On his list of the greatest commanders during the reign of Shah Abbas I (r. 1588–1629), the Safavid-era historian Iskandar Beg Munshi included Maqsud Sultan Kangarlu.
[2] When Ottoman soldiers attacked the region later that year, Maqsud Sultan Kangarlu was ordered by Shah Abbas I to evacuate the entire area—including the Armenian community in the city of Julfa—to Qaradagh and Dizmar.
Around 1500, when the Ustajlu migrated into the Azerbaijan region, a large number of Kangarlu tribesmen settled north of the Aras River.
[1] In 1747, a member of the Kangarlu tribe, Heydar Qoli Khan, established the Nakhichevan Khanate under Iranian suzerainty.
[4] J. M. Jouannin, writing in 1819, mentioned the Kangarlu as "a small tribe established in Persian Armenia, on the shores of the Aras, and numbering up to four or five thousand individuals.
Later, when Shah Abbas II (r. 1642–1666) sought to repopulate the frontier regions of his realm, these individuals were granted permission to return to their original pastures.
There is still a settlement called Kangarlu between Salmas and Khoy, where one clan that Maftun Donbul and Valili Baharlu mentioned lived.
