The seven heads are that of the Babylonian Empire, Medo/Persian Empire, Grecian Empire and Roman Empire. The ten horns represent the nations the Roman Empire scattered to when the deadly wound was put upon them,
Daniel 7:23-25;
Rev 13:3.
These ten nations were the Anglo-Saxons (Germans in Great Britain), the Franks (French), Suevi (Portuguese), Visigoths (Spanish), Burgundians (Swiss), Alemanni (Germans), Lombards (Italians), Ostrogoths, Heruli, and the Vandals in northern Africa. The last three being Ostrogoths, Heruli, and the Vandals had already been destroyed by the Roman Empire before their deadly wound came in 1798, but was healed in 1929.
The ten horns are ten kings who have not yet received their kingdoms as the Vatican's New World Order Headquarters and the United Nations Organization, One Security Council that claims authority over the world are waiting for ten permanent members. In 2009 the UNO divided the world into ten economic regions and each one will have a Jesuit Provincial set over them, but their end will come with the glory of the Lord striking them down when He returns with us His army. (Will study more about the army in Rev 19)
