After a period of comparative decline in Assyria, it once more began to expand with the Neo Assyrian Empire (935–605 BC). This was to be the largest empire the region had yet seen, and under rulers such as Adad-Nirari II, Ashurnasirpal, Shalmaneser III, Semiramis, Tiglath-pileser III, Sargon II, Sennacherib, Esarhaddon and Ashurbanipal, Iraq became the centre of an empire stretching from Persia, Parthia and Elam in the east, to Cyprus and Antioch in the west, and from The Caucasus in the north to Egypt, Nubia and Arabia in the south.
