Robert Dahl

Robert Alan Dahl (; December 17, 1915 – February 5, 2014) was an American political theorist and Sterling Professor of Political Science at Yale University. He established the pluralist theory of democracy—in which political outcomes are enacted through competitive, if unequal, interest groups—and introduced "polyarchy" as a descriptor of actual democratic governance. An originator of "empirical theory" and known for advancing behavioralist characterizations of political power, Dahl's research focused on the nature of decision making in actual institutions, such as American cities. He is the most important scholar associated with the pluralist approach to describing and understanding both city and national power structures. In addition to his work on the descriptive theory of democracy, he was long occupied with the formulation of the constituent elements of democracy considered as a theoretical but realizable ideal. He has been credited to be a major theorist of democracy, with supporters praising what they claim to be the cogency, clarity and veracity of his portrayal of some of the key characteristics of ‘realizable-ideal’ democracy, as well as his descriptive analysis of the dynamics of modern pluralist-democracy.
