 Nationalism was seen as a tool that the bourgeoisie used to divide and rule the proletariat (bourgeois nationalism).Whereas the influence of international communism was very strong from the late 19th century through the 1920s, the decades after that—beginning with socialism in one country and progressing into the Cold War and the Non-Aligned Movement—made national communism a larger political reality.During the decade of the 1840s, the word "communist" came into general use to describe those who hailed the left-wing of the Jacobin Club of the French Revolution as their ideological forefathers.
