World War I introduced the world to killing and destruction on a scale never seen before. During the battle of the Somme, 19,000 men died on the first day alone. By the end of the campaign the British had gained only 125 miles of territory at a terrible cost: casualties on both sides exceeded one million. For many, the senseless slaughter represented the worst expression of European imperialism, militarism, and nationalism. A 1914 cartoon published in the Chicago Daily News uses racial chauvinism to condemn the European war for undermining the moral supremacy of "Western Civilization."
