List of Augustae

Augusta (Classical Latin:; plural Augustae; Greek: αὐγούστα) was a Roman imperialhonorific title given to empresses and women of the imperial families. It was the feminine form of Augustus.

In the second and third centuries, Augustae could also receive the title of Mater Castrorum ("Mother of the Camp") or Mater Castrorum et Senatus et Patriae ("Mother of the Camp, Senate and Fatherland").

The title implied the greatest prestige. Augustae could issue their own coinage, wear imperial regalia, and rule their own courts.

Agrippina, the wife of Claudius, was the first living wife of the emperor in Roman history to receive the title of Augusta, a position she held for the rest of her life, ruling with her husband and son.

In the third century, Julia Domna was the first empress to receive the combined title Pia Felix Augusta after the death of her husband Septimius Severus, which may have implied greater powers being vested in her than was usual for a Roman empress mother. In this official position and honor, she accompanied her son on an extensive military campaign and provincial tour.
