Bojnūrd
Bojnūrd lies in the highland corridor of northeastern Iran, south of the Kopet Dag and east of the Aladagh range. Cold winters, spring streams and dry surrounding plains made the site a useful stopping place between Khorasan, the Caspian approaches and the Turkmen frontier. Settlement depended on wells and irrigation channels rather than on a large river.
After the Mongol invasions, local tradition places the region under Qarai Turkic chiefs. The later town is associated with the Safavid period, when Kurdish Shadiyan groups were settled to guard the frontier. A defensive wall enclosed eleven quarters, bazaars and four mosques. Those institutions made Bojnūrd a small but organized centre for trade, worship and military control.
The town lay within the wider Khorasan economy of grain, livestock, textiles and caravan traffic. Persian officials, Kurdish chiefs and Turkmen raiders competed for influence across the passes and wells. Walls, bazaars and cisterns allowed people to survive siege and drought. Bojnūrd’s identity came from this frontier position, where mountain routes and the need for protection shaped a compact urban centre.
