Flavius Honorius was Roman emperor from 393 to 423. He was the younger son of emperor Theodosius I and his first wife Aelia Flaccilla, and brother of Arcadius, who ruled the eastern half of the empire from 395, when their father died, until his death in 423. In 410, during Honorius's reign over the western Roman Empire, Rome was sacked for the first time in almost 800 years.
Galla Placidia, daughter of the Roman emperor Theodosius I, was a mother, tutor, and advisor to emperor Valentinian III, and a major force in Roman politics for most of her life. She was queen consort to Ataulf, king of the Visigoths from 414 until his death in 415, briefly empress consort to Constantius III in 421, and managed the government administration as a regent during the early reign of Valentinian III.

Valentinian III was Roman emperor in the West from 425 to 455. Made emperor in childhood, his reign over the Roman Empire was one of the longest, but was dominated by powerful generals vying for power amid civil wars and the invasions of Late Antiquity's Migration Period, including the campaigns of Attila the Hun.
Constantius III was Roman emperor of the West in 421, from 8 February until his death on 2 September. He earned his position as Emperor due to his capability as a general under Honorius, achieving the rank of Magister militum by 411. That same year, he was sent to suppress the revolt of Constantine III, a Roman general who declared himself emperor. Constantius led his army to Arles in Gaul, the capital of Constantine III, and defeated Gerontius, a general rebelling against Constantine, before himself besieging Arles. After defeating a relief force led by Edobichus, Constantius convinced Constantine to surrender, promising safe retirement, but betrayed and beheaded him as soon as he surrendered. Constantius then went on to lead campaigns against various barbarian groups in Hispania and Gaul, recovering much of both for the Western Roman Empire. Constantius was proclaimed Western Roman Emperor by Honorius on 8 February 421. He reigned for seven months before dying on 2 September 421.
Athaulf was king of the Visigoths from 411 to 415. During his reign, he transformed the Visigothic state from a tribal kingdom to a major political power of Late Antiquity.
Jovinus was a Gallo-Roman senator and claimed to be Roman Emperor.
Justa Grata Honoria, commonly referred to during her lifetime as Honoria, was the older sister of the Western Roman Emperor Valentinian III. She is famous for her plea of love and help to Attila the Hun, which led to his proclamation of his claim to rule the Western Roman Empire.
Bonifatius was a Roman general and governor of the diocese of Africa. He campaigned against the Visigoths in Gaul and the Vandals in north Africa. An ally of Galla Placidia, mother and advisor of Valentinian III, Bonifacius engaged in Roman civil wars on her behalf against the generals Felix in 427-429 and Aetius in 432. Although he defeated the latter at the Battle of Rimini, Bonifacius suffered a fatal wound and was succeeded by his son-in-law Sebastianus as patricius of the Western Roman Empire.
The Theodosian dynasty was a Roman imperial family that produced five Roman emperors during Late Antiquity, reigning over the Roman Empire from 379 to 457. The dynasty's patriarch was Theodosius the Elder, whose son Theodosius the Great was made Roman emperor in 379. Theodosius's two sons both became emperors, while his daughter married Constantius III, producing a daughter that became an empress and a son also became emperor. The dynasty of Theodosius married into, and reigned concurrently with, the ruling Valentinianic dynasty, and was succeeded by the Leonid dynasty with the accession of Leo the Great.
The Mausoleum of Galla Placidia is a Late Antique Roman building in Ravenna, Italy, built between 425 and 450. It was added to the World Heritage List together with seven other structures in Ravenna in 1996. Despite its common name, the empress Galla Placidia was not buried in the building, a misconception dating from the thirteenth century; she died in Rome and was buried there, probably alongside Honorius in the Mausoleum of Honorius at Old Saint Peter's Basilica.
The Valentinianic or Valentinian dynasty was a ruling house of five generations of dynasts, including five Roman emperors during Late Antiquity, lasting nearly a hundred years from the mid fourth to the mid fifth century. They succeeded the Constantinian dynasty and reigned over the Roman Empire from 364 to 392 and from 425 to 455, with an interregnum (392–423), during which the Theodosian dynasty ruled and eventually succeeded them. The Theodosians, who intermarried into the Valentinian house, ruled concurrently in the east after 379.
