Which citizens rule themselves by majority vote?

Citizens who rule themselves by majority vote typically belong to democratic systems, where decisions are made through elections and referendums. In direct democracies, such as those seen in ancient Athens or modern-day Switzerland, citizens participate directly in decision-making. In representative democracies, citizens elect representatives who then make decisions on their behalf, often guided by majority rule principles. Ultimately, the concept of majority rule is a foundational element of democratic governance.
