Iran ( Persian : ایران Irān [ ʔiːˈɾɒːn ] ( listen ) ) , also called Persia , and officially the Islamic Republic of Iran ( Persian : جمهوری اسلامی ایران Jomhuri-ye Eslāmi-ye Irān ( listen ) [ dʒomhuːˌɾije eslɒːˌmije ʔiːˈɾɒn ] ) , is a country in Western Asia . With 82 million inhabitants , Iran is the world 's 18th most populous country . Its territory spans 1,648,195 km2 ( 636,372 sq mi ) , making it the second largest country in the Middle East and the 17th largest in the world . Iran is bordered to the northwest by Armenia and the Republic of Azerbaijan , [ a ] to the north by the Caspian Sea , to the northeast by Turkmenistan , to the east by Afghanistan and Pakistan , to the south by the Persian Gulf and the Gulf of Oman , and to the west by Turkey and Iraq . Its central location in Eurasia and Western Asia , and its proximity to the Strait of Hormuz , give it geostrategic importance . Tehran is the political and economic center of Iran , and the largest and most populous city in Western Asia with more than 8.8 million residents in the city and 15 million in the larger metropolitan area . Iran is home to one of the world 's oldest civilizations , beginning with the formation of the Elamite kingdoms in the fourth millennium BCE . It was first unified by the Iranian Medes in the seventh century BCE , and reached its territorial height in the sixth century BCE under Cyrus the Great , whose Achaemenid Empire stretched from Eastern Europe to the Indus Valley , one of the largest empires in history . The empire fell to Alexander the Great in the fourth century BCE and was divided into several Hellenistic states . An Iranian rebellion established the Parthian Empire in the third century BCE , which was succeeded in the third century CE by the Sasanian Empire , a leading world power for the next four centuries . Arab Muslims conquered the empire in the seventh century CE , and the subsequent Islamization of Iran led to the decline of the once dominant Zoroastrian religion . Iran 's major contributions to art , philosophy , and science spread throughout the Muslim world and beyond during the Islamic Golden Age .
Tehran or Teheran ( /tɛəˈræn , -ˈrɑːn , ˌteɪə-/ ; Persian : تهران Ťehrân [ tehˈɾɒːn ] ( listen ) ) is the capital of Iran and Tehran Province . With a population of around 8.7 million in the city and 15 million in the larger metropolitan area of Greater Tehran , Tehran is the most populous city in Iran and Western Asia , and has the second-largest metropolitan area in the Middle East ( after Cairo ) . It is ranked 24th in the world by the population of its metropolitan area . In the Classical era , part of the territory of present-day Tehran was occupied by Rhages , a prominent Median city . It was subject to destruction through the medieval Arab , Turkic , and Mongol invasions . Its modern-day inheritor remains as an urban area absorbed into the metropolitan area of Greater Tehran . Tehran was first chosen as the capital of Iran by Agha Mohammad Khan of the Qajar dynasty in 1786 , in order to remain within close reach of Iran 's territories in the Caucasus , before being separated from Iran as a result of the Russo-Iranian Wars , and to avoid the vying factions of the previously ruling Iranian dynasties . The capital has been moved several times throughout history , and Tehran is the 32nd national capital of Iran . Large-scale demolition and rebuilding began in the 1920s , and Tehran has been a destination for mass migrations from all over Iran since the 20th century . Tehran is home to many historical collections , including the royal complexes of Golestan , Sa'dabad , and Niavaran , where the two last dynasties of the former Imperial State of Iran were seated . Tehran 's most famous landmarks include the Azadi Tower , a memorial built under the reign of Mohammad Reza Shah of the Pahlavi dynasty in 1971 to mark the 2,500th year of the foundation of the Imperial State of Iran , and the Milad Tower , the world 's sixth-tallest self-supporting tower which was completed in 2007 . The Tabiat Bridge , a newly built landmark , was completed in 2014 .

Hellenization started during the era of Alexander the Great and continued into the Byzantine era . The Seljuk Turks began migrating into the area in the 11th century , and their victory over the Byzantines at the Battle of Manzikert in 1071 symbolises the start and foundation of Turkey . The Seljuk Sultanate of Rûm ruled Anatolia until the Mongol invasion in 1243 , when it disintegrated into small principalities called beyliks . Beginning in the late 13th century , the Ottomans started uniting beyliks and conquering the Balkans . After Mehmed II conquered Constantinople in 1453 , Ottoman expansion continued under Selim I . During the reign of Suleiman the Magnificent the Ottoman Empire encompassed much of Southeast Europe , West Asia and North Africa and became a world power .

Founded under the name of Byzantion ( Βυζάντιον ) on the Sarayburnu promontory around 660 BCE , the city grew in size and influence , becoming one of the most important cities in history . After its reestablishment as Constantinople in 330 CE , it served as an imperial capital for almost 16 centuries , during the Roman/Byzantine ( 330-1204 ) , Latin ( 1204-1261 ) , Palaiologos Byzantine ( 1261-1453 ) and Ottoman ( 1453-1922 ) empires . It was instrumental in the advancement of Christianity during Roman and Byzantine times , before the Ottomans conquered the city in 1453 CE and transformed it into an Islamic stronghold and the seat of the Ottoman Caliphate . Under the name Constantinople it was the Ottoman capital until 1923 . The capital was then moved to Ankara and the city was renamed Istanbul .
