Cornelia was the daughter of LuciusCornelius Cinna, one of the most influential politicians at Rome during the conflict between the generals Gaius Marius and Lucius Cornelius Sulla. He held the consulship for an unprecedented term of four consecutive years, from BC 87 to 84, when he was slain in a soldiers' mutiny. During this period, he espoused the side of Marius, leaving his family exposed to Sulla's wrath on the latter's return in 82. By his wife, Annia, Cinna had a son, Lucius, and two daughters, conventionally known as Cornelia Major, who married Gnaeus Domitius Ahenobarbus, and Cornelia Minor, the wife of Caesar. The designations Major and Minor were not really part of their names, but were used to distinguish between sisters, who bore the same nomen. Since there were a great many Corneliae at Rome, Caesar's wife is occasionally referred to as Cornelia Cinnae, or "Cinna's Cornelia".
Marriage
reports that Caesar and Cornelia were married in the consulate occurring after Caesar lost his father, which occurred in his sixteenth year. In Suetonius' chronology, Caesar was born in 100 BC, placing the death of his father in 85 or 84. Thus, he probably married Cornelia in 83, when he was about seventeen years old, and she perhaps a little younger. Their daughter, Julia, was Caesar's only legitimate child, and the only one he acknowledged. The young Caesar was one of those to whom Sulla turned his attention after returning to Rome. Although he had taken no part in the government of Marius and Cinna, and done nothing to oppose Sulla's return, Caesar's aunt, Julia, was the wife of Marius; his cousin was the younger Marius, who as consul in 82 was defeated by Sulla, and had taken his own life as the cityfell. Marius and Cinna had appointed the young Caesar to an important priesthood, and by marrying Cinna's daughter, Caesar gained control of a substantial dowry. Sulla regarded Caesar as a potential rival, and commanded him to divorce Cornelia. However, neither the deprivation of his priesthood, Cornelia's dowry, and his own inheritance, nor the threat of violence, would induce Caesar to forsake his wife. He was proscribed, and escaped Rome in disguise, evading capture by regularly changing his place of concealment, and on at least one occasion by bribing the commander of a patrol sent to search for Sulla's enemies. Eventually Sulla relented, following the intercession of Caesar's numerous friends and kinsmen, and Caesar returned home to Cornelia.
Death
After about thirteen years of marriage, Cornelia died early in her husband's quaestorship, which occurred in BC 69 or 68. Caesar was due to depart for Spain, and had already pronouncedthe funeral oration of his aunt, Julia, from the rostra, as was customary for elderly Roman matrons. He then gave an oration in honour of Cornelia, which was extraordinary in the case of a young woman, although it later became commonplace. Historically, Cornelia is often stated to have died in childbirth, but this is not confirmed.
