List of Augustae
Augusta was a Roman imperial honorific title given to empresses and honoured women of the imperial families. It was the feminine form of Augustus. In the third century, Augustae could also receive the titles of Mater Castrorum and Mater Patriae.
The title implied the greatest prestige. Augustae could issue their own coinage, wear imperial regalia, and rule their own courts.
In the third century, Julia Domna was the first empress to receive the title combination "Pia Felix Augusta" after the death of her husband Septimius Severus, which may have implied greater powers being vested in her than what was usual for a Roman empress mother.
