Picasso's famous painting Guernica from 1937 depicts the suffering of people during the bombing of Guernica by German and Italian warplanes at the behest of the Spanish Nationalists during the Spanish Civil War. The large black-and-white canvas portrays different forms of human suffering including dismembered bodies, screaming faces of men, women and children, and dead or dying animals amid the destruction. The painting brought international attention to the tragedy of the bombing and became a universal symbol of the atrocities of war.
