The Assyrian Empire was at its height of power under the kings
Sennacherib, Esarhaddon, and Asshurbanipal. The states nominally subject
to the Assyrian king, paying tribute and homage, extended from the river
Halys, in Asia Minor, and the seaboard of Syria, on the west, to the
Persian Desert on the east; and from the Caspian and the Armenian
Mountains, on the north, to Arabia and the Persian Gulf, on the south;
and latterly included Egypt.
