Lucius Cornelius Sulla the Roman dictator was the one responsible for the dramatic changer in Roman consitution. Sulla's politics was rather conservative, and Sulla had an objective to strengthen the Roman Senate and reduce the power of the plebeian tribunes. He retired in 79BC.
The act was about ensuring people have voting rights and preventing states from preventing voting rights in various ways such as having literacy tests or voting taxes or anything similar. One effect can be that it enabled for all people to vote regardless of color or origin, and another is that it enabled minorities and immigrants to vote too because it enabled minorities who didn't know English that well to vote using bilingual ballots.
