In Daniel 2 & 7 the Bible prophesied a time period of world wide oppression and despotism over all true believers measured by four empires. The first one was Nebuchadnezzar's Babylon named in Daniel 2. The 2nd and 3rd empires, Medo\Persia and Greece named in Daniel 8. Then the Roman, described as conquering the remainder of the Greek Empire in Daniel 11:40-44 and named all over the New Testament. These empires spanned a time period starting from when Babylon first conquered Judea in 597 BC until the Roman Empire fell when what had been its capitol since 333 AD, Constantinople, fell to the Turks in 1453 AD.
