The Antichrist’s empire is described in Revelation as a beast with seven heads and ten horns. Revelation 17:12 says the ten horns are ten kings that will rule with the Antichrist for a short time. The ten kingdoms will come out of the Roman Empire. Rome controlled North Africa, the Middle East and most of Western Europe. Well, the Antichrist will defeat many countries in North Africa and the Middle East during the Daniel 11:22 War. Likewise, the ten kingdoms will be to the west of Israel.
They’ll also be powerful enough to stop the Antichrist in his first attempt to invade Jerusalem. After the ten kingdoms come to power together, the Antichrist will emerge and remove three of them, becoming their new leader. They’ll then attack Babylon the Great.
So, the ten-kingdom coalition will consist of nations in Western Europe that were once controlled by the Roman Empire. Some likely candidates include Italy, Greece, France, Austria, Belgium, Germany, the Netherlands, Portugal, Spain, the United Kingdom or Switzerland. It’s also possible London is Babylon the Great and the United Kingdom rules over the ten kingdoms before the Antichrist. Whatever their identity may be, the ten kingdoms won’t be a very impressive group. They will start out as puppets of Babylon the Great and they will become puppets of the Antichrist.
