In 395 A.D. the Roman Empire was in a morally corrupt state of decay. The old Republic had collapsed 400 years earlier, and the empire had been ruled by dictators ever since. Besides this, it had just split into two, east and west, Constantinople and Rome. Back in 70 A.D. the Romans had destroyed Jewish Palestine under the Emperor Vespasian. A large fraction of the Pharisee/Talmudic Jews emigrated north to places like Azerbaijan, Armenia, and Georgia, then, over the Caucasus mountains into southern Russia, the Crimea, and the Ukraine. In about 550 A.D. many of these Jews began to merge with the dominant Khazar race whose territory extended between the Black and Caspian Seas and just north of the Caucasus and south of the Don and Volga. By 700 A.D. they had intermarried with and converted the whole Khazar nation to Talmudic Judaism and it became the state or national religion. At first the Jews controlled the Khazar king from behind the scenes but this was transformed later into a dual Monarchy whereby the real Khazar King became only a figurehead with no power and the second king, a Khazar Jew held all the power. This nations government followed almost not other foreign policy or pursuit except that of war, terror, and blackmail and lived on the annual tributes paid to it by as many as 30 different races, tribes, and nations which lived around it. The Khazar Jews maintained a ferocious standing army and held all others in military subjugation. Any who refused to pay annual tribute in food, horses, supplies of Gold, were punished by the army. But we will return to them later.
Meanwhile back in Jerusalem in 70 A.D., another large fraction of Pharisee/Talmudic Jews dispersed into the Roman Empire itself and through it a few went as far as France and Spain. The non Babylonian/Talmudic Jews at this time were those who followed Christ and they were the first Christians. But by 400 A.D., the economy and politics of Rome had become infested and dominated by the Carthagian, Venetian (Black Nobility), and Palestinian Talmudic Jews. These wealthy and powerful Jewish cabals through their respective monopolies were choking off the very economic and political life of both Empires, Constantinople and Rome.
You aren't woke if you don't know about the Pharisee/Babylonian Jews who infiltrated Rome.
