Peru, officially the Republic of Peru, is a country in western South America. It is bordered to the north by Ecuador and Colombia, to the east by Brazil, to the southeast by Bolivia, to the south by Chile, and to the south and west by the Pacific Ocean. Peru is a megadiverse country, with habitats ranging from the arid plains of the Pacific coastal region in the west, to the peaks of the Andes mountains extending from the north to the southeast of the country, to the tropical Amazon basin rainforest in the east with the Amazon River. Peru has a population of over 32 million, and its capital and largest city is Lima. At 1,285,216 km (496,225 sq mi), Peru is the 19th largest country in the world, and the third largest in South America.

Peruvian territory was home to several cultures during the ancient and medieval periods, and has one of the longest histories of civilization of any country, tracing its heritage back to the 10th millennium BCE Caral–Supe civilization, the earliest civilization in the Americas and considered one of the cradles of civilization. Notable succeeding cultures and civilizations include the Nazca culture, the Moche, Wari and Tiwanaku empires, the Kingdom of Cusco, and the Inca Empire, the largest known state in the pre-Columbian Americas. The Spanish Empire conquered the region in the 16th century and Charles V established a viceroyalty with the official name of the Kingdom of Peru that encompassed most of its South American territories, with its capital in Lima. Higher education started in the Americas with the official establishment of the National University of San Marcos in Lima in 1551.

Venezuela, officially the Bolivarian Republic of Venezuela, is a country on the northern coast of South America, consisting of a continental landmass and many islands and islets in the Caribbean Sea. It comprises an area of 916,445 km (353,841 sq mi), and its population was estimated at 29 million in 2022. The capital and largest urban agglomeration is the city of Caracas. The continental territory is bordered on the north by the Caribbean Sea and the Atlantic Ocean, on the west by Colombia, Brazil on the south, Trinidad and Tobago to the north-east and on the east by Guyana. Venezuela consists of 23 states, the Capital District, and federal dependencies covering Venezuela's offshore islands. Venezuela is among the most urbanized countries in Latin America; the vast majority of Venezuelans live in the cities of the north and in the capital.

The territory of Venezuela was colonized by Spain in 1522, amid resistance from Indigenous peoples. In 1811, it became one of the first Spanish-American territories to declare independence from the Spanish and to form part of the first federal Republic of Colombia (Gran Colombia). It separated as a full sovereign country in 1830. During the 19th century, Venezuela suffered political turmoil and autocracy, remaining dominated by regional military dictators until the mid-20th century. From 1958, the country had a series of democratic governments, as an exception where most of the region was ruled by military dictatorships, and the period was characterized by economic prosperity.

Ecuador, officially the Republic of Ecuador, is a country in northwestern South America, bordered by Colombia on the north, Peru on the east and south, and the Pacific Ocean on the west. It also includes the Galápagos Province which contains the Galápagos Islands in the Pacific, about 1,000 kilometers (621 mi) west of the mainland. The country's capital is Quito and its largest city is Guayaquil.

The land that comprises modern-day Ecuador was once home to several groups of indigenous peoples that were gradually incorporated into the Inca Empire during the 15th century. The territory was colonized by the Spanish Empire during the 16th century, achieving independence in 1820 as part of Gran Colombia, from which it emerged as a sovereign state in 1830. The legacy of both empires is reflected in Ecuador's ethnically diverse population, with most of its 17.8 million people being mestizos, followed by large minorities of Europeans, Native American, African, and Asian descendants. Spanish is the official language spoken by a majority of the population, although 13 native languages are also recognized, including Quechua and Shuar.

The Andes (/ˈændiːz/ AN-deez), Andes Mountains or Andean Mountain Range (Spanish: Cordillera de los Andes; Quechua: Anti) are the longest continental mountain range in the world, forming a continuous highland along the western edge of South America. The range is 8,900 km (5,500 mi) long and 200 to 700 km (120 to 430 mi) wide (widest between 18°S and 20°S latitude) and has an average height of about 4,000 m (13,000 ft). The Andes extend from south to north through seven South American countries: Argentina, Chile, Bolivia, Peru, Ecuador, Colombia, and Venezuela.

