Excerpts from Books and Wikipedia
First king was Ashur-ubalilt I (1365-1330); Last king was Tiglath-Pileser II (967-934);
"Between 1119 and 1032 BC, the Hittites collapse, and the prosperity of Assyria and Babylon withers. . . . The ebb of three civilizations in a western crescent—the Hittites, the Mycenaeans, the Egyptians—coincided with a sudden burst of power to the east. For a few brief years, while the wandering nomads and Sea Peoples were busy harassing the west, Assyria and Babylon brightened. . . . And so as Egypt descended into fractured disorder and darkness spread across the Greek peninsula, a similar fog rolled from the old Hittite lands to cover Mesopotamia." [Bauer: Ancient World, p. 285-90]
