heraklion was ranked as the 20th most visited region in Europe, as the 66th area on the planet and as the 2nd in Greece for the year 2017, with 3.2 million visitors and the 19th in Europe for 2018, with 3.4 million visitors.

A city-state is an independent sovereign city which serves as the center of political, economic, and cultural life over its contiguous territory, as opposed to a regular state or country comprising a capital city and other cities and/or a countryside. City-states have existed in many parts of the world throughout history, including cities such as Rome, Carthage, Athens and Sparta and the Italian city-states during the Middle Ages and Renaissance, such as Florence, Venice, Genoa and Milan.

With the rise of nation states worldwide, there remains some disagreement on the number of modern city-states that still exist; Singapore, Monaco and Vatican City are the candidates most commonly discussed. Out of these, Singapore is the largest and most populous city-state in the world, with full sovereignty, international borders, its own currency, a robust military, and substantial international influence in its own right. The Economist refers to it as the "world's only fully functioning city-state".

Attica (Greek: Αττική, romanised: Attikí, Greek pronunciation: [atiˈci]; Ancient Greek: Ἀττική, romanised: Attikḗ, Ancient Greek pronunciation: [atːikɛ̌ː]), or the Attic Peninsula, is a historical region that encompasses the entire Athens metropolitan area, which consists of the city of Athens, the capital of Greece and the core city of the metropolitan area, as well as its surrounding suburban cities and towns. It is a peninsula projecting into the Aegean Sea, bordering on Boeotia to the north and Megaris to the west. The mines of Laurion were an important mining region located at Lavrio, on the southern tip of the peninsula.

The history of Attica is closely linked with that of Athens. In ancient times, Attica corresponded with the classical Athens city‑state. It was the most prominent region in Ancient Greece, specifically during the Golden Age of Athens in the classical period. Ancient Attica was divided into demoi, or municipalities, from the reform of Cleisthenes in 508/7 BC, grouped into three zones: urban (astu) in the region of Athens main town, and Piraeus (the port), coastal (paralia) along the coastline, and inland (mesogeia) in the interior.

Rome is the capital city and most populated comune (municipality) of Italy. It is also the administrative centre of the Lazio region and of the Metropolitan City of Rome. A special comune named Roma Capitale with 2,746,984 residents in 1,287.36 km (497.1 sq mi), Rome is the third most populous city in the European Union by population within city limits. The Metropolitan City of Rome Capital, with a population of 4,223,885 residents, is the most populous metropolitan city in Italy. Its metropolitan area is the third-most populous within Italy. Rome is located in the central-western portion of the Italian Peninsula, within Lazio (Latium), along the shores of the Tiber Valley. Vatican City (the smallest country in the world and headquarters of the worldwide Catholic Church under the governance of the Holy See) is an independent country inside the city boundaries of Rome, the only existing example of a country within a city. Rome is often referred to as the City of Seven Hills due to its geography, and also as the "Eternal City". Rome is generally considered to be one of the cradles of Western civilization and Western Christian culture, and the centre of the Catholic Church.

Rome's history spans 28 centuries. While Roman mythology dates the founding of Rome at around 753 BC, the site has been inhabited for much longer, making it a major human settlement for over three millennia and one of the oldest continuously occupied cities in Europe. The city's early population originated from a mix of Latins, Etruscans, and Sabines. Eventually, the city successively became the capital of the Roman Kingdom, the Roman Republic and the Roman Empire, and is regarded by many as the first-ever Imperial city and metropolis. It was first called The Eternal City (Latin: Urbs Aeterna; Italian: La Città Eterna) by the Roman poet Tibullus in the 1st century BC, and the expression was also taken up by Ovid, Virgil, and Livy. Rome is also called Caput Mundi (Capital of the World).

The Sahrawi Arab Democratic Republic (SADR), also known as the Sahrawi Republic and Western Sahara, is a partially recognized state in the western Maghreb, which claims the non-self-governing territory of Western Sahara, but controls only the easternmost one-fifth of that territory. It is recognized by 44 UN member states and South Ossetia. Between 1884 and 1975, Western Sahara was known as Spanish Sahara, a Spanish colony (later an overseas province). The SADR is one of the two African states in which Spanish is a significant language, the other being Equatorial Guinea.

The SADR was proclaimed by the Polisario Front on 27 February 1976, in Bir Lehlou, Western Sahara. The SADR government calls the territories under its control the Liberated Territories or the Free Zone. Morocco occupies the rest of the disputed territory, and calls these lands its Southern Provinces. The claimed capital city of the SADR is Laayoune (the largest city of the Western Sahara territory). Since the SADR does not control Laayoune, it has established a temporary capital in Tifariti, although most of the day-to-day administration happens in Rabuni, one of the Sahrawi refugee camps located in Tindouf, Algeria.

