This area, encompassing the bridge and the fortress, eventually evolved into the city of Dež-Pol or Dezfūl, although this name was not commonly used until the 12th century.

The stone foundation of the bridge is still visible, while the upper part underwent several brick reconstructions during the early Islamic, Saljuq, and Qajar periods.

[7] According to George Curzon, who visited the area in the late 19th century, the principal local industry in Dezfūl was indigo, with 120 factories in the town.

The differences between Dezfuli and Shushtari are mainly a result of variations in the detailed sound patterns of the language.

The city lies at the foot of the Zagros Mountains and has a history that dates back to the Sassanian era.

[18] Dezful sits close to the foothills of the Zagros Mountains on the main north-south highway from Tehran to Ahvaz, the provincial capital of Khuzestan.

Other major agricultural products of the šahrestān include wheat, barley, clover, alfalfa, sesame, maize, and grass peas; sheep are the most important livestock[23] The Dezful reed pen is one of the important commercial products that has been cultivated in Dezful for the past three hundred years and is recognized as the finest reed pen at the national and global levels [citation needed].

The craft of varshoosazi (the making of varsho items) in Iran dates back to the Safavid era, but its peak occurred during the Qajar period and continued into the Pahlavi dynasty.

Artisans from Isfahan, Borujerd, and Dezful were the first to learn how to produce varsho crafts by observing Russian samovars and other products.

The varshoosazi industry reached its height in Iran, particularly in the cities of Dezful and Borujerd, during the late Qajar and early Pahlavi periods.

Many individuals adopted the surname Varshoochi or Varshabi in Dezful because it was closely associated with their profession as varsho craftsmen.

These institutions have played an integral role in promoting education, research, and professional development in khuzetsan, significantly contributing to Dezful's academic and cultural richness.
