In the dictionary definition, democracy "is government by the people in which the supreme power is vested in the people and exercised directly by them or by their elected agents under a free electoral system." In the phrase of Abraham Lincoln, democracy is a government "of the people, by the people, and for the people."

 Freedom and democracy are often used interchangeably, but the two are not synonymous. Democracy is indeed a set of ideas and principles about freedom, but it also consists of a set of practices and procedures that have been molded through a long, often tortuous history. In short, democracy is the institutionalization of freedom. For this reason, it is possible to identify the time-tested fundamentals of constitutional government, human rights, and equality before the law that any society must possess to be properly called democratic.

 Democracies fall into two basic categories, direct and representative. In a direct democracy, all citizens, without the intermediary of elected or appointed officials, can participate in making public decisions. Such a system is clearly only practical with relatively small numbers of people--in a community organization or tribal council, for example, or the local unit of a labor union, where members can meet in a single room to discuss issues and arrive at decisions by consensus or majority vote. Ancient Athens, the world's first democracy, managed to practice direct democracy with an assembly that may have numbered as many as 5,000 to 6,000 persons--perhaps the maximum number that can physically gather in one place and practice direct democracy.
