The Spanish Civil War (1936-1939) was a conflict along many ideological, ethnic and religious lines. It started as a military coup by the Nationalists against the Republic of Spain after which the country was severely divided. In general, the Nationalists were supported by conservatives, and the Republicans by a wide variety of social-democrats, communists and anarchists, but the divisions also took regional forms with for example Catalans and Basques opposing a centralist nationalist regime. The civil war caused a lot of international attention and both sides were supported by ideologically aligned states and volunteers. Spanish civil war coinage consists of both emergency coinage and coins that were aimed at symbolising regional autonomy or opposition to the nationalists.
