‘The Old Assyrian colonies, 1950–1740 bce’ describes the period that follows the end of the Third Dynasty of Ur, which was one of breakup of empire and forging and breaking of alliances. This was also a period of extensive trade over great distances. The best evidence for trade during the beginning of the second millennium bce comes from Anatolia. Evidence suggests a close relationship between two cities 1,200 kilometers (about 750 miles) from each other: Kanesh and Assur in northern Mesopotamia. One of the texts that has been found is a copy of a treaty drawn up between the king of Kanesh and the Assyrian merchants.
