Christopher Columbus was an Italian explorer and navigator from the Republic of Genoa who completed four Spanish-based voyages across the Atlantic Ocean sponsored by the Catholic Monarchs, opening the way for the widespread European exploration and European colonization of the Americas.

Central America is a subregion of North America. Its political boundaries are defined as bordering Mexico to the north, Colombia to the south, the Caribbean Sea to the east, and the Pacific Ocean to the west. 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 northern Guatemala to central 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.
Latin America is a collective region of the Americas where Romance languages—languages derived from Latin—are predominantly spoken. The term was coined in France in the mid-19th century to refer to regions in the Americas that were ruled by the Spanish, Portuguese, and French empires.

Native Americans, sometimes called American Indians, First Americans, or Indigenous Americans, are the Indigenous peoples of the United States or portions thereof, such as American Indians from the contiguous United States and Alaska Natives. The United States Census Bureau defines Native American as "all people indigenous to the United States and its territories, including Native Hawaiian and Other Pacific Islanders, whose data are published separately from American Indians and Alaska Natives". The U.S. census tracks data from American Indians and Alaska Native separately from Native Hawaiian and other Pacific Islanders, who include Samoan Americans and Chamorros.
South America is a continent entirely in the Western Hemisphere and mostly in the Southern Hemisphere, with a considerably smaller portion in the Northern Hemisphere. It can also be described as the southern subregion of the Americas.
The Americas, sometimes collectively called America, are a landmass comprising the totality of North and South America. The Americas make up most of the land in Earth's Western Hemisphere and comprise the New World.
The War of 1812, called the American War of 1812 in Britain, was fought by the United States and its indigenous allies against the United Kingdom and its own indigenous allies in British North America, with limited participation by Spain in Florida. It began when the United States declared war on Britain on 18 June 1812. Although peace terms were agreed upon in the December 1814 Treaty of Ghent, the war did not officially end until the peace treaty was ratified by the United States Congress on 17 February 1815.
The United States of America, commonly known as the United States or America, is a country primarily located in North America, between Canada and Mexico. It is a federation of 50 states, a federal capital district, and 326 Indian reservations. Outside the union of states, it asserts sovereignty over five major unincorporated island territories and various uninhabited islands. The country has the world's third-largest land area, largest maritime exclusive economic zone, and the third-largest population, exceeding 334 million.
The CONCACAF Champions Cup is an annual continental club football competition organized by CONCACAF. The tournament is contested by clubs from North America, Central America, and the Caribbean. The winner of the CONCACAF Champions Cup automatically qualifies for the FIFA Club World Cup.
A continent is any of several large geographical regions. Continents are generally identified by convention rather than any strict criteria. A continent could be a single landmass or a part of a very large landmass, as in the case of Asia or Europe. Due to this, the number of continents varies; up to seven or as few as four geographical regions are commonly regarded as continents. Most English-speaking countries recognize seven regions as continents. In order from largest to smallest in area, these seven regions are Asia, Africa, North America, South America, Antarctica, Europe, and Australia. Different variations with fewer continents merge some of these regions; examples of this are merging North America and South America into America, Asia and Europe into Eurasia, and Africa, Asia, and Europe into Afro-Eurasia.
