The dating and sequence of Hittite kings is compiled by scholars from fragmentary records, supplemented by the finds in Ḫattuša and other administrative centers of cuneiform tablets and more than 3,500 seal impressions providing the names, titles, and sometimes ancestry of Hittite kings and officials.