Puerto Rico (abbreviated PR), officially the Commonwealth of Puerto Rico, is a self-governing Caribbean archipelago and island organized as an unincorporated territory of the United States under the designation of commonwealth. Located about 1,000 miles (1,600 km) southeast of Miami, Florida, between the Dominican Republic in the Greater Antilles and the U.S. Virgin Islands in the Lesser Antilles, it consists of the eponymous main island and numerous smaller islands, including Vieques, Culebra, and Mona. With approximately 3.2 million residents, it is divided into 78 municipalities, of which the most populous is the capital municipality of San Juan, followed by those within the San Juan metropolitan area. Spanish and English are the official languages of the government, though Spanish predominates.

Puerto Rico was settled by a succession of Amerindian peoples beginning 2,000 to 4,000 years ago; these included the Ortoiroid, Saladoid, and Taíno. It was claimed by Spain following the arrival of Christopher Columbus in 1493 and subsequently colonized by Juan Ponce de León in 1508. Puerto Rico was contested by other European powers into the 18th century but remained a Spanish possession for the next 400 years. The decline of the Indigenous population, followed by an influx of Spanish settlers, primarily from the Canary Islands and Andalusia, and African slaves vastly changed the cultural and demographic landscape of the archipelago. Within the Spanish Empire, Puerto Rico played a secondary but strategically significant role compared to larger and wealthier colonies like Peru and New Spain. By the late 19th century, a distinct Puerto Rican identity began to emerge, centered on a fusion of European, African, and Indigenous elements. In 1898, following the Spanish–American War, Puerto Rico was acquired by the United States.

Seoul, officially Seoul Special Metropolitan City, is both the capital and largest city of South Korea, and the largest city in the whole of Korea. The broader Seoul Metropolitan Area, encompassing Seoul, Gyeonggi Province and Incheon, emerged as the world's sixth largest metropolitan economy in 2022, behind New York, Tokyo, Los Angeles, Paris, and London, and hosts more than half of South Korea's population. Although Seoul's population peaked at over 10 million, it has gradually decreased since 2014, standing at about 9.6 million residents as of 2024. Seoul is the seat of the South Korean government.

Seoul's history traces back to 18 BC when it was founded by the people of Baekje, one of the Three Kingdoms of Korea. During the Joseon dynasty, Seoul was officially designated as the capital, surrounded by the Fortress Wall of Seoul. In the early 20th century, Seoul was occupied by the Empire of Japan, temporarily renamed "Keijō" ("Gyeongseong" in Korean). The Korean War brought fierce battles, with Seoul changing hands four times and leaving the city mostly in ruins. Nevertheless, the city has since undergone significant reconstruction and rapid urbanization.

Sofia is the capital and largest city of Bulgaria. It is situated in the Sofia Valley at the foot of the Vitosha mountain, in the western part of the country. The city is built west of the Iskar river and has many mineral springs, such as the Sofia Central Mineral Baths. It has a humid continental climate.

Known as Serdica in antiquity, Sofia has been an area of human habitation since at least 7000 BC. The recorded history of the city begins with the attestation of the conquest of Serdica by the Roman Republic in 29 BC from the Celtic tribe Serdi. During the decline of the Roman Empire, the city was raided by Huns, Visigoths, Avars, and Slavs. In 809, Serdica was incorporated into the First Bulgarian Empire by Khan Krum and became known as Sredets. In 1018, the Byzantines ended Bulgarian rule until 1194, when it was reincorporated by the Second Bulgarian Empire. Sredets became a major administrative, economic, cultural and literary hub until its conquest by the Ottomans in 1382. From 1530 to 1836, Sofia was the regional capital of Rumelia Eyalet, the Ottoman Empire's largest and most important province. Bulgarian rule was restored in 1878. Sofia was selected as the capital of the Third Bulgarian State in the next year, ushering a period of intense demographic and economic growth.

Ankara is the capital city of Turkey. Located in the central part of Anatolia, the city has a population of over 5,200,000 in its urban center and 5,864,049 in Ankara Province (total of 25 districts). Ankara is Turkey's second-largest city by population after Istanbul.

Ankara was historically known as Ancyra and Angora. Serving as the capital of the ancient Celtic state of Galatia (280–64 BC), and later of the Roman province with the same name (25 BC–7th century), Ankara has various Hattian, Hittite, Lydian, Phrygian, Galatian, Greek, Persian, Roman, Byzantine, and Ottoman archeological sites. The Ottomans made the city the capital first of the Anatolia Eyalet (1393 – late 15th century) and then the Angora Eyalet (1827–1864) and the Angora Vilayet (1867–1922). On 23 April 1920, the Grand National Assembly of Turkey was established in Ankara, which became the headquarters of the Turkish National Movement during the Turkish War of Independence. Ankara became the new Turkish capital upon the establishment of the Republic on 29 October 1923, succeeding in this role as the former Ottoman capital Istanbul following the fall of the Ottoman Empire.
