In Spain during the Spanish Civil War, the Basque town of Guernica is bombed by the German Luftwaffe, resulting in widespread destruction and casualties. The Basque government reports 1,654 people killed, while later research suggests far fewer deaths, but regardless, Guernica is viewed as an example of terror bombing and other countries learn that Nazi Germany is committed to that tactic. The bombing also becomes inspiration for Pablo Picasso, resulting in a protest painting that is not only his most famous work, but one the most important pieces of art ever produced.
