Spanish Civil War in the context of "Class struggle"

World War II or the Second World War (1 September 1939 – 2 September 1945) was a global conflict between two coalitions: the Allies and the Axis powers. Nearly all of the world's countries participated, with many nations mobilising all resources in pursuit of total war. Tanks and aircraft played major roles, enabling the strategic bombing of cities and delivery of the first and only nuclear weapons ever used in war. World War II is the deadliest conflict in history, causing the death of 70 to 85 million people, more than half of whom were civilians. Millions died in genocides, including the Holocaust, and by massacres, starvation, and disease. After the Allied victory, Germany, Austria, Japan, and Korea were occupied, and German and Japanese leaders were put on trial for war crimes.

The causes of World War II included unresolved tensions in the aftermath of World War I, the rise of fascism in Europe and militarism in Japan. Key events preceding the war included Japan's invasion of Manchuria in 1931, the Spanish Civil War, the outbreak of the Second Sino-Japanese War in 1937, and Germany's annexations of Austria and the Sudetenland. World War II is generally considered to have begun on 1 September 1939, when Nazi Germany, under Adolf Hitler, invaded Poland, after which the United Kingdom and France declared war on Germany. Poland was divided between Germany and the Soviet Union under the Molotov–Ribbentrop Pact. In 1940, the Soviet Union annexed the Baltic states and parts of Finland and Romania. After the fall of France in June 1940, the war continued mainly between Germany, now assisted by Fascist Italy, and the British Empire, with fighting in the Balkans, Mediterranean, and Middle East, the aerial Battle of Britain and the Blitz, and the naval Battle of the Atlantic. Through campaigns and treaties, Germany gained control of much of continental Europe and formed the Axis alliance with Italy, Japan, and other countries. In June 1941, Germany invaded the Soviet Union, opening the Eastern Front and initially making large territorial gains.

Anarchism is a political philosophy and movement that seeks to abolish all institutions that perpetuate authority, coercion, or hierarchy, primarily targeting the state and capitalism. Anarchism advocates for the replacement of the state with stateless societies and voluntary free associations. A historically left-wing movement, anarchism is usually described as the libertarian wing of the socialist movement (libertarian socialism).

Although traces of anarchist ideas are found all throughout history, modern anarchism emerged from the Enlightenment. During the latter half of the 19th and the first decades of the 20th century, the anarchist movement flourished in most parts of the world and had a significant role in workers' struggles for emancipation. Various anarchist schools of thought formed during this period. Anarchists have taken part in several revolutions, most notably in the Paris Commune, the Russian Civil War and the Spanish Civil War, whose conclusion marked the end of the classical era of anarchism. In the last decades of the 20th and into the 21st century, the anarchist movement has been resurgent once more, growing in popularity and influence within anti-capitalist, anti-war and anti-globalisation movements.

The causes of World War II have been given considerable attention by historians. The immediate precipitating event was the invasion of Poland by Nazi Germany on September 1, 1939, and the subsequent declarations of war on Germany made by Britain and France, but many other prior events have been suggested as ultimate causes. Primary themes in historical analysis of the war's origins include the political takeover of Germany in 1933 by Adolf Hitler and the Nazi Party; Japanese militarism against China, which led to the Japanese invasion of Manchuria and the Second Sino-Japanese War; Italian aggression against Ethiopia, which led to the Second Italo-Ethiopian War; or military uprising in Spain, which led to the Spanish Civil War.

During the interwar period, deep anger arose in the Weimar Republic over the conditions of the 1919 Treaty of Versailles, which punished Germany for its role in World War I with heavy financial reparations and severe limitations on its military that were intended to prevent it from becoming a military power again. The demilitarisation of the Rhineland, the prohibition of German unification with Austria, and the loss of its overseas colonies as well as some 12% of the pre-war land area and population of the metropole all provoked strong currents of revanchism in German politics.

A civil war is a war between organized groups within the same state (or country). 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 Latin bellum civile which was used to refer to the various civil wars of the Roman Republic in the 1st century BC. Civil here means "of/related to citizens", a civil war being a war between the citizenry, rather than with an outsider.

