The dating and sequence of the Hittite kings is compiled from fragmentary records, supplemented by the recent find in Hattusa of a cache of more than 3500 seal impressions giving names and titles and genealogy of Hittite kings. All dates given here are approximate, relying on synchronisms with known chronologies for neighbouring countries and Egypt.
Little is known of the rulers of the Middle Kingdom period. The sequence here still largely follows Bryce (1998), but the short (or low) chronology is used.
McMahon (1989) lists Hattusili II and Tudhaliya III in inverse order. Bryce, among others, does not distinguish a Middle Kingdom. Instead he ends the Old Kingdom with Muwatalli I and begins the New Kingdom with Tudhaliya I. Nor is Tudhaliya "the Younger" generally included in Hittite king lists, as he was assassinated upon the death of his father, Tudhaliya II.
