Which democratic process used in the United States is most similar to that of ancient Greece?

The most similar democratic process used in the United States to that of ancient Greece is direct democracy, characterized by citizens participating directly in decision-making rather than through elected representatives. In ancient Greece, particularly in Athens, citizens participated in assemblies where they could vote directly on legislation and policy matters, reflecting the principle of direct democracy.

In modern contexts, while the United States primarily operates as a representative democracy, elements of direct democracy still exist, such as in certain state-level initiatives and referenda where citizens vote directly on specific issues. However, the most precise comparison to ancient Greek practices lies in direct democracy, which allows for a more active engagement of the populace in the legislative process.

While referendums, elections, and judicial review are important aspects of the democratic system in the U.S., they do not embody the same level of direct public involvement in governance that is characteristic of ancient Greek democracy. Therefore, direct democracy is the most fitting similarity to the democratic processes of that era.
