Terken Khatun (wife of Ala ad-Din Tekish)

Terken Khatun also known as Turkan Khatun (Persian: ترکان خاتون‎‎, "the Queen of the Turks") was the Empress of the Khwarazmian Empire by marriage to of Shah Ala ad-Din Tekish, and the mother and de facto co-regent of Muhammad II of the Khwarazmian Empire.

Terken Khatun was from the Qanghli or the Bayads tribe of the Yemek, the daughter of the Kipchak Khan. According to Jalal ad-Din Mingburnu's biographer Muhammad Nasawai, majority of her son, Ala ad-Din Muhammad's, top commanders were from Terken Khatun's tribe, and the need to attach them to his side was one reason why the Shah lent so heavily on his mother for advice.

After the death of her partner, 'Ala' al-Din Tekish (1172-1200), she so dominated the court of their son, 'Ala' al-Din Muhammad II (1200-20) and quarreled so bitterly with his heir by another wife, Jalal al-Din, that she may have contributed to the impotence of the Khwarazmshahi kingdom in the face of the Mongol onslaught. She had a separate Divan and separate palace and the orders of the sultan were not considered to be effective without her signature. The Shah ruled the heterogeneou peoples without mercy. In face of Mongol attacks, Khwarazm empire, with a combined army of 400.000, simply collapsed. Harezmshah Muhammed had retreated to Samarkand towards the end of his domination and he had to leave the capital city of Gurgenç to her.
