The history of Argentina is divided by historians into four main parts: the pre-Columbian time or early history (up to the sixteenth century), the colonial period (roughly 1516 to 1810), the independence wars and the early post-colonial period of the nation (1810 to 1880) and the history of modern Argentina (from around 1880).

The beginning of prehistory in the present territory of Argentina began with the first human settlements on the southern tip of Patagonia around 13,000 years ago. Written history began with the arrival of Spanish chroniclers with the expedition of Juan Díaz de Solís in 1516 to Río de la Plata river, which marks the beginning of Spanish domination in this region. In 1776 the Spanish Crown established the Viceroyalty of the Río de la Plata, an umbrella of territories from which, with the Revolution of May 1810, began a process of gradual formation of several independent states, including one called the United Provinces of Río de la Plata. With the declaration of independence on July 9, 1816 and the military defeat of the Spanish Empire in 1824, a federal state was formed in 1853-1861, known today as the Republic of Argentina.

Argentina ⁱ/ˌɑrdʒənˈtiːnə/, officially the Argentine Republic (Spanish: República Argentina [reˈpuβlika aɾxenˈtina]), is a country in South America, the continent's second largest by land area, after Brazil. It is constituted as a federation of 23 provinces and an autonomous city, Buenos Aires. It is the eighth-largest country in the world by land area and the largest among Spanish-speaking nations.

Argentina's continental area is between the Andes mountain range in the west and the Atlantic Ocean in the east. It borders Paraguay and Bolivia to the north, Brazil and Uruguay to the northeast, and Chile to the west and south. Argentine claims over Antarctica, as well as overlapping claims made by Chile and the United Kingdom, are suspended by the Antarctic Treaty of 1961. Argentina also claims the Falkland Islands (Spanish: Islas Malvinas) and South Georgia and the South Sandwich Islands, which are administered by the United Kingdom as British Overseas Territories.

A recognised middle power, Argentina is Latin America's third-largest economy, with a "very high" rating on the Human development index. Within Latin America, Argentina has the fifth highest nominal GDP per capita and the highest in purchasing power terms. Analysts have argued that the country has a "foundation for future growth due to its market size, levels of foreign direct investment, and percentage of high-tech exports as share of total manufactured goods", and it is classed by investors as middle emerging economy. Argentina is a founding member of the United Nations, Mercosur, the Union of South American Nations, the Organization of Ibero-American States, the World Bank Group and the World Trade Organization, and is one of the G-15 and G-20 major economies.

Eva Anna Paula Hitler (née Braun; 6 February 1912 – 30 April 1945) was the longtime companion of Adolf Hitler and, for less than 40 hours, his wife. Braun met Hitler in Munich when she was 17 years old, while she was working as an assistant and model for his personal photographer, and began seeing him often about two years later. She attempted suicide twice during their early relationship. By 1936, she was a part of his household at the Berghof near Berchtesgaden and lived a sheltered life throughout World War II. Braun was a photographer, and many of the surviving colour photographs and films of Hitler were taken by her. She was a key figure within Hitler's inner social circle, but did not attend public events with him until mid-1944, when her sister Gretl married Hermann Fegelein, the SS liaison officer on his staff.

As the Third Reich collapsed towards the end of the war, Braun swore loyalty to Hitler and went to Berlin to be by his side in the heavily reinforced Führerbunker beneath the Reich Chancellery. As Red Army troops fought their way into the neighbourhood on 29 April 1945, she married Hitler during a brief civil ceremony; she was 33 and he was 56. Less than 40 hours later, they committed suicide together in a sitting room of the bunker, she by biting into a capsule of cyanide. The German public was unaware of Braun's relationship with Hitler until after her death.
