Democracy is a form of government. The origin of the term is Greek, from the words demos (people) and kratos (rule). Although many forms of government fall under this broad classification, the defining characteristic of a democracy is that the citizenry of a nation decides upon their form of government.
The United States of American is an example of a representative democracy, in which the populace elects representatives, who are charged with the protection of liberties.
Although a number of societies have practiced some form of democracy, the concept as it is understood today was invented in ancient Athens, where citizens (not women or slaves) were allowed to vote in the Assembly which made the laws of the city-state.
