A democracy is a type of government where the creation, evolution and proposal of laws are made through the engagement of all eligible citizens. There are several types of democratic systems, such as direct and semi-direct, representative, parliamentary, presidential, constitutional and hybrid democracies.
A democracy has four major pillars consisting of a law, the safeguard of human rights, participation of the citizens and fair elections to choose and replace the body of government.
In a direct democracy, all eligible citizens directly participate in the political system by changing constitutional laws, suggesting or initiating laws and binding officials to their campaign promise by threat of dismissal or lawsuit.
A representative democracy elects officials through a free and fair vote of popularity to represent the citizens and their interests. In a parliamentary democracy, representatives of the citizens can appoint and dismiss members of government if they don't live up to their standards.
A presidential democracy is a type of government where a president is elected by the people in a free election and gains power over the state and government, effectively gaining the majority of executive powers.
A constitutional democracy binds elected representatives to a constitution constraining the powers of officials.
A hybrid democracy uses parts of representative and direct democracies to form participatory democracies. Examples include the U.S. states of California, Vermont, the New England region and the country of Switzerland. The first democracy was a direct democracy performed by the Greek people.
