Boloḡān Ḵātūn “Ḵorāsānī,” daughter of Amir Tesūy (whose mother was Menglī Tegen, the daughter of Arḡūn Āqā) was first married to Ḡāzān Khan before his accession; Rašīd-al-Dīn records her giving birth to a stillborn child near Fīruzkūh in 690/early 1291, and she accompanied Ḡāzān part of the way on his second decisive advance against Bāydū in 694/1295. She gave shelter to her kinsman, a young son of Nowrūz (her maternal uncle) Amir Nawruz of the Oirats, on the fall of his family in 696/1297, and her name is linked with another less successful mediation (Rašīd-al-Dīn, ed. Jahn, 1940, pp. 31, 83, 86, 111).

After Ḡāzān’s death, she became the seventh wife of Öljeytü on 8 Ḏu’l-qaʿda (or possibly Ḏu’l-ḥejja) 704/2 June (July) 1305. This third Boloḡān died on 5 Ṣafar 708/25 July 1308, perhaps in Baghdad, where she is said to have constructed a town (šahr) called after her Ḵorāsān. The endowments (waqf) of the ḵānāqāh that she built there were then entrusted to Rašīd-al-Dīn (Kāšānī, pp. 44, 82).]
