Lorestan province (Persian: استان لرستان) is one of the 31 provinces of Iran. Its capital is the city of Khorramabad.
Lorestan is in the western part of the country in the Zagros Mountains and covers an area of 28,392 km. In 2014 it was placed in Region 4.
Bakhtiari dialect is a dialect of the Luri language spoken by Bakhtiari people in Chaharmahal-o-Bakhtiari, Bushehr, eastern Khuzestan and parts of Isfahan and Lorestan provinces. It is closely related to the Boir-Ahamadi, Kohgiluyeh, and Mamasani dialects in northwestern Fars. These dialects, together with the Luri dialects of Lorestan (e.g. Khorramabadi dialect), are referred to as the "Perside" southern Zagros group, or Lori dialects. Luri and Bakhtiari are much more closely related to Persian than Kurdish. Dialects of Persian spoken in Chaharmahal and Bakhtiari province are mutually intelligible with Bakhtiari.
Western Iran consists of Armenian Highlands, northern Zagros, and the rich agricultural area of the Khuzestan Plain in the south.
It includes the provinces of Kordestan, Kermanshah, Ilam, Lorestan, and Hamadan. Some references also count West Azerbaijan Province and Khuzestan Province to this region.
The Bakhtiari (also spelled Bakhtiyari; Persian:بختیاری) are a Lur tribe from Iran. They speak the Bakhtiari dialect of the Luri language.
Bakhtiaris primarily inhabit Chaharmahal and Bakhtiari and eastern Khuzestan, Lorestan, Bushehr, and Isfahan provinces. Bakhtiari tribes have an especially large population concentration in the cities of Masjed Soleyman, Izeh, Shahr-e Kord, and Andika, and the surrounding villages.
