World Political Geography: Continents

Beyond Europe and South America, UPSC's continent-by-continent political geography draws most heavily on Africa: its colonial-boundary legacy, its landlocked states, and its regional groupings. A second recurring cluster sits in Asia beyond India (Central Asia and ASEAN), and a smaller but real one covers North America's odd political corners (Greenland, the Caribbean) and the Pacific. This note builds that continent-by-continent picture. For longitude, local time, the International Date Line, world trade choke points, and the Europe/South America facts already covered (Vatican City, San Marino, Liechtenstein, the EU/Eurozone/Schengen distinction, Bolivia and Paraguay, French Guiana, the Andes and the Amazon basin), see World Political Geography and Time Zones.

Africa: the colonial-boundary legacy

Most of Africa's present-day international borders were not drawn by Africans. The Berlin Conference (also called the Berlin West Africa Conference), held from November 1884 to February 1885, brought together fourteen European powers and the United States to agree the rules under which Africa would be partitioned among European colonisers, the so-called Scramble for Africa. No African ruler or representative was present. The lines the conference and the decades of colonial administration that followed drew across the map were frequently straight latitude or longitude marks on imprecise surveys, chosen for administrative convenience between colonial powers rather than for any correspondence with the ethnic, linguistic or kingdom boundaries already on the ground. Estimates put the number of pre-existing African societies and polities split across two or more colonial (and later national) territories at close to 190.

The consequence that UPSC cares about is not the history lesson itself but its long afterlife: post-independence Africa inherited these straight-line borders more or less intact, under the African Union's own founding principle (carried over from the OAU) of respecting colonial-era boundaries rather than reopening them. A single ethnic or linguistic community split across two or more states, and a single state containing several communities with no shared pre-colonial history of living under one government, are both direct products of this settlement, and both recur as an explanation offered for boundary disputes, secessionist movements and civil conflict across the continent. This is why "colonial cartography" is treated as a standing, testable cause in African political geography, not just background colour.

Africa: landlocked states, the African Union, and its border geography

Africa has 16 landlocked countries, the largest concentration of landlocked states of any continent: Botswana, Burkina Faso, Burundi, Central African Republic, Chad, Eswatini, Ethiopia, Lesotho, Malawi, Mali, Niger, Rwanda, South Sudan, Uganda, Zambia and Zimbabwe. Ethiopia is a notable case within this list: it lost its own Red Sea coastline when Eritrea became independent in 1993, making it Africa's most populous landlocked country. South Sudan is the newest addition, landlocked since its own independence from Sudan in 2011.

The continent's premier political organisation is the African Union (AU), launched in July 2002 at Durban, South Africa, replacing the Organisation of African Unity (OAU), which had run from 1963. The AU is headquartered at Addis Ababa, Ethiopia, and comprises 55 member states, every sovereign African state plus the Sahrawi Arab Democratic Republic (Western Sahara). Morocco is the pointed exception that UPSC has tested indirectly through Western Sahara: Morocco left the OAU in 1984 in protest at the organisation admitting the SADR as a member, and stayed outside continental Africa's main body for 33 years before rejoining the AU in January 2017, making it the AU's 55th member even as the SADR it had objected to remains a member too.

Africa also carries some of the world's most striking enclave and exclave geography, distinct from (and additional to) the Vatican City/San Marino/Liechtenstein cluster already covered for Europe. Lesotho is entirely surrounded by a single country, South Africa, making it one of only three countries on earth completely enclosed within one other state (the other two, Vatican City and San Marino, sit inside Italy). Cabinda is an exclave of Angola, a major oil-producing province separated from the rest of Angola by a narrow strip of the Democratic Republic of the Congo that gives the DRC its own short Atlantic coastline. Ceuta and Melilla, two Spanish autonomous cities on Morocco's Mediterranean coast, are Spanish exclaves (and the only EU territory on the African mainland) that Morocco has disputed since its own independence in 1956. Walvis Bay, Namibia's main deep-water port, was itself a South African exclave for decades under colonial-era administration; South Africa transferred sovereignty to Namibia only in 1994, four years after Namibian independence. And the Gambia, a narrow strip of land following the Gambia River and surrounded by Senegal on three landward sides plus a short Atlantic coastline, is the result of a 19th-century British-French colonial compromise over control of the river, often described as "almost an enclave" of Senegal despite being a fully sovereign state.

