WESTERN ROME broke up into 10 kingdoms (10 toes) and the Catholics saw to it that 3 were destroyed (according to prophecy). History agrees with me, not you.
Can you count? there are 7 foederaci here in 500 AD, yet all of them, were foederaci in the Roman Empire - they acknowledged the Roman Emperor in Byzantium as their overlord.
Can't you get this into your head - Rome didn't fall in 476 AD, it didn't collapse them. All that happened was the the entire empire fell once more under ONE Augustus - Emperor Zeno who sat in Constantinople.
