Abstract
Revolution, which embodies major turns in the course of history, has for a long time been a social study subject. With the coming of the school of public choice in the 1960's, a new economic current helped to undestand revolution. Many economists such as: James M. Buchanan (1962), Gordon Tullock (1971-1974) and John E. Romer (1985) have applied economic theory to social and political science using tools developed by microeconomy. The goal of my research paper is to highlight the contribution of economic theory in the understanding of revolution. I have first drawn a line between two approaches that have studied revolution: The sociological approach which mainly explains why do people revolt when they are faced with structural imbalances. The economic approach which uses the theory of rational choice to demonstrate how people choose to be passive when they are confronted with a revolution.
