Cato the Younger was one of the many biographies documented by Plutarch in his series called Parallel Lives. Related to Cato the Elder, Cato the Younger was also a student of philosophy as well as a Roman Statesman. After his father died and he gained his inheritance, Cato the Younger began his life as philosopher, warrior, and political leader. His life ended, as so many Roman lives did back then, in tragedy.
