Клавдия Марцелла
On September 2, 31 BC, the Battle of Actium was fought. Octavian's victory, which gave him the mastery of Rome and the empire, was mainly due to Agrippa. Octavian then bestowed upon him the hand of his niece Claudia Marcella Major in 28 BC. He also served a second consulship with Octavian the same year. In 27 BC, Agrippa held a third consulship with Octavian, and in that year, the senate also bestowed upon Octavian the imperial title of Augustus.
