In political science, minoritarianism is a neologism for a political structure or process in which a minority group of a population has a certain degree of primacy in that population's decision making, with legislative power or judicial power being held or controlled by a minority group rather than a majority that is representative of the population. Minoritarianism is sometimes used to describe minority rule, rule by a dominant minority such as an ethnic group delineated by religion, language, or some other identifying factor.
