Julia Domna ( c. 160 – 217 AD) was Roman empress from 193 to 211 as the wife of Emperor Septimius Severus. She was the first empress of the Severan dynasty. Domna was born in Emesa (present-day Homs) in Roman Syria to an Arab family of priests of the deity Elagabalus. In 187, she married Severus, then-governor of the Roman province of Gallia Lugdunensis. They had two sons, Caracalla and Geta. A civil war over the Roman throne broke out in 193, and shortly afterwards Severus declared himself Emperor. The war ended in 197 with the defeat of the last of Severus's opponents.
 
As empress, Domna was famous for her political, social, and philosophical influence. She received titles such as "Mother of the Invincible Camps". After the elder of her sons, Caracalla, started ruling with his father, she was briefly co-empress with Caracalla's wife, Fulvia Plautilla, until the latter fell into disgrace.  Following the death of Severus in 211, Domna became the first Empress Dowager to receive the title combination "Pia Felix Augusta", which may have implied greater powers being vested in her than what was usual for a Roman empress mother. Her sons jointly inherited the throne, and she acted as mediator in the conflicts that arose between them. Caracalla had Geta killed later that year.
 
In 217, Caracalla began a new war with Parthia. Domna went with Caracalla as far as Antioch. There she stayed, helping to deal with his correspondence, while he went on to the frontier. During the campaign, Caracalla was assassinated by a Roman soldier. Domna chose to commit suicide after hearing about the rebellion, perhaps a decision hastened by the fact that she was suffering from breast cancer, as well as a reluctance to return to private life. Her sister, Julia Maesa, restored the Severan dynasty in 218. Domna's body was brought to Rome and placed in the Sepulcrum C. et L. Caesaris (perhaps a separate chamber in the Mausoleum of Augustus). Later, however, both her bones and those of Geta were transferred by Maesa to the Mausoleum of Hadrian.[
