Band-i Qër (, meaning 'bitumen dam', also Romanized as Band-e Qër, Band-e Qir, and Band Qër; also known as Bid Ghir) is a village in Miyan Ab Rural District, in the Central District of Shushtar County, Khuzestan Province, Iran. At the 2006 census, its population was 446, in 73 families.
Band-i Qër lies on or adjacent to two earlier settlements. In the SÃÂsÃÂnid period, the town Rustam KuwÃÂdh (also spelled Rostag Kavad) flourished at the site. Rustam KuwÃÂdh was destroyed during the Arab/Muslim conquests of the seventh century CE.
Around this time, ÿAskar Mukram (, whose name means 'Mukram's encampment') was founded nearby, near the confluence of the canal ÃÂb-i Gargar and the river KÃÂrà «n. Although the early history of the settlement is obscure (with the early accounts of al-BalÃÂdhurë and al-Ṭabarë conflicting), the tenth-century Ḥudà «d al-ÿÃÂlam describes the town as large and prosperous, lying on both sides of the ÃÂb-i Gargar. A Bà «yid mint was based there at the same time. Later in the Middle Ages, however, the town fell into disuse. Noted inhabitants included Abà « HilÃÂl al-ÿAskarë (d. after 1009).
The extensive ruins of ÿAskar Mukram remain at Band-i Qër.
