During the 1930s radical leftist politics characterized many of the artists connected to Surrealism, including Pablo Picasso. On 26 April 1937, during the Spanish Civil War, the Basque town of Gernika was bombed by Nazi Germany's Luftwaffe. The Germans were attacking to support the efforts of Francisco Franco to overthrow the Basque government and the Spanish Republican government. Pablo Picasso painted his mural-sized "Guernica" to commemorate the horrors of the bombing.
