According to the current understanding, Mira's northern border with the Seha River Land was marked by the Karabel relief.This was first proposed in 1975 by Hans Gustav Güterbock and confirmed by John David Hawkins decipherment of the inscription on the relief in 1998.[2] Borders with other territories, like Pitašša, Maša, and the kingdom of Arzawa are only attested in limited time periods.After the successful conclusion of the Arzawa campaign by Šuppiluliuma's son and successor Muršili II, Mašḫuiluwa was installed in Mira as a vassal ruler and granted 600 men as a personal guard.Mira is mentioned in around twenty, mostly fragmentary, cuneiform tablets found at Boğazkale (Ḫattuša) from the 14th and 13th centuries BC.
