The greatest tragedy of European history.
If you study early Christianity you can understand that it played a significant role in the downfall of the Roman Empire. The Romans fed the Christians to Lions but they could not control the message.
The philosophical notion that there is life after death is an extremely potent weapon.
The Christians did not fear death as they believed in an after-life.
This spread like wildfire throughout the Roman Empire (there were more slaves than Roman Citizens) to such an extent that the Roman Emperor himself converted to Christianity.
(In an attempt to control the message.)
Indeed the city that he founded, Constantinople became the greatest civilisation (Byzantine).
Until it was over-run by the Turkish hordes from central Asia.
Since the fall of the Byzantine empire the banner was passed to Russia.
The
coat of arms of the Russian Federation derives from the earlier
coat of arms of the
Russian Empire which was abolished with the
Russian Revolution in 1917. Though modified more than once since the reign of
Ivan III (1462–1505), the current coat of arms is directly derived from its mediaeval original, with the
double-headed eagle having
Byzantine and earlier antecedents from long before the emergence of any Russian state.
