Šuwardata (Shuwardata), also Šuardatu, is understood by most scholars to be the king of the Canaanite city of Gath (Tell es-Safi), although some have suggested that he was the 'mayor' of Qiltu (Keilah?, or Qi'iltu), during the 1350-1335 BC Amarna letters correspondence. Šuwardata was the author of 8 letters to the Egyptian pharaoh.
Besides letters EA 283, and EA 366, (EA for 'el Amarna'), only letter 280 tells of intrigues: See Labaya, or Abdi-Heba, as EA 280 claims: "Moreover, Lab'ayu who used to take our town, is dead, but now [an]other Lab'ayu is 'Abdi-Heba, and he seizes our town."
The other 5 letters do refer to the following: Qeltu-(Qiltu, Keilah:); silver (as mercenary pay); the Sun, (as Rê); the archer-forces; and the only reference to Rahmanu, an Egyptian official, (letter EA 284, "The powerful hand of the king").
All Šuwardata's letters are addressed to the pharaoh.
Šuwardata must have been an important regional individual, since he claims 30 cities, sub-cities, or city-states have been warring with his city.
