Livia Drusilla
Roman Senator Marcus Livius Drusus Claudianus and Alfidia were the parents of Livia Drusilla, one of the most powerful ladies in ancient Rome. Emperor Augustus was married to Livia Drusilla for 51 years. Livia was by all accounts the obediently modest and diligent woman that the Romans expected her to be. She nevertheless put quite a lot of effort in the background, coaching Augustus, to keep the Imperial System working.
She served as one of Emperor Augustus' top advisors and oversaw the government long after his demise and under the rule of Tiberius, her son by Nero. She was renowned for acting in the background while her husband and son served as powerful leaders, acting as their confidantes and counselor.
In his testament, Emperor Augustus gave Livia a portion of his estate and adopted her into the Julian dynasty, giving her the new namesake and title of Julia Augusta.
After her death in 29 AD, she was revered as the Divine Augusta. She was, however, blamed for killing her husband, Augustus, while he was still alive.
