Seneca was born in Corduba (now Córdoba), Spain. His father, known as Seneca the Elder, was also called Lucius Annaeus Seneca and was a noted statesman and author. Educated in Rome, the younger Seneca studied rhetoric, philosophy, and law. As a young man he entered politics.
A political enemy, Messalina, induced Emperor Claudius to exile Seneca to Corsica in AD 41. Seneca spent eight years on this island, and during this period he wrote many of the works that made him famous. He was called back to Rome at the request of Agrippina, the wife of Claudius. Seneca served as tutor to her son, Domitius, the future Emperor Nero. When Nero became emperor in 54, he chose Seneca as one of his two main advisers. The other was Sextus Afranius Burrus, a renowned general.
Seneca's influence declined after Burrus' death in 62. After a conference with Nero, Seneca left Rome and retired to his villa. In 65, when Seneca was charged with involvement in a plot against the state, Nero ordered him to commit suicide. Seneca promptly obeyed, dying calmly in his home.
Most of Seneca's philosophical writings are essays on practical ethics, based on modified Stoicism (see Stoicism). He also wrote several books on astronomy and meteorology. His dramas were slavish and generally uninteresting imitations of the Greek tragedies. (Encyclopedia Britannica)
For almost a decade Lucius Annaeus Seneca was one of the most powerful men in the Roman Empire. An adviser to Emperor Nero, Seneca also wrote philosophical works and dramas.
