The Thirty Years' Truce or Truce of Khlat was a truce agreed to by Queen Tamar of Georgia and Al-Adil I, an Ayyubid Sultan of Egypt in October, 1210.
By 1208, the Kingdom of Georgia challenged Ayyubid rule in eastern Anatolia and besieged Khlat. In response Ayyubid Sultan al-Adil I assembled and personally led large Muslim army that included the emirs of Homs, Hama, and Baalbek as well as contingents from other Ayyubid principalities to support al-Awhad. During the siege, Georgian general Ivane Mkhargrdzeli accidentally fell into the hands of the al-Awhad on the outskirts of Khlat and was released only after the Georgians agreed to a thirty-year truce on following terms:[1]
The truce ended the Georgian menace to Ayyubid Armenia.[3] Georgia refrained from hostilities against enemy with whom Tamar the Great had signed a treaty, and the border or Christian-Muslim world was established. As the result Georgia abandoned its ambitions west of the river Araxes.
