Doquz Khatun
13th-century Keraite princess and consort to Ilkhanate Khan, Hulagu

Doquz Khatun (also spelled Dokuz Khatun) (died 1265) was a princess of the Keraites who was married to Hulagu Khan; her husband was the founder of the Ilkhanate and a grandson of Genghis Khan.
Life
Doquz Khatun was possibly a granddaughter of the Keraite khan Toghrul, through his son Uyku or Abaqu. She was at first given to Genghis Khan and Börte's youngest son Tolui following the demise of her grandfather. After his death in 1232, she was wed to Hulagu, her step-son in levirate marriage. She was known to accompany Hulagu on campaigns. At the Siege of Baghdad (1258), the Mongols massacred tens of thousands of inhabitants, but through the influence of Doquz, the Christians were spared.
Some sources indicate that Doquz Khatun was an Assyrian by origin, who adhered the Church of the East, and is often mentioned as a great benefactor of the Christian faith. When Mongol envoys were sent to Europe, they also tried to use Doquz's Christianity to their advantage, by claiming that Mongol princesses such as Doquz and her aunt Sorghaghtani Beki were daughters of the legendary Prester John.
Doquz Khatun was a supporter of her step-son Abaqa and retained her influential position even after the death of her husband. She secured succession of Denha I to patriarchal throne of Church of the East in her capacity.

Why this record matters

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 16, 2026. The linked authority identifier is Q154196. None of the 1 selected statements returned an explicit reference. The first chronological checks are 1265, 1232 and 1258.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