Along their length, the Andes are split into several ranges, separated by intermediate depressions. The Andes are the location of several high plateaus—some of which host major cities such as Arequipa, Bogotá, Cali, Medellín, El Alto, La Paz, Mérida, Santiago and Sucre. The Altiplano Plateau is the world's second highest after the Tibetan Plateau. These ranges are in turn grouped into three major divisions based on climate: the Tropical Andes, the Dry Andes, and the Wet Andes.

The Amazon basin is the part of South America drained by the Amazon River and its tributaries. The Amazon drainage basin covers an area of about 7,000,000 km (2,700,000 sq mi), or about 35.5 percent of the South American continent. It is located in the countries of Bolivia, Brazil, Colombia, Ecuador, Guyana, Peru, Suriname, and Venezuela, as well as the territory of French Guiana.

Most of the basin is covered by the Amazon rainforest, also known as Amazonia. With a 6 million km (2.3 million sq mi) area of dense tropical forest, it is the largest rainforest in the world.

Below is a list of countries and dependencies in South America by area. Brazil is the largest country in South America while Suriname is the smallest.

Panama is not regarded as a transcontinental country but the country is sometimes included in South America due to being part of Colombia prior to its secession in 1903. The island of Trinidad is sometimes included in South America, which then makes Trinidad and Tobago a transcontinental country.

The Andean civilizations were South American complex societies of many indigenous people. They stretched down the spine of the Andes for 4,000 km (2,500 miles) from southern Colombia, to Ecuador and Peru, including the deserts of coastal Peru, to north Chile and northwest Argentina. Archaeologists believe that Andean civilizations first developed on the narrow coastal plain of the Pacific Ocean. The Caral or Norte Chico civilization of coastal Peru is the oldest known civilization in the Americas, dating back to 3500 BCE. Andean civilizations are one of at least five civilizations in the world deemed by scholars to be "pristine." The concept of a "pristine" civilization refers to a civilization that has developed independently of external influences and is not a derivative of other civilizations.

Despite the severe environmental challenges of high mountains and hyper-arid desert, the Andean civilizations domesticated a wide variety of crops, some of which, such as potatoes, peppers, peanuts, manioc, chocolate, and coca, became of worldwide importance. The Andean civilizations were noteworthy for monumental architecture, an extensive road system, textile weaving, and many unique characteristics of the societies they created.

The Inca Empire, officially known as the Realm of the Four Parts (Quechua: Tawantinsuyu pronounced [taˈwantiŋ ˈsuju], lit. 'land of four parts'), was the largest empire in pre-Columbian America. The administrative, political, and military center of the empire was in the city of Cusco. The Inca civilisation rose from the Peruvian highlands sometime in the early 13th century. The Portuguese explorer Aleixo Garcia was the first European to reach the Inca Empire in 1524. Later, in 1532, the Spanish began the conquest of the Inca Empire, and by 1572 the last Inca state was fully conquered.

From 1438 to 1533, the Incas incorporated a large portion of western South America, centered on the Andean Mountains, using conquest and peaceful assimilation, among other methods. At its largest, the empire joined modern-day Peru with what are now western Ecuador, western and south-central Bolivia, northwest Argentina, the southwesternmost tip of Colombia and a large portion of modern-day Chile, forming a state comparable to the historical empires of Eurasia. Its official language was Quechua.

The Caribbean Sea is a sea of the North Atlantic Ocean in the tropics of the Western Hemisphere, located south of the Gulf of Mexico and southwest of the Sargasso Sea. It is bounded by the Greater Antilles to the north from Cuba to Puerto Rico, the Lesser Antilles to the east from the Virgin Islands to Trinidad and Tobago, South America to the south from the Venezuelan coastline to the Colombian coastline, and Central America and the Yucatán Peninsula to the west from Panama to Mexico. The geopolitical region around the Caribbean Sea, including the numerous islands of the West Indies and adjacent coastal areas in the mainland of the Americas, is known as the Caribbean.

