^ Since the Western Roman Empire was not a distinct state separate from the Eastern Roman Empire, there was no particular official term that designated the Western provinces or their government, which was simply known at the time as the "Roman Empire". Terms such as Imperium Romanum Occidentalis and Hesperium Imperium were never in official usage or were invented by later medieval or modern historians long after the Western Roman court had fallen. In the ancient era, the Latin term that was often used was "S.P.Q.R." ("Senatus Populusque Romanus" ["Senate and People of Rome"] Latin) in documents, on flags and banners and carved/engraved on buildings ^ The deposition of Emperor Romulus Augustulus in 476 is the most commonly-cited end for the Western Roman Empire, but the last Western Roman Emperor, Julius Nepos, was assassinated in 480, when the title and notion of a separate Western Roman Empire were abolished. Another suggested end date is the reorganisation of the Italian Peninsula and the abolition of separate Western Roman administrative institutions under Emperor Justinian during the latter half of the 6th century. ^ The Theodosian dynasty Emperors Honorius and Valentinian III reigned from Ravenna. In the period between Valentinian and Glycerius, who once again reigned from northern Italy, most emperors appear to have reigned from Rome. Both Emperors Petronius Maximus and Anthemius reigned from and died in Rome. ^ The de jure last emperor, Julius Nepos, reigned for five years in exile from Spalatum in Dalamatia.

The Western Roman Empire was the western half of the Roman Empire, which was divided by Diocletian in 286 AD. The other half of the Roman Empire became known as the Eastern Roman Empire.

The Roman Empire had been in difficulties since 190 AD, when large Gothic tribes began moving into areas under Roman control. The Empire had weak leadership, which caused instability. Various power groups in the Roman armies kept trying to install their own emperors and killed those who belonged to other groups. That helped the invasions by the Germanic tribes.

Diocletian ended Rome's Crisis of the Third Century and tried to bring back stable government by dividing the empire into sections. The Western Empire included Iberia, France, southern Britain, Italy, North Africa and parts of Germany. The Eastern Empire included the Balkans, Turkey, the Levant and Egypt.

Rome ceased to be the capital from the time of the division. In 286, the capital of the Western Roman Empire became Mediolanum (now Milan). In 402, the capital was again moved, this time to Ravenna.

The division did not help the Western Empire, which came under increasing invasions from the north: the Ostrogoths, Huns, Franks, Visigoths and Burgundians. Its armies were brought back towards Rome and abandoned Britain and France. The Empire's economy could not cope since the increased need for military spending caused inflation. Citizens were unhappy with the rising taxes and rising prices.

In AD 398, Alaric led the Visigoths and began making attacks closer and closer to the capital. By 410, he had sacked Rome. In 455, the Vandals captured the city. In 476, the Goths captured the city.

The fall of the Western Roman Empire took place in 476 AD, when the leader of the Goths, Odoacer, removed Emperor Romulus Augustus. Odoacer became King of Italy, and the Western Roman Empire ended. By then, however, the empire had existed in name only, and the Emperor no longer had military, financial or political power.
