Universal suffrage is the right of all adult citizens to vote in elections, regardless of their race, gender, or social status. This principle ensures that every individual has an equal voice in the democratic process, allowing them to participate in choosing their representatives and influencing government policies. Historically, many groups were denied the right to vote, leading to movements advocating for women's suffrage and the rights of racial minorities. Achieving universal suffrage has been a significant milestone in promoting equality and democracy in societies around the world.
