Irahistan
Irahistan or Irahestan is a historical region consisting of southern Fars Province and western Hormozgan Province in Iran.
The region of Irahistan currently consists of several counties in Fars province and Bastak County, Bandar Lengeh County and Parsian County in Hormozgan. The region's importance grew during the Sassanid period with vast expansion of settlements in Irahistan.
In medieval times, the region was ruled by local lords until they were removed by a Safavid invasion in 1610. In the thirteenth century, the city of Lar became a center of trade and commerce in Irahistan and the population of this city grew rapidly, outpacing the more historical towns and cities. The people in this region speak Persian and Achomi.
