BOLOḠĀN (Būlūḡān) ḴĀTŪN, the name of three of the royal wives of the Mongol Il-khans in Iran. Of Mongol origin, the word Boloḡān, variously spelled in the Persian sources, means “sable”

1. Boloḡān Ḵātūn “Bozorg,” a relative of Būqāy Yārḡūčī (the judge), was Abaqa Khan’s (q.v.) ninth wife and was favored by him above Mertay Ḵātūn the Qūnqūrāt and Despīna Ḵātūn (daughter of Michael Palaeologus). She was the mother of Abaqa’s daughter Maleka and raised his grandson Ḡāzān as her own son. On Abaqa’s death in 680/1282, she was taken as a wife by his son Arḡūn Khan. In Jomādā II, 681/September, 1282, she was instrumental in securing the pardon of the vizier Ḵᵛāja Wajīh-al-Dīn Faryūmadī for his part in an alleged plot against Arḡūn. Arḡūn’s conspicuous reliance on her support and counsel in his struggle with Aḥmad Takūdār (Tegüder) in 683/1284 was such that the amir Būqā had to restrain him from pausing to confer with Boloḡān at the critical moment of his release from Aḥmad’s custody. Aḥmad Takūdār also treated her with respect (Rašīd-al-Dīn, ed. Jahn, 1957, pp. 54-55; Waṣṣāf, pp. 130-33). She died on 23 Ṣafar 685/20 April 1286 by the Kor river and her coffin was taken to Sajās, southwest of Solṭānīya, one of the alleged burial places of Arḡūn himself (see Zipoli, 1978). Some of her valuables were kept by Arḡūn, and the rest, including the lavish tokens of Abaqa’s affection for her, were given to Ḡāzān. Arḡūn later replaced her by another woman of the same name ref:http://www.iranicaonline.org/articles/bologan-katun-the-name-of-thr...

Childless, she takes care of her two stepsons Arghun and his brother

Buluqhan Khatun (died ca. 1286) (lit. "Queen Buluqhan"), also Bulughan, Bulukhan, Bolgana, Bulugan, or Zibeline for Marco Polo (Chinese language|Chinese: 卜鲁罕), was a 13th-century Mongol princess, and the principal wife of the Mongol Ilkhanid ruler Abagha (1234–1282). She belonged to the Mongol tribe of the Bayaut (also Baya'ud, Chinese: 伯牙吾). Her name 'Bulughan' means 'sable' in Mongolian language.

When Bulughan died in 1286, her step-son Arghun asked Kublai Khan to send him one of Bulughan's relatives as a new bride. The choice fell to Kökötchin ("Blue, or Celestial, Dame"), who was escorted by Marco Polo on her journey from Kaan-baligh (Beijing). The party traveled by sea, departing from the southern port city of Quanzhou and sailing to Sumatra, and then to Persia, via Sri Lanka and India. They arrived in 1291; however, Arghun had been killed before her arrival by conspirators, so Kökötchin married Arghun's son Ghazan, becoming his principal wife.

Though childless herself, she raised her step-grandsons (by Abagha's son Arghun) Ghazan and Öljeitü, both of whom later succeeded Arghun, and eventually converted to Islam. Arghun had Öljeitü baptized at birth, and gave him the name "Nicholas" after Pope Nicholas IV.[1]

When Bulughan died in 1286, her husband Arghun asked Kublai Khan to send him one of Bulughan's relatives as a new bride. The choice fell to Kökötchin ("Blue, or Celestial, Dame"), who was escorted by Marco Polo on her journey from Kaan-baligh (Beijing).
