The Western Roman Empire was the Roman state's western half. Honorius ruled it after Theodosius I died in 395. Its imperial court in Italy ended in 476. The recognised claimant Julius Nepos survived until 480. De Imperatoribus Romanis: Honorius De Imperatoribus Romanis: Julius Nepos
Its main late courts were Milan and Ravenna, not always the city of Rome. The Eastern Roman Empire continued while western emperors lost land and depended increasingly on powerful generals. De Imperatoribus Romanis: Valentinian III
TL;DR: The West was a government with changing courts, armies and provinces. Honorius received it after Theodosius. Generals such as Stilicho and Aetius held major power. Land losses reduced its resources. Odoacer ended the resident office in Italy, and Nepos's later death ended the recognised western claim.

What changed in 395?
Theodosius I's death left Honorius in the West and Arcadius in the East. In theory, the Roman imperial world remained one entity. In practice, each court had its own ruler, advisers and political problems. De Imperatoribus Romanis
This was not the first time Roman emperors had shared rule. Earlier arrangements had divided responsibility across a state too large for one ruler to supervise easily. The importance of 395 lies in the lasting separate histories that followed. World History Encyclopedia: Western Roman Empire
The young western ruler relied heavily on advisers and military commanders. Rule depended on troops, funds and allies. Rival claimants could take those away. An emperor's title alone could not settle those questions.
The Theodosius biography explains the father and succession behind the division. The Roman Empire timeline places it among the earlier changes in shared rule.
Milan, Ravenna and Rome
Honorius's court moved from Milan to Ravenna in 402 after the Visigothic invasion of Italy. Ravenna offered a heavily defended and difficult approach. Later western emperors usually kept their court there, although Rome still mattered politically and ceremonially. De Imperatoribus Romanis
This helps explain a common confusion about the fall. The western emperor's fall did not destroy Rome itself. The city outlived the office. The office could be ended at a court based elsewhere.
Rome remained a centre of aristocratic life, sacred power and the memory of power. Its sack was therefore a major shock even when the emperor was not living there. The government and its most famous city had different kinds of importance.
A map of court cities is also different from a map of land. Moving an emperor to a safer residence did not bring lost provinces back under his control. It protected one centre while leaving wider problems unresolved.
Stilicho: power behind Honorius
Stilicho was the chief military figure early in Honorius's reign. His family links to the court reinforced his position: Honorius married two of his daughters in succession. Stilicho fought to defend Italy while managing the risks posed by rival forces and court politics. De Imperatoribus Romanis
His execution in 408 removed that leading commander. Honorius then faced Alaric without the same military adviser. Negotiations and resistance failed to produce a lasting settlement before Rome was sacked in 410.
The episode shows how internal political choices could affect external defence. A ruler might fear a powerful general. But removing him could create a new weakness. The emperor and army were tied together even when their leaders distrusted each other.
For the attackers and the sack's place in the larger story, see who defeated the Roman Empire. A sack could be devastating without at once ending the government.
Aetius and Valentinian III
Valentinian III became emperor in 425. His mother, Galla Placidia, held great influence in his early reign. Later, much army power lay with Aetius, the leading general. De Imperatoribus Romanis: Valentinian III
The West during this period lost effective control over major regions. Vandal power in North Africa was especially damaging. Other groups held large areas in Spain and Gaul. A smaller tax base made the remaining government harder to sustain. World History Encyclopedia
Valentinian killed Aetius in 454. The emperor was himself murdered the following year by former supporters of the general. These deaths broke the remaining stability associated with the ruling dynasty and accelerated the struggle over succession.
The pattern resembled the earlier conflict around Stilicho. Army power and imperial right to rule could support each other. But a violent break between them weakened both. Later emperors often ruled within a much narrower area.
Selected western emperors
The entries follow De Imperatoribus Romanis, De Imperatoribus Romanis: Valentinian III, De Imperatoribus Romanis: Majorian, De Imperatoribus Romanis, World History Encyclopedia.
These rulers show the main stages. Many brief claimants held office between them.
| Emperor | Reign or western claim | Main point |
|---|---|---|
| Honorius | 395–423 | Received western rule; the court moved to Ravenna |
| Constantius III | 421, as co-emperor | A powerful general briefly held the imperial title |
| Valentinian III | 425–455 | Dynastic legitimacy survived alongside major losses |
| Majorian | 457–461 | Tried to recover territory and strengthen government |
| Julius Nepos | 474–480; out of Italy from 475 | Retained a recognised claim from Dalmatia |
| Romulus Augustulus | 475–476 | Last western emperor to rule in Italy |

The emperors of Rome page places these rulers in the longer imperial sequence. The late western office had become much less secure than the earlier title might suggest.
Majorian's recovery attempt
Majorian tried to rebuild western power, including in Gaul and Spain. His surviving laws also show efforts to address problems in government and protect public buildings. The West still produced active rulers who sought recovery. De Imperatoribus Romanis
His dependence on military politics remained a danger. Ricimer, a powerful general, had helped him rise and later turned against him. Majorian's fall showed how an emperor could lose office despite efforts to restore the state.
The late history is also more than a sequence of passive rulers awaiting collapse. Some campaigns and reforms aimed to reverse losses. Their failure helps explain the end without requiring a belief that recovery was impossible at every earlier point.
The final western office
Nepos lost Italy when Orestes rebelled in 475 and placed Romulus on the throne. Nepos remained in Dalmatia and kept eastern support. Odoacer's defeat of Orestes and deposition of Romulus in 476 then ended the resident western court. De Imperatoribus Romanis World History Encyclopedia
No replacement emperor was installed in Italy. Odoacer ruled as king while maintaining a relationship with eastern power. Nepos's death in 480 removed the surviving recognised western claimant.
See when did the Western Roman Empire fall for the detailed endpoint. The last Roman emperor page compares Nepos, Romulus and the final eastern emperor.
Verdict: Western Roman Empire
The Western Roman Empire lost provinces and tax income. Its shrinking court faced repeated struggles over army command. Use 476 for the end of emperors resident in Italy, with 480 for Nepos's recognised claim. The East's survival shows why this was the western end of a wider Roman story.
