The list below includes Roman women who were notable for their family connections, or their sons or husbands, or their own actions. In the earlier periods, women came to the attention of (later) historians either as poisoners of their husbands (a very few cases), or as wives, daughters, and mothers of great men such as Scipio Africanus. In later periods, women exercised or tried to exercise political power either through their husbands (as did Fulvia and Livia Drusilla) or political intrigues (as did Clodia and Servilia), or directly (as did Agrippina the younger and later Roman empresses). Even the Severan dynasty from the beginning to the end was completely dominated by four powerful and calculating women.
