The political concept that describes a system in which citizens participate directly in decision-making is known as direct democracy. In this system, citizens engage actively in voting and deliberation on policy issues, rather than solely electing representatives to make decisions on their behalf. While full direct democracy is rare in modern governments, elements can be seen in practices like referendums and town hall meetings. This concept empowers citizens to have a voice in governance, fostering accountability and enhancing civic engagement in the democratic process.
