Guernica was the first city ever to be bombed by air. The bombing which took place in 1937 was a Nazi experiment. This was condoned by Franco during the Spanish Civil War so he could overthrow the Spanish government in a coup to join forces with the Germans and Italians. Picasso was scheduled to represent Spain at the Universal Exhibition of 1937 in Paris. He created this work to denounce this atrocity. Painted in two months, the artist made 45 preparatory sketches for Guernica. It measures 3.5x8 meters.
