Conflict theory focuses on political, social and material inequality between social groups. Feminist theory is an example of contemporary conflict theory. Feminist theory views the condition of women as arising out of a social, political and economic imbalance between men and women; hence, the struggle of women for equality.
Marxism is the origin of modern conflict theory. Marx saw history as a process of conflict between segments or classes of society with unequal power. Because of this imbalance of power, the different classes developed different interests under a capitalist system.
Feminist theory, on the other hand, is a conflict theory that focuses on gender inequality as distinct from issues of economic class.
