Expansionist nationalism is an aggressive and radical form of nationalism that incorporates autonomous, patriotic sentiments with a belief in expansionism. The term was coined during the late nineteenth century as European powers indulged in the 'Scramble for Africa' in the name of national glory, but has been most associated with militarist governments during the 20th century including Fascist Italy, Nazi Germany, the Japanese empire, and post-Yugoslav Serbia.
Ideology
What distinguishes expansionist nationalism from liberal nationalism is its acceptance of chauvinism, a belief in superiority or dominance. Nations are thus not thought to be equal to their right to self-determination; rather some nations are believed to possess characteristics or qualities that make them superior to others. Expansionist nationalism therefore asserts the state's right to increase its borders at the expense of its neighbours.
