Attarsiya was a 15th-14th century BC military leader of Ahhiya. In the Hittite archives of c. 1400 BC he is described as a man from Ahhiya, a country identified with the Achaeans and Mycenaean Greece. The campaigns of Attarsiya, as well as his conflict with the Hittite vassal, Madduwatta, represent the first recorded Mycenaean Greek military activity on the Anatolian mainland, as well as the first conflict between Achaeans and Hittites.
