In his history of the Spanish Civil War , Antony Beevor " reckons Franco 's ensuing ' white terror ' claimed 200,000 lives . The ' red terror ' had already killed 38,000 . " Julius Ruiz concludes that " although the figures remain disputed , a minimum of 37,843 executions were carried out in the Republican zone with a maximum of 150,000 executions ( including 50,000 after the war ) in Nationalist Spain . " Despite the official end of the war , guerrilla resistance to Franco ( known as " the '' maquis '' " ) was widespread in many mountainous regions , and continued well into the 1950s . In 1944 , a group of republican veterans , which also fought in the French resistance against the Nazis , invaded the Val d'Aran in northwest Catalonia , but they were quickly defeated
