Jewish volunteers in the Spanish Civil War

Jewish volunteers in the Spanish Civil War refers to Jews who joined International Brigades and fought in the Spanish Civil War, which erupted on July 17, 1936, and ended on April 1, 1939.

The fighting was between the Republicans, who were loyal to the Spanish Republic, and the Nationalists, a rebel group led by General Francisco Franco. The Nationalists prevailed and Franco would rule Spain for the next 36 years. The coup was supported by military units in Morocco, Pamplona, Burgos, Valladolid, Cádiz, Cordova, and Seville. However, barracks in important cities such as Madrid, Barcelona, Valencia, Bilbao and Málaga did not join in the rebellion. Spain was thus left militarily and politically divided. The rebels, led by General Franco, then embarked upon an almost three-year war against the government for the control of the country. The rebel forces received support from the Third Reich, the Kingdom of Italy, and neighboring Portugal, while the Soviet Union and Mexico intervened in support of the Republican side. Other countries, such as the United Kingdom and France, operated an official policy of non-intervention.

A minority of the Jewish population, particularly that of Europe, were active in socialist and Communist organisations in the period between the two World Wars.^{[1][page needed]}

They made up a considerable portion of the socialist volunteers, with estimates putting the figure at over ten per cent.^[2] Many of them joined the International Brigades and the Popular Front to fight in the Spanish Civil War on the side of the Republicans. The leadership of the International Brigades considered forming an entirely Jewish brigade,^[3] but the high casualties made this impossible. However, a Jewish company, the Naftali Botwin Company, was formed within the Palafox Battalion.

At least one Jewish volunteer is known to have served with the Nationalists. Emanual Rudolph Vischer was a former Oberleutnant of the Swiss Army who had lived in Spain prior to the Civil War. The official journal of the Swiss Armed Forces reported his death in September 1936.^[4]
