Cato, a Tragedy is a play written by Joseph Addison in 1712, and first performed on 14 April 1713. Based on the events of the last days of Marcus Porcius Cato Uticensis (better known as Cato the Younger) (95–46 B.C.), a Stoic whose deeds, rhetoric and resistance to the tyranny of Julius Caesar made him an icon of republicanism, virtue, and liberty. Addison's play deals with, among other things, such themes as individual liberty versus government tyranny, Republicanism versus Monarchism, logic versus emotion, and Cato's personal struggle to hold to his beliefs in the face of death. It has a prologue written by Alexander Pope, and an epilogue by Samuel Garth.
The play was a success throughout England and her possessions in the New World, as well as Ireland. It continued to grow in popularity, especially in the American colonies, for several generations. Indeed, it was almost certainly a literary inspiration for the American Revolution, being well known to many of the Founding Fathers. In fact, George Washington allegedly had it performed for the Continental Army while they were encamped at Valley Forge. The letter which proves the performance has questionable authenticity.
The action of the play involves the forces of Cato at Utica, awaiting the arrival of Caesar just after Caesar's victory at Thapsus (46 B.C.). The noble sons of Cato, Portius and Marcus, are in love with Lucia, the daughter of Lucius, a senatorial ally of Cato. Juba, prince of Numidia, another fighting on Cato's side, loves Cato's daughter Marcia. Meanwhile, Sempronius, another senator, and Syphax, general of the Numidians, are conspiring secretly against Cato, hoping to draw off the Numidian army from supporting him.
Some scholars, including historian David McCullough—author of 1776—believe that several famous quotations from the American Revolution came from, or were inspired by, Cato. These include:
