Fars territory or Ancient Persia (Persian: سرزمین فارس یا پارس کهن, in Old Persian: 𐎱𐎠𐎼𐎿 (Pārsa)) in the southern part of Iran leading to the Persian Gulf, which has historical, continental, cultural and especially dialectal commonalities and includes the provinces of Khuzestan, Fars, Esfahan, Bushehr, Kohgiluyeh and Boyer-Ahmad, Hormozgan and Chaharmahal and Bakhtiari and the western part of Kerman Province, which is known as the origin of Persian language and inherited from Middle Persian. Which is still culturally and linguistically distinct to this day.
In 558 BC, Cyrus the Great (Cyrus II) was born in Anshan (Persia), somewhere between the cities Izeh in the northeast of Khuzestan and the southwest of Chaharmahal and Bakhtiari. The Cyrus the Great founded Satrap of Persia (in place of present-day Marvdasht, north of Fars Province), then he moved Achaemenid Empire capital to Susa.
One of the most important commonalities of the Fars territory is language and dialect. This region is the origin of Persian language and in addition to that, the forms of the old Pahlavi dialect have remained in it until today. Pahlavi dialects still retain the Middle Persian dialect. Their most important feature is having a metaphorical and ergative split mode, and like the Sassanid Pahlavi verb, the morphological identities are still placed before the verb. Apart from this, there is no other special difference with Persian. These dialects are common in Fars province, Dashti region in Bushehr Province and Behbahan in Khuzestan and a few villages in Kohgiluyeh and Boyer-Ahmad and Hormozgan except in the east of the province where Balochi language is used. Most of the users of Pahlavi dialects in Fars province live in the villages of Koohmareh in Arzhan District, and Dashtak of Marvdasht and the villages around Kazerun and Bishapur and Larestan County. The old Shiraz dialect, to which Hafez and Saadi have poems, is also of the same dialect, which, like Persian, is a remnant of the South Pahlavi language.
