Alaric I was the first king of the Visigoths, from 395 to 410. He rose to leadership of the Goths who came to occupy Moesia—territory acquired a couple of decades earlier by a combined force of Goths and Alans after the Battle of Adrianople.
Honorius was Roman emperor from 393 to 423. He was the younger son of emperor Theodosius I and his first wife Aelia Flaccilla. After the death of Theodosius in 395, Honorius, under the regency of Stilicho, ruled the western half of the empire while his brother Arcadius ruled the eastern half. His reign over the Western Roman Empire was notably precarious and chaotic. In 410, Rome was sacked for the first time since the Battle of the Allia almost 800 years prior.
Galla Placidia, daughter of the Roman emperor Theodosius I, was a mother, tutor, and advisor to emperor Valentinian III. 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 until her death.

Constantine III was a common Roman soldier who was declared emperor in Roman Britain in 407 and established himself in Gaul. He was recognised as co-emperor of the Roman Empire from 409 until 411.
The end of Roman rule in Britain occurred as the military forces of Roman Britain withdrew to defend or seize the Western Roman Empire's continental core, leaving behind an autonomous post-Roman Britain. In 383, the usurper Magnus Maximus withdrew troops from northern and western Britain, probably leaving local warlords in charge. In 407, the usurper Constantine III took the remaining mobile Roman soldiers to Gaul in response to the crossing of the Rhine, and external attacks surged. The Romano-British deposed Roman officials around 410 and government largely reverted to the city level. That year Emperor Honorius refused an appeal from Britain for military assistance. The following decades saw the collapse of urban life and the beginning of Anglo-Saxon settlement.
Constans II was the son of Western Roman emperor Constantine III, and served as his co-emperor from 409 to 411. Constans was a monk prior to his father being acclaimed emperor by the army in Britain in early 407, an act of rebellion against the ruling emperor Honorius. He was summoned to Gaul, appointed to the position of caesar (heir) and swiftly married so that a dynasty could be founded. In Hispania, Honorius's relatives rose in 408 and expelled Constantine's administration. An army under the generals Constans and Gerontius was sent to deal with this and Constantine's authority was re-established. Honorius acknowledged Constantine as co-emperor in early 409 and Constantine immediately raised Constans to the position of augustus (emperor), theoretically equal in rank to Honorius as well as to Constantine. Later in 409 Gerontius rebelled, proclaimed his client Maximus emperor and incited barbarian groups in Gaul to rise up. Constans was sent to quash the revolt, but was defeated and withdrew to Arles. In 410, Constans was sent to Hispania again. Gerontius had strengthened his army with barbarians and defeated Constans; the latter withdrew north and was defeated again and killed at Vienne early in 411. Gerontius then besieged Constantine in Arles and killed him.
The Battle of Pollentia was fought on 6 April 402 between the Romans under Stilicho and the Visigoths under Alaric I, during the first Gothic invasion of Italy (401–403). The Romans were victorious, and forced Alaric to retreat, though he rallied to fight again in the next year in the Battle of Verona, where he was again defeated. After this, Alaric retreated from Italy, leaving the province in peace until his second invasion in 409, after Stilicho's death.
The sack of Rome on 24 August 410 AD was undertaken by the Visigoths led by their king, Alaric. At that time, Rome was no longer the administrative capital of the Western Roman Empire, having been replaced in that position first by Mediolanum in 286 and then by Ravenna in 402. Nevertheless, the city of Rome retained a paramount position as "the eternal city" and a spiritual center of the Empire. This was the first time in almost 800 years that Rome had fallen to a foreign enemy, and the sack was a major shock to contemporaries, friends and foes of the Empire alike.
