The Spanish Civil War was a major conflict fought in Spain from 17 July 1936 to 1 April 1939. The war began after a pronunciamiento (declaration of opposition) by a group of generals under the leadership of José Sanjurjo against the elected government of the Second Spanish Republic, at the time under the leadership of President Manuel Azaña. The rebel coup was supported by a number of conservative groups including the Spanish Confederation of the Autonomous Right, monarchists such as the religious conservative Carlists, and the Fascist Falange. The uprising was authoritarian and anti-separatist in inspiration; anti-Basque and anti-Catalan feeling marked the Nationalist zone.

Following the only partially successful coup, Spain was left militarily and politically divided. From that moment onwards, general Francisco Franco began a protracted war of attrition against the established government for the control of the country. The rebel forces received the support of Nazi Germany and the Kingdom of Italy, as well as neighbouring Portugal, while the Soviet Union and Mexico intervened in support of the Republican government or loyalist side.

A civil war is a war between organized groups within the same nation state or republic, or, less commonly, between two countries created from a formerly united nation state. The aim of one side may be to take control of the country or a region, to achieve independence for a region, or to change government policies. The term is a calque of the Latin bellum civile which was used to refer to the various civil wars of the Roman Republic in the 1st century BC.

A civil war is a high-intensity conflict, often involving regular armed forces, that is sustained, organized and large-scale. Civil wars may result in large numbers of casualties and the consumption of significant resources.

Civil wars since the end of World War II have lasted on average just over four years, a dramatic rise from the one-and-a-half year average of the 1900-1944 period. While the rate of emergence of new civil wars has been relatively steady since the mid-19th century, the increasing length of those wars resulted in increasing numbers of wars ongoing at any one time. For example, there were no more than five civil wars underway simultaneously in the first half of the 20th century, while over 20 concurrent civil wars were occurring at the end of the Cold War, before a significant decrease as conflicts strongly associated with the superpower rivalry came to an end. Since 1945, civil wars have resulted in the deaths of over 25 million people, as well as the forced displacement of millions more. Civil wars have further resulted in economic collapse; Burma (Myanmar), Uganda and Angola are examples of nations that were considered to have promising futures before being engulfed in civil wars.

Robert Capa (born Endre Ernő Friedmann; October 22, 1913 – May 25, 1954) was a Hungarian combat photographer and photojournalist who covered five different wars: the Spanish Civil War, the Second Sino-Japanese War, World War II across Europe, the 1948 Arab-Israeli War, and the First Indochina War. He documented the course of World War II in London, North Africa, Italy, the Battle of Normandy on Omaha Beach and the liberation of Paris. His action photographs, such as those taken during the 1944 Normandy invasion, portray the violence of war with unique impact. In 1947, Capa co-founded Magnum Photos with, among others, the French photographer Henri Cartier-Bresson. The organization was the first cooperative agency for worldwide freelance photographers.

Born Endre Friedmann to Dezső and Júlia Friedmann on October 22, 1913 in Budapest, Hungary. Deciding that there was little future under the regime in Hungary, he left home at 18.

Capa originally wanted to be a writer; however, he found work in photography in Berlin and grew to love the art. In 1933, he moved from Germany to France because of the rise of Nazism, but found it difficult to find work there as a freelance journalist. He adopted the name "Robert Capa" around this time - in fact "cápa" ("shark") was his nickname in school and also he felt that it would be recognizable and American-sounding since it was similar to that of film director Frank Capra. He found it easier to sell his photos under the newly adopted "American" sounding name and over a period of time gradually assumed the persona of Robert Capa (with the help of his current girlfriend Gerda Taro, who acted as a intermediary between himself and those who purchased the photos taken by the "great American photographer, Robert Capa"). Capa's first published photograph was that of Leon Trotsky making a speech in Copenhagen on "The Meaning of the Russian Revolution" in 1932.

Eric Arthur Blair (25 June 1903 – 21 January 1950), better known by his pen name George Orwell, was an English novelist and journalist. His work is marked by keen intelligence and wit, a profound awareness of social injustice, an intense opposition to totalitarianism, a passion for clarity in language and a belief in democratic socialism.

Considered perhaps the 20th century's best chronicler of English culture, Orwell wrote literary criticism, poetry, fiction and polemical journalism. He is best known for the dystopian novel Nineteen Eighty-Four (1949) and the allegorical novella Animal Farm (1945), which together have sold more copies than any two books by any other 20th-century author. His book Homage to Catalonia (1938), an account of his experiences in the Spanish Civil War, is widely acclaimed, as are his numerous essays on politics, literature, language and culture. In 2008, The Times ranked him second on a list of "The 50 greatest British writers since 1945".

Orwell's influence on popular and political culture endures, and several of his neologisms, along with the term Orwellian—a byword for totalitarian or manipulative social practices—have entered the vernacular.