The Caribbean Sea is one of the largest seas on Earth and has an area of about 2,754,000 km (1,063,000 sq mi). The sea's deepest point is the Cayman Trough, between the Cayman Islands and Jamaica, at 7,686 m (25,217 ft) below sea level. The Caribbean coastline has many gulfs and bays: the Gulf of Gonâve, the Gulf of Venezuela, the Gulf of Darién, Golfo de los Mosquitos, the Gulf of Paria and the Gulf of Honduras.

New Spain, officially the Viceroyalty of New Spain (Spanish: Virreinato de Nueva España [birejˈnato ðe ˈnweβa esˈpaɲa] ; Nahuatl: Yankwik Kaxtillan Birreiyotl), originally the Kingdom of New Spain, was an integral territorial entity of the Spanish Empire, established by Habsburg Spain. It was one of several domains established during the Spanish conquest of the Americas, and had its capital in Mexico City. Its jurisdiction comprised a large area of the southern and western portions of North America, mainly what became Mexico and the Southwestern United States, but also California, Florida and Louisiana; Central America (as part of Mexico); the Caribbean like Hispaniola and Martinique, and northern parts of South America, even Colombia; several Pacific archipelagos, including the Philippines and Guam. Additional Asian colonies included "Spanish Formosa", on the island of Taiwan.

After the 1521 Spanish conquest of the Aztec Empire, conqueror Hernán Cortés named the territory New Spain, and established the new capital, Mexico City, on the site of Tenochtitlan, the capital of the Aztec Empire. Central Mexico became the base of expeditions of exploration and conquest, expanding the territory claimed by the Spanish Empire. With the political and economic importance of the conquest, the crown asserted direct control over the densely populated realm. The crown established New Spain as a viceroyalty in 1535, appointing as viceroy Antonio de Mendoza, an aristocrat loyal to the monarch rather than the conqueror Cortés. New Spain was the first of the viceroyalties that Spain created, the second being Peru in 1542, following the Spanish conquest of the Inca Empire. Both New Spain and Peru had dense indigenous populations at conquest as a source of labor and material wealth in the form of vast silver deposits, discovered and exploited beginning in the mid-1600s.

Central America is a subregion of North America. Its political boundaries are defined as bordering Mexico to the north, Colombia to the southeast, the Caribbean to the east, and the Pacific Ocean to the southwest. Central America is usually defined as consisting of seven countries: Belize, Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua, and Panama. Within Central America is the Mesoamerican biodiversity hotspot, which extends from southern Mexico to southeastern Panama. Due to the presence of several active geologic faults and the Central America Volcanic Arc, there is a high amount of seismic activity in the region, such as volcanic eruptions and earthquakes, which has resulted in death, injury, and property damage.

Most of Central America falls under the Isthmo-Colombian cultural area. Before the Spanish expedition of Christopher Columbus' voyages to the Americas, hundreds of indigenous peoples made their homes in the area. From the year 1502 onwards, Spain began their colonization. From 1609 to 1821, the majority of Central American territories (except for what would become Belize and Panama and including the modern Mexican state of Chiapas) were governed by the viceroyalty of New Spain from Mexico City as the Captaincy General of Guatemala. On 24 August 1821, Spanish Viceroy Juan de O'Donojú signed the Treaty of Córdoba, which established New Spain's independence and autonomy from mainland Spain. On 15 September, the Act of Independence of Central America was enacted to announce Central America's separation from the Spanish Empire. Some of New Spain's provinces in the Central American region were invaded and annexed to the First Mexican Empire; however in 1823 they seceded from Mexico to form the Federal Republic of Central America until 1838.

Territories of the United States are subnational geographical and political areas governed as administrative divisions and dependent territories under the sovereignty of the United States. Despite all being subject to the constitutional and territorial jurisdiction of the U.S. federal government, territories differ from states and Indian reservations in that they are not inherently sovereign. While states have dual sovereignty and Native American tribes have tribal sovereignty in relation to the federal government, the self-governing powers of territories ultimately derive from the U.S. Congress, as per the Territorial Clause in Article IV of the U.S. Constitution. Territories are classified as "organized" or "unorganized" depending on whether they operate under an organic act, and "incorporated" or "unincorporated" depending on whether the U.S. Constitution applies fully or partially to them. As areas belonging to, but not integral parts of, the U.S., territories are their own distinct nations centered around a collective identity based on their land, history, ethnicity, culture, and language.

