Switzerland is unique among modern nations for its extensive use of direct democracy. At the cantonal and federal levels, citizens frequently participate in referendums and popular initiatives to vote directly on legislation and constitutional amendments. This system allows the Swiss electorate to have a significant and direct influence on the law-making process, distinguishing it from the purely representative systems found in most other modern democratic states.
