Following this, the Hittites entered a weak phase of obscure records, insignificant rulers, and reduced domains. This pattern of expansion under strong kings followed by contraction under weaker ones, was to be repeated over and over through the Hittite Kingdom's 500-year history, making events during the waning periods difficult to reconstruct. The political instability of these years of the Old Hittite Kingdom can be explained in part by the nature of the Hittite kingship at that time. During the Old Hittite Kingdom prior to 1400 BC, the king of the Hittites was not viewed by his subjects as a "living god" like the Pharaohs of Egypt, but rather as a first among equals. Only in the later period from 1400 BC until 1200 BC did the Hittite kingship become more centralized and powerful. Also in earlier years the succession was not legally fixed, enabling "War of the Roses" style rivalries between northern and southern branches.
