Tamar Gurju Khatun (Georgian: გურჯი-ხათუნი, romanized: gurji-khatuni; also Gürgü Hatun, fl.

[3] Gurju Khatun was the daughter of Queen Rusudan of Georgia and the Seljuk prince Ghias ad-Din, a grandson of Kilij Arslan II.

Like most Georgians, Tamar initially remained an Eastern Orthodox Christian but is known to have converted to Islam at a later point, after unproven accusations (by her own mother) of a secret affair between her and her cousin David Ulu, which put an end to previously harmonious relationship with her husband.

This emblem, known as shir-u hurshid (Lion and Sun), later became widespread in the Islamic world (though its origins date back to much earlier times).

After the death of Kaykhusraw in 1246, the government of the sultanate was seized by the Mu'in al-Din Parwana who married Gurju Khatun.
