The history of Abadan is rooted in the early Middle Ages. Located on a strategically important island in the Shatt al-Arab delta, the city has come a long way from a modest settlement to a major port centre. According to legend, the city was founded in the 8th–9th centuries, and its emergence is linked to an Islamic saint named Abbad, after whom the settlement received its original name. There is also a version that the name comes from the Persian words "ab" (water) and "pa" (guard), which can be translated as "coast guard post," perfectly describing its geographical function.
During the reign of the Abbasid dynasty, Abadan began to develop as a port city, gradually gaining prominence in the region. Its rise was facilitated by its unique geographical position at the confluence of major rivers and in close proximity to the Gulf, making Abadan a natural trading hub. For centuries, the city was a subject of disputes, but in 1847 it definitively became part of Persia (modern Iran), which solidified its status.
In the early period of its history, Abadan was a small but functional port city. Its economy focused on local industries such as salt mining and craft production, particularly the weaving of mats. These facts are confirmed by the notes of the famous traveller Ibn Battuta, who described Abadan as a small town. Its geographical location ensured a constant, though not always large, flow of merchants, fostering cultural exchange and sustaining life in this unique island settlement.