All territories of the U.S. are insular areas. The U.S. has sovereignty over three archipelagos or islands in the Caribbean Sea and eleven in the Pacific Ocean. Five territories (American Samoa, Guam, the Northern Mariana Islands, Puerto Rico, and the United States Virgin Islands) are permanently inhabited, unincorporated territories; the other nine are small islands, atolls, and reefs with no native (or permanent) population. Of the 14, only one is classified as an incorporated territory (Palmyra Atoll). Two additional territories (Bajo Nuevo Bank and Serranilla Bank) are claimed by the U.S. but administered by Colombia. Historically, territories were created to administer newly acquired land, and most eventually attained statehood. The most recent territory to become a U.S. state was Hawaii on August 21, 1959.

A megacity is a very large city, typically with a population of more than 10 million people. The United Nations Department of Economic and Social Affairs (UN DESA) in its "World Urbanization Prospects" report defines megacities as urban agglomerations with over 10 million inhabitants. A University of Bonn report holds that they are "usually defined as metropolitan areas with a total population of 10 million or more people". Elsewhere in other sources, from five to eight million is considered the minimum threshold, along with a population density of at least 2,000 per square kilometre. The terms conurbation, metropolis, and metroplex are also applied to the latter.

The total number of megacities in the world varies between different sources and their publication dates. The world had 32 according to EU Global Human Settlement Layer (in 2024), 33 according to UN DESA (in 2025), 39 according to the OECD, 42 according to Demographia (in 2025), and 45 according to CityPopulation.de (in 2023). The later two add 13 additional cities that are calculated outside the range otherwise. In total, at most 53 unique places are mentioned as megacities across these sources, although some of these are just agglomerated differently between them. A good percentage of these urban agglomerations are in China and India. The other three-to-five countries with more than one megacity are Brazil, Indonesia, Japan, Pakistan, and the United States. African megacities are present in Angola, Democratic Republic of the Congo, Egypt, Nigeria and South Africa; European megacities are present in France, Germany, Russia, the United Kingdom, and Turkey (also in Asia); megacities can be found in Latin America in the countries of Brazil, Mexico, Colombia, Peru, and Argentina.

São Paulo (/ˌsaʊ ˈpaʊloʊ/, Portuguese: [sɐ̃w ˈpawlu] ) is one of the 26 states of the Federative Republic of Brazil and is named after Saint Paul of Tarsus. It is located in the Southeast Region and is bordered by the states of Minas Gerais to the north and northeast, Paraná to the south, Rio de Janeiro to the east and Mato Grosso do Sul to the west, in addition to the Atlantic Ocean to the southeast. It is divided into 645 municipalities. The total area is 248,219.481 square kilometres (95,838.077 square miles) km, which is equivalent to 2.9% of Brazil's surface, being slightly larger than the United Kingdom. Its capital is the municipality of São Paulo.

With more than 44 million inhabitants in 2022, São Paulo is the most populous Brazilian state (around 22% of the Brazilian population), the world's 28th-most-populous sub-national entity and the most populous sub-national entity in the Americas, and the fourth-most-populous political entity of South America, surpassed only by the rest of the Brazilian federation, Colombia, and Argentina. The local population is one of the most diverse in the country and descended mostly from Italians, who began immigrating to the country in the late 19th century; the Portuguese, who colonized Brazil and installed the first European settlements in the region; Indigenous peoples, many distinct ethnic groups; Africans, who were brought from Africa as enslaved people in the colonial era and migrants from other regions of the country. In addition, Arabs, Armenians, Chinese, Germans, Greeks, Japanese, Spanish and American Southerners also are present in the ethnic composition of the local population.

