See it on the History map →What happened
From 376, Goths fleeing the Huns crossed the Danube; mistreated by Roman officials, they rebelled and destroyed a Roman army at Adrianople in 378. Civil wars, tax strain and frontier pressure followed. Visigoths sacked Rome in 410, Vandals in 455. The West came to depend on Germanic generals, and in 476 one of them, Odoacer, deposed the teenage emperor Romulus Augustulus and named no successor. Kingdoms of Franks, Goths and others took over; the East continued.
Why it matters
It ended unified rule in Western Europe and opened the medieval era, as Germanic kings, Roman bishops and Latin culture blended into new societies.
How we know
Contemporary writers such as Ammianus Marcellinus and Sidonius Apollinaris, the later historian Procopius, law codes, and archaeology showing shrinking trade, simpler buildings and fewer coins in the 400s–500s.
Still debated
Violent collapse or gradual 'transformation'? Historians still argue. German historian Alexander Demandt catalogued 210 causes that writers have proposed.

▸Fall of the Western Roman Empire left standing, as Rome's surviving half, the Byzantine EmpireMostly agreed
The connection
From 395 the empire was split between two courts. The East was richer, more urban and protected by Constantinople's walls, so it rode out the 400s' invasions. When the West collapsed in 476, the eastern emperor became the only Roman emperor. Justinian later reconquered Italy and North Africa, but those gains proved short-lived.
When and how
Constantinople and the western provinces, 395–565; Odoacer, Emperor Zeno and, later, Justinian.
How sure are we?
Contemporary chronicles report that Odoacer sent the western imperial regalia to Constantinople, accepting Zeno as sole emperor.
Debates and open questions
Why the East survived when the West did not (wealth, geography, walls or luck) is debated.
▸Fall of the Western Roman Empire left a gap later filled by CharlemagneMostly agreed
The connection
After the western empire ended in 476, Germanic kingdoms ruled its lands. The Franks, who adopted Catholic Christianity under King Clovis around 500, became the strongest. Charlemagne extended Frankish rule over much of the old western empire and in 800 revived the title of emperor in the West, vacant for over 300 years.
When and how
Western Europe: Clovis's Frankish kingdom from about 481; Charlemagne ruled 768–814 and was crowned in Rome on Christmas Day 800.
How sure are we?
Gregory of Tours' History of the Franks; Frankish royal annals; Einhard's Life of Charlemagne; papal letters.
Debates and open questions
Whether Rome 'fell' or slowly transformed into these kingdoms is a major debate, which shapes how new Charlemagne's empire really was.
