Pan-Americanism is a movement which, through diplomatic, political, economic and social means, seeks to create, encourage and organize relationships, associations and cooperation between the states of the Americas in common interests.

The struggle for independence after 1810 by the Latin American nations evoked a sense of unity, especially in South America where, under Simón Bolívar in the north and José de San Martín in the south, there were cooperative efforts. Francisco Morazán briefly headed a Federal Republic of Central America. Early South American Pan-Americanists were also inspired by the American Revolutionary War, where a suppressed and colonized society struggled united and gained its independence. In the United States, Henry Clay and Thomas Jefferson set forth the principles of Pan-Americanism in the early 19th century, and soon afterward the United States declared through the Monroe Doctrine a new policy with regard to interference by European nations in the affairs of America.

The United Nations Conference on Environment and Development (UNCED), also known as the Rio Summit, Rio Conference, Earth Summit (Portuguese: Eco '92) was a major United Nations conference held in Rio de Janeiro from 3 June to 14 June 1992.

172 governments participated, with 108 sending their heads of state or government. Some 2,400 representatives of non-governmental organizations (NGOs) attended, with 17,000 people at the parallel NGO "Global Forum" (a.k.a. Forum Global), who had Consultative Status.

The issues addressed included:

An important achievement was an agreement on the Climate Change Convention which in turn led to the Kyoto Protocol. Another agreement was to "not carry out any activities on the lands of indigenous peoples that would cause environmental degradation or that would be culturally inappropriate".

The Convention on Biological Diversity was opened for signature at the Earth Summit, and made a start towards redefinition of measures that did not inherently encourage destruction of natural ecoregions and so-called uneconomic growth.

Carmen Miranda, GCIH (Portuguese pronunciation: [ˈkaɾmẽȷ̃ miˈɾɐ̃dɐ], 9 February 1909 – 5 August 1955) was a Portuguese-born Braziliansamba singer, Broadway actress and Hollywood film star popular in the 1940s and 1950s. She was, by some accounts, the highest-earning woman in the United States and noted for her signature fruit hat outfit she wore in the 1943 movie The Gang's All Here. Though hailed as a talented performer, her movie roles in the United States soon became cartoonish and she grew to resent them. She is considered the precursor of Brazil's Tropicalismo.

Carmen Miranda was born Maria do Carmo Miranda da Cunha in Várzea da Ovelha e Aliviada, a village in the northern Portuguese municipality of Marco de Canaveses. She was the second daughter of José Maria Pinto da Cunha (17 February 1887 – 21 June 1938) and Maria Emília Miranda (10 March 1886 – Rio de Janeiro, 9 November 1971). In 1909 when she was 10-months old, her father emigrated alone to Brazil and settled in Rio de Janeiro, where he opened a barber shop. Her mother followed in 1910 with their daughters Olinda and Maria do Carmo. Maria do Carmo, later Carmen, never returned to Portugal, but retained her Portuguese nationality. In Brazil, her parents had four more children: Amaro (1911), Cecília (1913), Aurora (1915–2005) and Óscar (1916).

Sir Winston Leonard Spencer-Churchill, KG, OM, CH, TD, PC, DL, FRS, Hon. RA (30 November 1874 – 24 January 1965) was a British Conservative politician and statesman known for his leadership of the United Kingdom during the Second World War. Widely regarded as one of the greatest wartime leaders of the century, he served as Prime Minister twice (1940–45 and 1951–55). A noted statesman and orator, Churchill was also an officer in the British Army, a historian, a writer, and an artist. He is the only British prime minister to have received the Nobel Prize in Literature, and was the first person to be made an Honorary Citizen of the United States.

Churchill was born into the aristocratic family of the Dukes of Marlborough. His father, Lord Randolph Churchill, was a charismatic politician who served as Chancellor of the Exchequer; his mother, Jenny Jerome, was an American socialite. As a young army officer, he saw action in British India, the Sudan, and the Second Boer War. He gained fame as a war correspondent and wrote books about his campaigns.