Asia beyond India: Central Asia and ASEAN

Central Asia's "five stans", Kazakhstan, Uzbekistan, Turkmenistan, Kyrgyzstan and Tajikistan, are all landlocked, former Soviet republics that became independent in 1991. Kazakhstan and Turkmenistan border the Caspian Sea, but the Caspian is the world's largest inland body of water rather than an open sea with ocean access, so bordering it does not remove landlocked status. Uzbekistan carries a distinctive fact: it is one of only two doubly landlocked countries in the world, meaning every country that borders it (Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan and Afghanistan) is itself landlocked. The only other doubly landlocked country anywhere is Liechtenstein, already covered in the Europe note; Uzbekistan has held this status since its own 1991 independence.

ASEAN (the Association of Southeast Asian Nations) was founded on 8 August 1967 in Bangkok by five founding members: Indonesia, Malaysia, the Philippines, Singapore and Thailand. Brunei joined in 1984, Vietnam in 1995, Laos and Myanmar together in 1997, Cambodia in 1999, and Timor-Leste became the newest and eleventh member in October 2025. Of these, Laos is the only landlocked ASEAN member, bordered by five other Southeast Asian states, a mirror of the "single landlocked member in an otherwise coastal grouping" pattern worth contrasting with South America's two (Bolivia and Paraguay). ASEAN also spans two of the world's largest archipelagic states: Indonesia (commonly cited around 17,000 islands) and the Philippines (commonly cited around 7,000 islands), both instructive contrasts with ASEAN's mainland Southeast Asian members (Myanmar, Thailand, Laos, Cambodia, Vietnam).

North America's political corners: Greenland, the Caribbean, Central America

Greenland, geographically part of North America and the world's largest island, is politically an autonomous territory within the Kingdom of Denmark, a European country, a genuine "which continent does this belong to" trap. It joined the European Community alongside Denmark in 1973, but after gaining home rule in 1979, Greenlanders voted to leave and formally exited in 1985; today it sits outside the EU as an Overseas Country and Territory associated with it, even though Greenlanders remain EU citizens by virtue of their Danish nationality. A further round of self-government began in 2009, but defence and foreign affairs remain with Denmark.

The Caribbean, together known as the West Indies, is conventionally split into three groupings. The Greater Antilles, the larger islands including Cuba, Jamaica, Hispaniola (shared by Haiti and the Dominican Republic) and Puerto Rico, make up roughly 90% of the region's total land area and hold most of its population. The Lesser Antilles form a long north-south arc from the Virgin Islands down to Grenada, itself split into the Leeward Islands (the more northerly and westerly group, including Antigua and Barbuda, Saint Kitts and Nevis, and Guadeloupe) and the Windward Islands (ranging south from Dominica to Grenada, more exposed to the prevailing trade winds). A third grouping, the Lucayan Archipelago, comprising the Bahamas and the Turks and Caicos Islands, sits apart from both Antilles chains.

Central America is the seven-state isthmus linking Mexico to Colombia: Belize, Guatemala, Honduras, El Salvador, Nicaragua, Costa Rica and Panama, separating the Pacific Ocean from the Caribbean Sea. Most of these states front both oceans; the two exceptions worth remembering are Belize (Caribbean coast only) and El Salvador (Pacific coast only, the region's only state without a Caribbean coastline). Panama's own strategic weight, via the Panama Canal, is covered in the choke-points table in the linked time-zones note.

Australia and Oceania: the Pacific groupings

The Pacific islands beyond Australia and New Zealand are conventionally divided into three cultural-geographic regions. Melanesia, north and east of Australia, includes Papua New Guinea, Fiji, the Solomon Islands, Vanuatu and New Caledonia. Micronesia, north of the equator and east of the Philippines, includes the Federated States of Micronesia, Palau, the Marshall Islands, Kiribati, Nauru and Guam. Polynesia, the eastern and largest region by area, is loosely bounded by a triangle running from Hawaii to New Zealand to Easter Island, and includes Samoa, Tonga, the Cook Islands and French Polynesia.

Sovereignty status varies sharply within this region, a favourite UPSC "which of these is/is not independent" angle. New Caledonia (in Melanesia) and French Polynesia (in Polynesia) remain French overseas territories, not independent states. The Cook Islands and Niue, by contrast, are self-governing states in "free association" with New Zealand: they run their own domestic affairs and their people hold New Zealand citizenship, while New Zealand continues to represent them in most diplomatic and defence matters. Guam and the Northern Mariana Islands, in Micronesia, remain United States territories. Fiji sits at a cultural crossroads, geographically part of Melanesia but with strong historical and linguistic ties to Polynesia, a detail that has shown up as a direct statement-based trap.

