List of national capitals by population in the context of "Ngerulmud"

Vatican City, officially the Vatican City State (Italian: Stato della Città del Vaticano; Latin: Status Civitatis Vaticanae), often shortened as the Vatican, is a landlocked sovereign city-state. Ruled by the pope, it is an enclave within Rome and serves as the administrative centre of the Catholic Church. Vatican City is governed by the See of Rome, commonly known as the Holy See, itself a sovereign entity under international law, which maintains its temporal power, governance, diplomacy, and spiritual independence. Vatican is also used as a metonym for the Holy See, which is the central governing body of the Catholic Church and Vatican City, comprising the pope and the Roman Curia. The independent state of Vatican City came into existence in 1929 via the Lateran Treaty between the Holy See and the Kingdom of Italy, which spoke of it as a new creation, not as a vestige of the much larger Papal States (756–1870), which had previously encompassed much of Central Italy.

With an area of 48.99 hectares (121 acres) and a population of about 882 in 2024, it is the smallest sovereign state in the world both by area and by population. It is among the least populated capitals in the world. As governed by the Holy See, Vatican City State is an ecclesiastical or sacerdotal-monarchical state ruled by the pope, who is the bishop of Rome and head of the Catholic Church; the highest state functionaries are all Catholic clergy of various origins. The Holy See dates to early Christianity and is the principal episcopal see of the Catholic Church, which in 2018 had about 1.329 billion baptized Catholics in the world, in the Latin Church and 23 Eastern Catholic Churches. After the Avignon Papacy (1309–1377) the popes have mainly resided at the Apostolic Palace within what is now Vatican City, although at times residing instead in the Quirinal Palace in Rome or elsewhere.

Nuuk (Greenlandic pronunciation: [nuːk] ; Danish: Nuuk, formerly Godthåb [ˈkʌtˌhɔˀp]) is the capital and most populous city of Greenland, an autonomous territory in the Kingdom of Denmark. Nuuk is the seat of government and the territory's largest cultural and economic center. It is also the seat of government for the Sermersooq municipality. In January 2025, it had a population of 20,113—more than a third of the territory's population—making it one of the smallest capital cities in the world by population.

The city was founded in 1728 by the Danish-Norwegian missionary Hans Egede when he relocated from the earlier Hope Colony (Haabets Koloni), where he had arrived in 1721; the governor Claus Paarss was part of the relocation. The new colony was placed at the Inuit settlement of Nûk and named Godthaab ("Good Hope"). "Nuuk" is the Greenlandic word for "cape" and is commonly found in Greenlandic place names. It is so named because of its position at the end of the Nuup Kangerlua fjord on the Labrador Sea's eastern shore. Its latitude, at 64°11' N, makes it the world's northernmost capital, a few kilometres farther north than Reykjavík. When home rule was established in 1979, the authorization of place names was transferred to Greenlandic authorities, who preferred Greenlandic names to Danish ones. The name Godthåb mostly went out of use over the next two decades.

Beijing, previously romanized as Peking, is the capital city of China. With more than 22 million residents, it is the world's most populous national capital city, as well as China's second largest city by urban area, after Shanghai. It is located in Northern China, and is governed as a municipality under the direct administration of the State Council with 16 urban, suburban, and rural districts. Beijing is mostly surrounded by Hebei Province and neighbors Tianjin to the southeast; together, the three divisions form the Jing-Jin-Ji cluster.

Beijing is a global city and one of the world's leading centres for culture, diplomacy, politics, finance, business and economics, education, research, language, tourism, media, sport, science and technology, transportation, and art. It is home to the headquarters of most of China's largest state-owned companies and houses the largest number of Fortune Global 500 companies in the world, as well as the world's four biggest financial institutions by total assets. It is also a major hub for the national highway, expressway, railway, and high-speed rail networks. For a decade before the COVID-19 pandemic, Beijing Capital International Airport was Asia's busiest airport (2009–2019) and the second busiest airport in the world (2010–2019). In 2020, the Beijing subway was the fourth busiest and second longest in the world. Beijing Daxing International Airport, Beijing's second international airport, is the largest single-structure airport terminal in the world. The city has hosted numerous international and national sporting events, the most notable being the 2008 Summer Olympics and 2008 Summer Paralympics Games. In 2022, Beijing became the first city ever to host both the Summer and Winter Olympics, and also the Summer and Winter Paralympics.

The City of San Marino (Italian: Città di San Marino), also known simply as San Marino and locally as Città, is the capital city of the Republic of San Marino and one of its nine castelli. It has a population of 4,118. It is on the western slopes of San Marino's highest point, Monte Titano. It is also the fifth-least-populated national capital in the world.

Kinshasa (/kɪnˈʃɑːsə/; French: [kinʃasa]; Lingala: Kinsásá), formerly named Léopoldville from 1881–1966 (Dutch: Leopoldstad), is the capital and largest city of the Democratic Republic of the Congo. Kinshasa is one of the world's fastest-growing megacities, with an estimated population of 17.8 million in 2024. It is the most densely populated city in the DRC, the third-most populous city and third-largest metropolitan area in Africa, and the world's twenty-second most populous city and fourth-most populous capital city. It is the leading economic, political, and cultural center of the DRC, housing several industries including manufacturing, telecommunications, banking, and entertainment. The city also hosts some of the DRC's significant institutional buildings, such as the People's Palace, Palace of the Nation, Court of Cassation, Constitutional Court, African Union City, Marble Palace, Martyrs Stadium, Government House, Kinshasa Financial Center, and other national departments and agencies.

The Kinshasa site has been inhabited by Teke and Humbu people for centuries and was known as Nshasa before transforming into a commercial hub during the 19th and 20th centuries. The city was named Léopoldville by Henry Morton Stanley in honor of Leopold II of Belgium. The name was changed to Kinshasa in 1966 during Mobutu Sese Seko's Zairianisation campaign as a tribute to Nshasa village. Covering 9,965 square kilometers, Kinshasa stretches along the southern shores of the Pool Malebo on the Congo River. It forms an expansive crescent across flat, low-lying terrain at an average altitude of about 300 meters. Kinshasa borders the Mai-Ndombe Province, Kwilu Province, and Kwango Province to the east; the Congo River delineates its western and northern perimeters, constituting a natural border with the Republic of the Congo; to the south lies the Kongo Central Province. Across the river sits Brazzaville, the smaller capital of the neighboring Republic of the Congo, forming the world's closest pair of capital cities despite being separated by a four-kilometer-wide unbridged span of the Congo River.
