"8 “The beast that you saw was, and is not, and is about to come up out of the abyss and [
h]go to destruction. And those who live on the earth, whose names have not been written in the book of life from the foundation of the world, will wonder when they see the beast, that he was, and is not, and will [
i]come. 9 Here is the mind which has wisdom. The
seven heads are seven mountains upon which the woman sits, 10
and they are seven kings;
five have fallen, one
is, the other has not yet come; and when he comes, he must remain a little while. 11 The beast which was, and is not, is himself
also an eighth and is one of the seven, and he goes to destruction. 12 The ten horns which you saw are ten kings who have not yet received a kingdom, but they receive authority as kings with the beast for one hour. 13 These have one [
j]purpose, and they give their power and authority to the beast."
These cannot be Empires. Why not? God gave Daniel a vision of only four empires. Four consecutive empires, with a revived fourth to come. (Which could be why it says that there is an eigth that is not counted among the seven, but is an eighth, which is the beast himself, and, as the seven are Roman Emperors, this eighth is one of them in that he is also a Roman Emperor, over a revived Roman Empire. He is also the one in the 70 weeks prophecy, the one who is destroyed at the end of the 70th week. The one who blasphemes God, according to Daniel. Note that in linking to Daniel, this is the fourth of the five beasts, with the ten horns. And as the beast is an eight king, the mark is of him, which God shares that the mark is that of a man, not an empire.
There have only been four successful consecutive empires in the history of the world. There have been other empires (attempted), but they faded away, and did not become another empire. With the four, the Babylonian Empire was given the Medo Persians, and then to the Greeks, and finally the Romans. The Roman Empire ceased to exist in 1453 AD, with the overthrow of Constantinople (Constantine's city) by the Turks. That ended the Eastern Roman Empire. In Daniel's prophecy of the statue of Nebuchadnezzar, Jesus did not come to destroy it all until AFTER Rome had fallen and the iron and clay form of the revived Roman Empire was in place.
