Big man (political science)
The terms big man, big man syndrome, and bigmanism, within the context of political science, refer to a single person's rule over a country, often in a corrupt, autocratic and to some extent totalitarian manner. Generally associated with neopatrimonial states, where there is a framework of formal law and administration but the state is informally captured by patronage networks.
