Antonia Minor
With Augustus being the father of only one daughter (Julia by Scribonia), Livia revealed herself to be an ambitious mother and soon started to push her own sons Tiberius and Drusus into power. Drusus was a trusted general and married Augustus' favorite niece, Antonia Minor, having three children: the popular general Germanicus, Livilla, and the future emperor Claudius. Tiberius married Augustus' daughter Julia in 11 BC and was ultimately adopted as Augustus' heir in AD 4.
