History of IranThe history of Iran is intertwined with the history of a larger region known as Greater Iran, comprising the area from Anatolia in the west to the Indus river and the Syr Darya in the east, and from the Caucasus and the Eurasian Steppe in the north to the Persian Gulf and the Gulf of Oman in the south. Central to this area is Iran, commonly known until the mid-20th century as Persia in the Western world. Iran is home to one of the world's oldest continuous major civilizations, with historical and urban settlements dating back to 4000 BC.
