Bulaqs

[2][3][4] As already Gyula Németh noted, the mi̯əu-lôk[5] or miə̯u-lâk ~ bulaq is etymologically related to the colour of horses which was a usual tribal designation on the steppe.

[2][6] Dezső Pais states that the name originates from the Turkic balxu, (bal ("slice")+-ku or -xu suffix) meaning "branch" or "part".

By 766 they were in possession of the cities of Suyab and Talas (in Arabic record: T. w. l. s., in Chinese: To-lo-se[6]) around which formed Karluk yabghu (756–940) and Kara-Khanid Khanate (840–1212).

[1] According to Lajos Tardy the name Ivlach and Ivlat, mentioned by Archbishop Johannes de Galonifontibus in 1404, refers to William of Rubruck's account,[16] which István Ferenczi related to the Bulaqs.

[17] Ferenczi argued that the records of slave sales from Kaffa also suggest that the word "Ivlach" denotes the Bulaqs, as well the Aulâq people, mentioned by Abu al-Ghazi Bahadur with the Russians, Hungarians and Bashkirs.

[19][20] The remark by Simon of Kéza from his work Gesta Hunnorum et Hungarorum about the Székelys living in the mountains which they shared with the Vlachs, where mingled with them, and adopted their alphabet,[21] sparked a controversy about the Old Hungarian script (Rovás), while other scholars noticed that Simon did distinguish between Ulahis[22] (Vlachs) and Blackis and identified the Blacki people with the Bulaqs.

[25] Prominent Hungarian linguist, Gyula Németh notes in his work A magyar rovásírás that the writings found in the Talas river valley show close similarity.

[26] A diploma of King Andrew II and a letter of Pope Innocent III, both written in 1222, mention the "land of the Blacs" (Terra Blacorum) between the Olt and the Carpathians.

Pritsak identifies this people with the Cumans,[29] while Ervin Láczay believes that Sturluson referred to the "forest of the Blacs and Pechenegs" (silvam Blacorum et Bissenorum), to which the Transylvanian Saxons were given access in 1224.

[32] French sinologist Paul Pelliot also tried to prove that the Illac and Lac recorded by Marco Polo, William of Rubruck and Roger Bacon aren't identical with the Ulac (Vlach).

[35] László Rásonyi, after protractedly analyzing Transylvanian toponyms and personal names, found the linguistic evidence to prove Bulaq presence there sufficient.

[36] György Bodor says that diplomas verify that in 1225 the Transylvanian Bulaqs, along with many other border guarding peoples were annexed by the Székely seats and assimilated.
