A "Jiroft culture" has been postulated as an early Bronze Age (late 3rd millennium BC) archaeological culture, located in the territory of present-day Sistan and Kermān Provinces of Iran. The hypothesis is based on a collection of artifacts that were confiscated in Iran and accepted by many to have derived from the Jiroft area in south central Iran, reported by online Iranian news services, beginning in 2001.
The proposed type site is Konar Sandal, near Jiroft in the Halil River area. Other significant sites associated with the culture include; Shahr-e Sukhteh (Burnt City), Tepe Bampur, Espiedej, Shahdad, Tal-i-Iblis and Tepe Yahya.
The proposition of grouping these sites as an "independent Bronze Age civilization with its own architecture and language", intermediate between Elam to the west and the Indus Valley Civilization to the east, is due to Yusef Majidzadeh, head of the archaeological excavation team in Jiroft. He speculates they may be the remains of the lost Aratta Kingdom, but his conclusions have met with skepticism from some reviewers. Other conjectures (e.g. Daniel T. Potts, Piotr Steinkeller) have connected the Konar Sandal with the obscure city-state of Marhashi, that apparently lay to the east of Elam proper.
Many artifacts associated with Jiroft were recovered from looters described as "destitute villagers" who had scavenged the area south of Jiroft before 2001, when a team led by Yusef Majidzadeh began excavations. The team uncovered more than two square kilometers of remains from a city dating back to at least the late 3rd millennium BC. The data Madjidzadeh's team has gathered demonstrates that Jiroft's heyday was from 2500 B.C. to 2200 B.C.
