Colonialism is the establishment, maintenance, acquisition and expansion of colonies in one territory by people from another territory. It is a process whereby the metropole claims sovereignty over the colony, and the social structure, government, and economics of the colony are changed by colonizers from the metropole. Colonialism is a set of unequal relationships between the metropole and the colony and between the colonists and the indigenous population.

The colonial period was the era from the 1550s to, arguably, the 1990s when several European powers (Spain, Portugal, Britain, and France especially) established colonies in Asia, Africa, and the Americas. At first the countries followed mercantilist policies designed to strengthen the home economy at the expense of rivals, so the colonies were usually allowed to trade only with the mother country. By the mid-19th century, however, the powerful British Empire gave up mercantilism and trade restrictions and introduced the principle of free trade, with few restrictions or tariffs.

James Earl "Jimmy" Carter, Jr. (born October 1, 1924) is an American politician who served as the 39th President of the United States (1977–1981) and was the recipient of the 2002 Nobel Peace Prize, the only U.S. President to have received the Prize after leaving office. Before he became President, Carter served as a U.S. Naval officer, was a peanut farmer, served two terms as a Georgia State Senator and one as Governor of Georgia (1971–1975).

During Carter's term as President, two new cabinet-level departments were created: the Department of Energy and the Department of Education. He established a national energy policy that included conservation, price control, and new technology. In foreign affairs, Carter pursued the Camp David Accords, the Panama Canal Treaties, the second round of Strategic Arms Limitation Talks (SALT II), and returned the Panama Canal Zone to Panama. Throughout his career, Carter strongly emphasized human rights. He took office during a period of international stagflation, which persisted throughout his term. The end of his presidential tenure was marked by the 1979–1981 Iran hostage crisis, the 1979 energy crisis, the Three Mile Island nuclear accident, the Soviet invasion of Afghanistan (at the end of 1979), 1980 Summer Olympics boycott by the United States of the Moscow Olympics and the 1980 eruption of Mount St. Helens.
