A system or form of government that opposes or actively works against democratic principles and popular participation in decision-making.
From anti- + democracy. Democracy derives from Greek 'demos' (people) + 'kratos' (rule). This term emerged in political science to describe opposition ideologies.
An antidemocracy might be a monarchy, dictatorship, or oligarchy where power stays concentrated in a few hands instead of spreading across the population—basically the opposite of government 'of, by, and for the people!'
