Aggressive or fanatical patriotism, particularly during time of war, in support of one's own nation or other nation(s). During WWI, nearly every political party took a social-chauvinist stand; with few exceptions. Most Socialists gave up their beliefs in favour of "defense of the fatherland," and turned to social-chauvinism; most notably the German Social Democratic Party. Two outstanding examples of Communists who fought against social-chauvinism during WWI were Rosa Luxemburg and Karl Liebknecht. They stressed that the only violence that should be used is the violence necessary to overthrow one's own government. They agitated tirelessly in their nation to show that common social relations united workers across any national boundaries and that the only blood the proletariat should shed is the blood to gain their freedom.
