The site of Assur, a name eventually to be applied to the city, to the country, and to the principal god of the yet-to-emerge Assyrians, is revealed by archaeology to have been originally occupied about 2500 BCE by a tribe that probably had reached the Tigris River either from Syria or from the south. (The oldest remains of the city will one day be discovered in the foundations of the Ishtar temple, as well as at the Old Palace.)
