Octavia

Octavia sister of Octavian who went on to become the first emperor of Rome.

As part of a political alliance between Octavian and Mark Antony, she became Antony's wife. His open abandonment of her when he went to live in Egypt with Cleopatra and 'married' her, led to an ever growing rift between Octavian and Antony that led to war and eventually to Octavian becoming the first Roman Emperor as Augustus. Octavia had a daughter with Antony, Antonia, who was the mother of Claudius, the fourth Emperor of Rome.
