The concept of universal suffrage gives the right to vote to all adult citizens, regardless of wealth, income, gender, social status, ethnicity, political stance, or any other restriction, subject to only relatively minor exceptions.
The attainment of universal suffrage over various forms of voting restrictions has been one of the major accomplishments in the development of modern democratic institutions. Struggles for the vote have had to overcome restrictions based on factors such as sex, race, and tenure of property.