Hurricane Harvey was a powerful and devastating tropical cyclone that made landfall in Texas and Louisiana in August 2017, causing catastrophic flooding and more than 100 deaths. It is tied with 2005's Hurricane Katrina as the costliest tropical cyclone on record, inflicting $125 billion (2017 USD) in damage, primarily from catastrophic rainfall-triggered flooding in Greater Houston and Southeast Texas; this made the storm the costliest natural disaster recorded in Texas at the time. It was the first major hurricane to make landfall in the United States since Wilma in 2005, ending a record 12-year span in which no hurricanes made landfall at the intensity of a major hurricane throughout the country. In a four-day period, many areas received more than 40 inches (1,000 mm) of rain as the system slowly meandered over eastern Texas and adjacent waters, causing unprecedented flooding. With peak accumulations of 60.58 in (1,539 mm) in Nederland, Texas, Harvey was the wettest tropical cyclone on record in the United States. The resulting floods inundated hundreds of thousands of homes, which displaced more than 30,000 people and prompted more than 17,000 rescues.

The eighth named storm, third hurricane, and first major hurricane of the extremely active 2017 Atlantic hurricane season, Harvey developed from a tropical wave to the east of the Lesser Antilles, reaching tropical storm status on August 17. The storm crossed through the Windward Islands on the following day, making landfall on the southern end of Barbados and a second landfall on Saint Vincent. Upon entering the Caribbean, Harvey began to weaken due to moderate wind shear, and degenerated into a tropical wave north of Colombia, late on August 19. The remnants were monitored for regeneration as it continued west-northwestward across the Caribbean and the Yucatán Peninsula, before redeveloping over the Bay of Campeche on August 23. Harvey then began to rapidly intensify on August 24, regaining tropical storm status and becoming a hurricane later that day.

Middle America is a subregion in the Northern Hemisphere tropics of the Americas. It usually includes Mexico, the seven countries of Central America, and the 13 island countries and 18 territories of the Caribbean. Together with Northern America, they form the continent of North America.

Colombia and Venezuela of Caribbean South America are sometimes included in this subregion. The Caribbean is occasionally excluded from this subregion while The Guianas are infrequently included.

The following is a list of sovereign countries and dependent territories in North America, a continent that covers the landmass north of the Colombia-Panama border as well as the islands of the Caribbean.

The Southern Common Market (commonly known by abbreviation Mercosur in Spanish and Mercosul in Portuguese) is a South American trade bloc established by the Treaty of Asunción in 1991 and Protocol of Ouro Preto in 1994. Its full members are Argentina, Bolivia, Brazil, Paraguay, and Uruguay. Venezuela is a full member but has been suspended since 1 December 2016. Chile, Colombia, Ecuador, Guyana, Panama, Peru, and Suriname are associate countries.

Mercosur's origins are linked to the discussions for the constitution of a regional economic market for Latin America, which go back to the treaty that established the Latin American Free Trade Association in 1960, which was succeeded by the Latin American Integration Association in the 1980s. At the time, Argentina and Brazil made progress in the matter, signing the Iguaçu Declaration (1985), which established a bilateral commission, which was followed by a series of trade agreements the following year. The Integration, Cooperation and Development Treaty, signed between both countries in 1988, set the goal of establishing a common market, which other Latin American countries could join. Paraguay and Uruguay joined the process and the four countries became signatories to the Treaty of Asunción (1991), which established the Southern Common Market, a trade alliance aimed at boosting the regional economy, moving goods, people among themselves, workforce and capital. Initially a free trade zone was established, in which the signatory countries would not tax or restrict each other's imports. As of 1 January 1995, this area became a customs union, in which all signatories could charge the same quotas on imports from other countries (common external tariff). The following year, Bolivia and Chile acquired membership status. Other Latin American nations have expressed interest in joining the group.

The West Indies are an island subregion of the Americas, surrounded by the North Atlantic Ocean and the Caribbean Sea, which comprises 13 independent island countries and 18 dependencies in three archipelagos: the Greater Antilles, the Lesser Antilles, and the Lucayan Archipelago.

The subregion includes all the islands in the Antilles, in addition to The Bahamas and the Turks and Caicos Islands, which are in the North Atlantic Ocean. The term is often interchangeable with "Caribbean", although the latter may also include coastal regions of Central and South American mainland nations, including Mexico, Belize, Honduras, Panama, Colombia, Venezuela, French Guiana, Guyana, and Suriname, as well as the Atlantic island nation of Bermuda, all of which are culturally related but geographically distinct from the three main island groups.
