The Babylonian Empire began in the Valley of the Euphrates, the cradle of the human race, and extended west to Armenia and Palestine.
The Persian Empire extended further west, and reached to the whole of Asia Minor and Egypt.
The Grecian Empire extended still further west, originating in Europe in the territory (Greece) from which it made its conquests.
The Roman Empire was the greatest of all the four world-wide empires, both in extent of territory and in power. The Roman power in Italy conquered the Grecian Empire, and extended also west of Italy, to Spain, France, and Britain. Roughly speaking it was west of the Rhine and south of the Danube, and did not include Germany or Russia. It extended its hold on the north coast of Africa.
The Second, Third and Fourth Empires held Egypt, the Roman adding the whole of the North African littoral as known by us today under the names of Morocco, Algiers, Tunis, and Tripoli.
Note how the movement was from east to west. Today the interest is gravitating from west to east, and Palestine is rapidly becoming the strategic center of the world. Surely the signs are ominous. The world is getting ready for its final battles.
