Red Napoleon was a nickname for a number of communist generals. The term was popularized in the 1920s by speculation among White Russian émigrés that one of the Soviet Union's top generals might overthrow the government in a coup. The term gained further currency in Western media as some observers worried that after such a coup, the "Red Napoleon" would lead an invasion of the rest of Europe. In later decades, it continued to be used occasionally to describe particularly capable communist generals, such as Mikhail Tukhachevsky and Võ Nguyên Giáp.