Most modern civil wars involve intervention by outside powers. According to Patrick M. Regan in his book Civil Wars and Foreign Powers (2000) about two thirds of the 138 intrastate conflicts between the end of World War II and 2000 saw international intervention.

Pablo Ruiz Picasso (25 October 1881 – 8 April 1973) was a Spanish painter, sculptor, printmaker, ceramicist, and theatre designer who spent most of his adult life in France. One of the most influential artists of the 20th century, he is known for co-founding the Cubist movement, the invention of constructed sculpture, the co-invention of collage, and for the wide variety of styles that he helped develop and explore. Among his most famous works are the proto-Cubist Les Demoiselles d'Avignon (1907) and the anti-war painting Guernica (1937), a dramatic portrayal of the bombing of Guernica by German and Italian air forces during the Spanish Civil War.

Beginning his formal training under his father José Ruiz y Blasco aged seven, Picasso demonstrated extraordinary artistic talent from a young age, painting in a naturalistic manner through his childhood and adolescence. During the first decade of the 20th century, his style changed as he experimented with different theories, techniques, and ideas. After 1906, the Fauvist work of the older artist Henri Matisse motivated Picasso to explore more radical styles, beginning a fruitful rivalry between the two artists, who subsequently were often paired by critics as the leaders of modern art.

Spain first participated at the Olympic Games in 1900, and has sent athletes to compete in most Summer Olympic Games since 1920. Spain has also participated in every Winter Olympic Games since 1936. Its team is organised by the Spanish Olympic Committee (COE, Comité Olímpico Español) created in 1924.

Spain withdrew from the 1936 Summer Olympics in Nazi Germany because of the Civil War, and also boycotted the 1956 Games in Melbourne because of the Soviet Union's invasion of Hungary. The equestrian events in 1956 were held five months earlier in Stockholm, and Spain did participate in those events.

Anarcho-syndicalism is an anarchist organisational model that centres trade unions as a vehicle for class conflict. Drawing from the theory of libertarian socialism and the practice of syndicalism, anarcho-syndicalism sees trade unions as both a means to achieve immediate improvements to working conditions and to build towards a social revolution in the form of a general strike, with the ultimate aim of abolishing the state and capitalism. Anarcho-syndicalists consider trade unions to be the prefiguration of a post-capitalist society and seek to use them in order to establish workers' control of production and distribution. An anti-political ideology, anarcho-syndicalism rejects political parties and participation in parliamentary politics, considering them to be a corrupting influence on the labour movement. In order to achieve their material and economic goals, anarcho-syndicalists instead practice direct action in the form of strike actions, boycotts and sabotage. Anarcho-syndicalists also attempt to build solidarity among the working class, in order to unite workers against the exploitation of labour and build workers' self-management.

The foundations of anarcho-syndicalism were laid by the anti-authoritarian faction of the International Workingmen's Association (IWMA) and developed by the French General Confederation of Labour (CGT). Anarcho-syndicalism was constituted as a specific tendency following the International Anarchist Congress of Amsterdam in 1907, which led to anarcho-syndicalism becoming the dominant form of trade union organisation in Europe and Latin America. After facing suppression during the Revolutions of 1917–1923, anarcho-syndicalists established the International Workers' Association (IWA) in 1922. Anarcho-syndicalism reached its apex during the Spanish Revolution of 1936, when the National Confederation of Labour (CNT) established an anarcho-syndicalist economy throughout much of the Spanish Republic. Anarcho-syndicalism went into decline after the defeat of the anarchists in the Spanish Civil War in 1939. The movement split into two factions: the "orthodox" faction, which held to traditional syndicalist principles in spite of changing material conditions; and the "revisionist" faction, which aimed to achieve a mass base and work within the framework of newly established welfare states. By the end of the 20th century, the rise of neoliberalism and the collapse of the Eastern Bloc had led to a revival in anarcho-syndicalism, with syndicalist unions once again being established throughout the globe.
