Markazi province was part of theMedian Empire in the first millennium BC, which included all of the central and western parts of modern-dayIran. The region is considered to be one of the ancient settlements on theIranian plateau. Numerous remaining ruins testify to the antiquity of this area.
In the early centuries of Islam, the name of the area was changed toJibal orKuhestan. By the early 10th century,Khorheh had become a famous city of Jibal province, followed byTafresh andKhomein.
In recent times, the expansion of the north–south railroad (commonly known as thePersian Corridor) and the establishment of major industries have helped boost development in the area.
