The Hittites were an Indo-European people of Anatolia who created an important empire in the 2nd Millennium BCE. All dating is subject to dispute, as is some of the ordering. The list of the Old Kingdom corresponds to O.R. Gurney's The Hittites (1952,1962)), while the list for the Empire corresponds to one of the dating schemes in Amélie Kuhrt's The Ancient Near East, c.3000-330 BC (1995,2000).
