In AD 395, a few decades before its Western collapse, the Roman Empire formally split into a Western and an Eastern one, each with their own emperors, capitals, and governments, although ostensibly they still belonged to one formal Empire. The Western Roman Empire provinces eventually were replaced by Northern European Germanic ruled kingdoms in the 5th century due to civil wars, corruption, and devastating Germanic invasions from such tribes as the Goths, the Franks and the Vandals by their late expansion throughout Europe. The three-day Visigoths's AD 410 sack of Rome who had been raiding Greece not long before, a shocking time for Graeco-Romans, was the first time after almost 800 years that Rome had fallen to a foreign enemy, and St. Jerome, living in Bethlehem at the time, wrote that "The City which had taken the whole world was itself taken." There followed the sack of AD 455 lasting 14 days, this time conducted by the Vandals, retaining Rome's eternal spirit through the Holy See of Rome (the Latin Church) for centuries to come. The ancient Barbarian tribes, often composed of well-trained Roman soldiers paid by Rome to guard the extensive borders, had become militarily sophisticated 'romanized barbarians', and mercilessly slaughtered the Romans conquering their Western territories while looting their possessions.
