Ignore the unhelpful statement the first person submitted. The answer to the question is: 2370bce
2000 BCE
The near east changed over time. At periods there were independent city-states as in the Greek world. Then various empires (Assyrian, Babylonian, Persian) absorbed them, just as the Greek city-states were eventually absorbed into Hellenistic kingdoms and eventually the Roman Empire.
The countries absorbed by Persia included Media, the Babylonian Empire, the remnant of the Assyrian Empire, the Lydian Empire and other peoples in Asia Minor, Thrace, Syria, Parthia, the peoples of Central Asia, Egypt, Libya.
The Persian Empire absorbed the Babylonian Empire.
The Nile Kingdom Of Nubia
Rome.
The ten northern tribes were absorbed into the Assyrian empire in the late 8th Century BCE .
They were absorbed into the expanding Roman Empire.
The Romans progressively absorbed the Greek world into the Roman Empire.
They absorbed the Medes, their previous rulers.
This proposition is based on incorrect premises. During the Archaic Period (which covered up to 600 BCE), Persia was not an empire, it was a tribal confederation which was subject to Media. And the Assyrian Empire was over - its residue existed in the shadow of the Babylonian Empire. From 550 BCE Persia absorbed Media, and used this combined strength to absorb the Babylonian Empire. It then expanded further over the next 50 years, under Kings Cyrus the Great, Cambyses and Darius the Great, to incorporate Asia Minor, Central Asia, the rest of the Middle East, Libya-Egypt and today's Pakistan.
Persia, a province of the Median empire, absorbed Media and, with this combined strength, King Cyrus (the Great) set out to take over the Babylonian empire, absorbing it into his growing empire.)
