What describes a system in which citizens have direct participation in government decisions?

The concept of direct democracy is characterized by citizens directly participating in decision-making processes rather than relying on elected representatives. In a direct democracy, individuals have the power to vote on laws and policies themselves, thus ensuring that their voices are heard in governance. This system emphasizes the involvement of the populace in shaping their own government and policies, making it distinct from representative forms or systems where elected officials make decisions on behalf of the citizens.

In contrast, autocracy is a system where a single ruler holds all power, which limits citizen involvement. Oligarchy is characterized by a small group of elites making decisions, excluding the general population from direct participation. Representative democracy, while allowing citizens to elect representatives to make decisions on their behalf, does not grant individuals the same level of direct influence over policy as found in direct democracy.
