Democracy is a system of governance where people rule through elected representatives. There are different types of democracies like presidential and parliamentary systems. Not all democracies provide the same levels of civil liberties and rule of law. There are degrees of democracy, with some countries having more authoritarian practices. Other regime types include authoritarian, totalitarian, and sultanic governments. Multiple factors can support or hinder democracy such as a country's political culture, history, and economic development. Transitions to democracy involve a process of liberalization and consolidation over time.
