Representative democracy Representative democracy is a variety of democracy founded on the principle of elected officials representing a group of people, as opposed to direct democracy. All modern Western style democracies are various types of representative democracies, for example the United Kingdom is a constitutional monarchy and Poland is a parliamentary republic.
