Marcus Porcius Cato Uticensis (95 BC, Rome – April 46 BC, Utica), commonly known as Cato the Younger (Cato Minor) to distinguish him from his great-grandfather (Cato the Elder), was a politician and statesman in the late Roman Republic, and a follower of the Stoic philosophy. A noted orator, he is remembered for his stubbornness and tenacity (especially in his lengthy conflict with Julius Caesar), as well as his immunity to bribes, his moral integrity, and his famous distaste for the ubiquitous corruption of the period.
Cato was born in 95 BC in Rome, the son of Marcus Porcius Cato and his wife, Livia. His parents died when he was young, and he was cared for by his maternal uncle, Marcus Livius Drusus, who also looked after Cato's sister, Porcia, a half-brother, Quintus Servilius Caepio, and two half-sisters, Servilia Major, and Servilia Minor. Cato was four when his uncle was assassinated in 91, an event which helped to spark the Social War.
Cato's stubbornness began in his early years. Sarpedon, his teacher, reports a very obedient and questioning child, although slow in being persuaded of things and sometimes very difficult to retrain. A story told by Plutarch tells of Quintus Poppaedius Silo, leader of the Marsi and involved in controversial business in the Roman Forum, who made a visit to his friend Marcus Livius and met the children of the house. In a playful mood, he asked the children's support for his cause. All of them nodded and smiled except Cato, who stared at the guest suspiciously. Silo demanded an answer from him and, seeing no response, took Cato and hung him by the feet out of the window. Even then, Cato would not say anything.
