The Tawagalawa letter (CTH 181) is a fragmentary Hittite text from the mid 13th century BC. It is notable for providing a window into relations between Hittites and Greeks during the Late Bronze Age and for its mention of a prior disagreement concerning a city called Wilusa, generally identified with the archaeological site of Troy. The Tawagalawa letter was written by a Hittite king to a king of Ahhiyawa around 1250 BC. The author is generally identified as Hattusili III, though some scholars have argued that it was written by Muwatalli II. Since the surviving text is fragmentary, the identities of the author and addressee are not known for certain, and nothing can be inferred about the identity of its addressee. In the letter, the Hittite king seeks cooperation from the Ahhiyawan king in suppressing anti-Hittite activity in Western Anatolia. His particular concern was the activity of a warlord named Piyamaradu who had recently fled to Ahhiyawa-controlled territory after leading an unsuccessful rebellion in Lukka. Given Piyamaradu's apparent propensity for anti-Hittite activity, the author was concerned about his next moves and offered the Ahhiyawan king three proposals-- either extradite him to the Hittites, expel him from Ahhiyawa, or offer asylum on the condition that he not attempt any further rebellions. No surviving documents attest to the Ahhiyawan king's decision, though the subsequent decades saw an increase in Ahhiyawa control over Western Anatolia, suggesting that the appeal was rejected. The letter is notable in part for the tone adopted by the Hittite king. Though he scolds his Ahhiyawan counterpart for previously supporting Piyamaradu, the letter is respectful and conciliatory, and uses terms of address such as "my brother" normally reserved for rulers of major empires such as Egypt and Babylonia. Thus, the letter has been taken as evidence that the Ahhiyawa were seen as a growing power in the region.
