The Roman Empire was breaking up,
but was saved by two strong emperors, Divocletian and
Constantine.
When Constantine died
Rome split into west and east Rome. After the merciless Emperor Alexzander Severous in 235 A.D. the government broke down completely. This was the beginning of the end of Rome.
The
East Roman Empire took back part of Italy and North Africa from the barbarians. The land East Rome took over was taken away again.
In 455
A.D. Rome was plundered again by another barbarian horde, the Vandals. The western Roman
Empire no longer existed, all the providence where barbarian kingdoms.
Cut off from
the west the Byzantine Empire developed its own brilliant civilization, which lasted for
1000 years after imperial Rome had fallen.
The Roman
Empire lasted about 700 years, but its Roman civilization lasted longer. The Roman Empire
was recognized as the greatest empire.
