Social chauvinism

Social chauvinism can be described as aggressive or fanatical patriotism, particularly during time of war, in support of one's own nation (e.g., government, culture, etc.) versus other nation(s), displayed by those who are socialists or social democrats. During World War I, most left-wing political parties took a social-chauvinist stand, with few exceptions. Most Socialists gave up their anti-militarism and their belief in international unity among the working class in favour of "defense of the fatherland", and turned to social-chauvinism, most notably the German Social Democratic Party and the French Socialist Party.
