Direct democracy, classically termed pure democracy, comprises a form of democracy and theory of civics wherein sovereignty is lodged in the assembly of all citizens who choose to participate. Depending on the particular system, this assembly might pass executive motions (decrees), make law, elect and dismiss officials and conduct trials. Where the assembly elected officials, these were executive agents or direct representatives (bound to the will of the people). In a representative democracy sovereignty is exercised by a subset of the people, elected periodically, but otherwise free to advance their own agendas.
