Page "Agrippina the Younger" Paragraph 36

On the day that Agrippina married her uncle Claudius as her third husband / his fourth wife, she became an Empress and the most powerful woman in the Roman Empire.

She also was a stepmother to Claudia Antonia, Claudius ' daughter and only child from his second marriage to Aelia Paetina, and to the young Claudia Octavia and Britannicus, Claudius ' children with Valeria Messalina.

Agrippina removed or eliminated anyone from the palace or the imperial court who she thought was loyal and dedicated to the memory of the late Messalina.

She also eliminated or removed anyone who she considered was a potential threat to her position and the future of her son, one of her victims being Lucius ' second paternal aunt and Messalina's mother Domitia Lepida the Younger.
