It is a period marked by the steady growth of culture, manifesting itself in the erection of temples, in the construction of canals, and in the expansion of commerce.

Active relationships were maintained between Babylonia and distant Egypt.
This movement did not suffer an interruption through the invasion of the Cassites.

Though Nippur, rather than Babylon, appears to have been the favorite city of the dynasty, the course of civilization flows on uninterruptedly, and it is not until the growing complications between Babylonia and Assyria, due to the steady encroachment on the part of the latter, that decided changes begin to take place.
About 1500 B.C.the first traces of relationship between Babylonia and the northern Mesopotamian power, Assyria, appear.

These relations were at first of a friendly character, but it is not long before the growing strength of Assyria becomes a serious menace to Babylonia.

In the middle of the thirteenth century, Assyrian arms advance upon the city of Babylon.
