Ghias ad-Din

The consort of Queen Rusudan was a younger son of 'Abdu'l Harij Muhammad Mughis ad-din Tughril Shah, the Seljuq emir of Erzurum, and his wife, a daughter of Sayf al-Din Begtimur, the ruler of Ahlat.

The Georgian historian Prince Ioann, writing in the early 19th century, posits that Rusudan's husband was named Dimitri (Demetrius) upon his conversion to Christianity in Georgia.

[7] The contemporary Arab scholar Abd al-Latif al-Baghdadi also confirms that it was Rusudan who opted for the Seljuq prince, but Ali ibn al-Athir states that the emir of Erzurum himself proposed the marriage in order to defend his country from the Georgian encroachments.

After the Georgians rejected the emir's request on account of his being a Muslim, he ordered his son to convert to Christianity, the fact that is described by ibn al-Athir as "a strange turn of events without parallel".

[9] Reporting her scandalous love affairs and adulterous way of life, ibn al-Athir recounts that on one occasion Rusudan was surprised by her husband in bed in the arms of a slave ("mamluke").

[6] Evidence suggests he was devoid of the high status and prestige enjoyed by earlier Georgian king-consorts, especially Rusudan's father David Soslan, the husband of Queen Tamar.
