Mursili II
The Hittite king Suppiluliumas's treaty with Hakkani of Hayasa addresses "the people of Hayasa." According to Igor Diakonoff, this likely suggests that the Hayasans had a peoples' assembly or council of elders. Similarly, Mursili II later conducted negotiations with "the elders" of Azzi. The nearby land of Pahhuwa may have had a similar governing council.
