Fanon goes into great detail explaining that revolutionary groups should look to the lumpenproletariat for the force needed to expel colonists. The lumpenproletariat in traditional Marxist theories are considered the lowest, most degraded stratum of the proletariat, especially criminals, vagrants, and the unemployed, who lacked class consciousness. Fanon uses the term to refer to those inhabitants of colonized countries who are not involved in industrial production, particularly peasants living outside the cities. He argues that only this group, unlike the industrial proletariat, has sufficient independence from the colonists to successfully make a revolution against them.