The Caucasus: a fresh cluster beyond Europe's western micro-states

Georgia, Armenia and Azerbaijan make up the Caucasus, a mountainous, transcontinental region between the Black Sea and the Caspian Sea often treated as marking part of the boundary between Europe and Asia. The region's standing dispute is Nagorno-Karabakh, a mountainous area that lies within Azerbaijan's internationally recognised borders but was, for decades, populated mostly by ethnic Armenians and administered as a self-declared, Armenia-backed entity following a war in the early 1990s. A 2020 war ended in a Russian-brokered ceasefire under which Armenia relinquished military control and Russian peacekeepers deployed to the region; in a swift 2023 military operation, Azerbaijan brought the entire territory back under its direct control, effectively ending Nagorno-Karabakh's decades of separate administration. The dispute is a useful case study in the gap between de facto control and de jure sovereignty, the same distinction worth carrying into the Balkans.

The Balkans, the mountainous peninsula of southeastern Europe, are home to the states that emerged from the breakup of Yugoslavia (Slovenia, Croatia, Bosnia and Herzegovina, Serbia, Montenegro, North Macedonia and Kosovo) alongside Albania, Bulgaria, Romania and Greece. Kosovo carries UPSC's clearest "partial recognition" example anywhere in the world: it unilaterally declared independence from Serbia in February 2008, and while it has since been recognised by around 110 of the UN's 193 member states, Serbia does not recognise it and continues to claim it as an autonomous province, and Kosovo itself is not a UN member state. The 2010 International Court of Justice opinion that the declaration did not violate international law did not change Serbia's position. This statement, "recognised by many states but not a UN member and not recognised by the state it separated from," is worth holding onto as a template UPSC can apply to any partially recognised territory, not just Kosovo.

Quick revision points

• The Berlin Conference (1884-85) partitioned Africa among European powers with no African representation, splitting close to 190 pre-existing societies across arbitrary, mostly straight-line borders that independent African states inherited largely unchanged.
• Africa has 16 landlocked states, more than any other continent; Ethiopia lost its coastline when Eritrea became independent in 1993, and South Sudan has been landlocked since its own 2011 independence.
• The African Union (2002, Addis Ababa) replaced the OAU (1963-2002) and has 55 members. Morocco left the OAU in 1984 over Western Sahara's (SADR's) admission and rejoined the AU only in 2017.
• Lesotho is one of only three countries entirely enclosed within a single other state (with Vatican City and San Marino). Cabinda is an Angolan exclave cut off by the DRC; Ceuta and Melilla are Spanish exclaves in Morocco; Walvis Bay was a South African exclave in Namibia until 1994; the Gambia is nearly enclaved by Senegal.
• Central Asia's five "stans" are all landlocked. Uzbekistan and Liechtenstein are the world's only two doubly landlocked countries.
• ASEAN (founded 1967, 5 founders, now 11 members after Timor-Leste joined in 2025) has Laos as its only landlocked member; Indonesia and the Philippines are its two major archipelagic states.
• Greenland is geographically North American but politically an autonomous Danish territory outside the EU.
• The Caribbean splits into the Greater Antilles, the Lesser Antilles (Leeward and Windward Islands), and the Bahamas-based Lucayan Archipelago. Central America's seven states are Belize, Guatemala, Honduras, El Salvador, Nicaragua, Costa Rica and Panama; Belize has only a Caribbean coast and El Salvador only a Pacific one.
• Oceania splits into Melanesia, Micronesia and Polynesia. New Caledonia and French Polynesia are French territories; the Cook Islands and Niue are self-governing states in free association with New Zealand.
• Nagorno-Karabakh lies inside Azerbaijan's recognised borders but was contested by Armenia for decades; Azerbaijan retook full control in 2023. Kosovo, recognised by about 110 states but not a UN member and not recognised by Serbia, is UPSC's clearest partial-recognition case.

This chapter rewards knowing which fact belongs to which continent under pressure, since options in a matching question are often plausible for a neighbouring region too. Anchor each fact to its region (an African exclave is not a Caribbean one) before moving to the practice set below.
