The famous female assassin associated with the assassination of Julius Caesar's heir, Brutus, is Servilia of Cadiz. While historical records primarily focus on the prominent male figures involved in Caesar's assassination, Servilia is often noted for her influence. She was not only Brutus's mother but also had a romantic relationship with Caesar, drawing connections that intertwine her personal life with significant political events. However, her direct involvement in the assassination plot is more figurative than literal.
