General Information About Iran

Map and land of Iran

IRAN, officially Islamic Republic of Iran, has the area of 636,290 sq miles (1,648,000 sq km), SW Asia. The country’s name was changed from Persia to Iran in 1935. Iran is bordered on the north by Armenia, Azerbaijan, Turkmenistan, and the Caspian Sea; on the east by Afghanistan and Pakistan; on the south by the Persian Gulf and the Gulf of Oman; and on the west by Turkey and Iraq.

The Shatt al Arab forms part of the Iran-Iraq border. Tehran is the capital, largest city and the political, cultural, commercial, and industrial center of the nation. The country is divided into 30 provinces. In addition to Tehran, important cities include Isfahan, Shiraz, Mashhad, Tabriz, Rasht, Hamadan, Abadan, and Ahwaz.

The land lies within the Alpine-Himalayan mountain system and is composed of a vast central plateau rimmed by mountain ranges and limited lowland regions. Iran is subject to numerous and often severe earthquakes and volcanic eruptions. The Iranian Plateau (alt. 4,000 ft/1,200 m), which extends beyond the low ranges of E Iran into Afghanistan, is a region of interior drainage. It consists of a number of arid basins of salt and sand, such as those of Dasht-e Kavir and Dasht-e Lut, and some marshlands, such as the area around Hamun-i-Helmand along the Afghanistan border. The plateau is surrounded by high folded and volcanic mountain chains including the Kopet Mts. in the northwest, the Elburz Mts. (rising to 18,934 ft/5,771 m at Mt. Damavand, Iran’s highest point) in the north, and the complex Zagros Mts. in the west. Lake Urmia, the country’s largest inland body of water, is in the Zagros of NW Iran. Narrow coastal plains are found along the shores of the Persian Gulf, Gulf of Oman, and the Caspian Sea; at the head of the Persian Gulf is the Iranian section of the Mesopotamian lowlands. Of the few perennial rivers in Iran, only the Karun in the west is navigable for large craft; other major rivers are the Karkheh and the Sefid Rud.
