Give me a brief summary of the spanish civil war

Context:
The Spanish Civil War broke out in 1936: on 17 and 18 July, part of the military carried out a coup d'état that triumphed in only part of the country. The situation led to a civil war, in which the territory was divided into two zones: one under the authority of the Republican government, that counted on outside support from the Soviet Union and Mexico (and from International Brigades), and the other controlled by the putschists (the Nationalist or rebel faction), most critically supported by Nazi Germany and Fascist Italy. The Republic was not supported by the Western powers due to the British-led policy of non-intervention. General Francisco Franco was sworn in as the supreme leader of the rebels on 1 October 1936. An uneasy relationship between the Republican government and the grassroots anarchists who had initiated a partial Social revolution also ensued.

The civil war was viciously fought and there were many atrocities committed by all sides. The war claimed the lives of over 500,000 people and caused the flight of up to a half-million citizens from the country. On 1 April 1939, five months before the beginning of World War II, the rebel side led by Franco emerged victorious, imposing a dictatorship over the whole country. Thousands of men and women were imprisoned after the civil war in Francoist concentration camps, with approximately 367,000 to 500,000 prisoners being held in 50 camps or prisons.<|im_end|>
