 A third and final area of research involves the relationship between representation and democracy. Historically, representation was considered to be in opposition with democracy [See Dahl (1989) for a historical overview of the concept of representation]. When compared to the direct forms of democracy found in the ancient city-states, notably Athens, representative institutions appear to be poor substitutes for the ways that citizens actively ruled themselves. Barber (1984) has famously argued that representative institutions were opposed to strong democracy. In contrast, almost everyone now agrees that democratic political institutions are representative ones.
