History
According to local tradition, the whole area was controlled by the Qarai Turks since the Mongol invasion in the 13th century.
Bojnurd is of recent origin and possibly built by the Safavids for the Kurdish Şadiyan tribe who had been settled there to strengthen the Safavid borders against hostile Turkmens. Traditionally, the city was surrounded by a defensive wall and consisted of eleven quarters, bazaars and four mosques.
In 1849, the city saw a revolt which destroyed the city. When traveller G. C. Napier visited the city in 1876, it was noted that the chief of Bojnurd was a Kurd who governed the city without taxation in exchange for military support to the central government in Tehran.
Severe earthquakes in 1896 and 1929 destroyed the city and its surroundings. The city would consequently be rebuilt without historical or recent fortifications in a modern matter. In 1997, a magnitude 6.5 earthquake caused significant damage and many fatalities in the city.
