In its golden ages, Borujerd was selected as the state capital of Lorestan and Khuzestan region during Qajar dynasty in the 18th and 19th centuries.

The Parthian king Orodes II (r. 57–37 BC) is credited by some academics with laying the city's foundation.

Others consider it to have been built by the Sasanian king Peroz I (r. 459–484), arguing that "Piruzgird" was its original name, before being changed into "Burugird", and then later Arabicised into "Burujird".

[2] Borujerd city is located approximately 1670 meters above sea level and has a moderate climate with cold winters.

The highest point is Garrin Mountain 3623 m above sea level and the lowest area is Gelerood River in South with 1400 m elevation.

Wherever irrigation is possible (by means of qanāts, wells, diversion of water of streams), cotton, melons, grapes, and fruit trees (especially almonds) are grown.

[citation needed] The high-elevated Zagros Mountains surrounds it from South East to North West and the peaks are covered with snow most of the times.

Borujerd's climate is classified as Mediterranean(Köppen: Csa) with dry and very hot summers and cold winters.
