Messalina Valeria
Messalina Valeria (born before ad 20ādied 48) was the third wife of the Roman emperor Claudius, notorious for licentious behaviour and instigating murderous court intrigues. The great-granddaughter of Augustusās sister, Octavia, on both her fatherās and motherās sides, she was married to Claudius before he became emperor. They had two children, Octavia (later Neroās wife) and Britannicus. Early sources maintain that Messalina allied herself with Claudiusās freedmen secretaries to dominate the emperor and to gratify her avarice and lust. In 42, Messalina caused Claudius to condemn to death a senator, Appius Silanus, who had slighted her advances. This heightened the tension between the emperor and Senate and prepared the way for a reign of terror in which many senators were executed after they had been denounced by Messalina. When she caused the death of Claudiusās freedman secretary, Polybius, however, the other freedmen turned against her. The correspondence secretary, Narcissus, managed to have her put to death by convincing Claudius that she and her lover, the consul designate Gaius Silius, had gone through a public wedding ceremony and were plotting to seize power.
