Like the Hyksos in Egypt, they adopted the manners and customs, the writing and language, of the conquered people, sometimes even their names.

The army, however, continued to be mainly composed of Kassite troops, and the native Babylonians began to forget the art of fighting.

The old claims to sovereignty in the west, however, were never resigned; but the Kassite kings had to content themselves with intriguing against the Egyptian government in Palestine, either with disaffected Canaanites, or with the Hittites and Mitannians, while at the same time they professed to be the firm friends of the Egyptian Pharaoh.

Burna-buryas in B.C.1400 writes affectionately to his "brother" of Egypt, begging for some of the gold which in Egypt he declares is as abundant "as the dust," and which he needs for his buildings at home.

He tells the Egyptian king how his father Kuri-galzu had refused to listen to the Canaanites when they had offered to betray their country to him, and he calls Khu-n-Aten to account for treating the Assyrians as an independent nation and not as the vassals of Babylonia.
The Assyrians, however, did not take the same view as the Babylonian king.
