Democracy is a form of government in which all eligible citizens have an equal say in the decisions that affect their lives. Democracy allows eligible citizens to participate equally—either directly or through elected representatives—in the proposal, development, and creation of laws. It encompasses social, economic and cultural conditions that enable the free and equal practice of political self-determination.
The term originates from the Greek δημοκρατία (dēmokratía) "rule of the people", which was coined from δῆμος (dêmos) "people" and κράτος (kratos) "power" or "rule" in the 5th century BCE to denote the political systems then existing in Greek city-states, notably Athens; the term is an antonym to ἀριστοκρατία(aristocratie) "rule of an elite." While theoretically these definitions are in opposition, in practice the distinction has been blurred historically. The political system of Classical Athens, for example, granted democratic citizenship to an elite class of free men and excluded slaves and women from political participation. In virtually all democratic governments throughout ancient and modern history, democratic citizenship consisted of an elite class until full enfranchisement was won for all adult citizens in most modern democracies through the suffrage movements of the 19th and 20th centuries. The English word dates to the 16th century, from the older Middle French and Middle Latin equivalents.
A democratic government contrasts to forms of government where power is either held by one, as in a monarchy, or where power is held by a small number of individuals, as in an oligarchy. Nevertheless, these oppositions, inherited from Greek philosophy, are now ambiguous because contemporary governments have mixed democratic, oligarchic, and monarchic elements. Karl Popper defined democracy in contrast to dictatorship or tyranny, thus focusing on opportunities for the people to control their leaders and to oust them without the need for a revolution.
