Pablo Picasso painted Guernica,depicting the Nazi German bombing of Guernica, Spain, by twenty-eight bombers, on April 26, 1937 during the Spanish Civil War. The attack killed between 250 and 1,600 people, and many more were injured.
While living in Nazi-occupied Paris during World War II, Picasso suffered harassment from the Gestapo. One officer allegedly asked him, upon seeing a photo of Guernica in his apartment:
"Did you do that?"
"No, you did."
