Iran, also known as Persia, officially the Islamic Republic of Iran since 1980, is a country in Western Asia. It is bordered on the north by Armenia, Azerbaijan and Turkmenistan, with Kazakhstan and Russia across theCaspian Sea; on the east by Afghanistan and Pakistan; on the south by the Persian Gulf and the Gulf of Oman; on the west by Iraq; and on the northwest byTurkey. Comprising a land area of 1,648,195 km2 (636,372 sq mi), it is the second-largest nation in the Middle East and the 18th-largest in the world; with over 77 million inhabitants, Iran is the world's 17th most populous nation. It is the only country that has both a Caspian Sea and Indian Ocean coastline. Iran has been of geostrategic importance because of its central location in Eurasia and Western Asia and the Strait of Hormuz. Iran is home to one of the world's oldest civilisations, beginning with the formation of the Proto-Elamite and Elamite kingdom in 3200 – 2800 BCE. TheIranian Medes unified the country into the first of many empires in 625 BCE, after which it became the dominant cultural and political power in the region. Iran reached the pinnacle of its power during the Achaemenid Empire (First Persian Empire) founded by Cyrus the Great in 550 BCE, which at its greatest extent comprised major portions of the ancient world, stretching from the Indus Valley in the east, to Thrace and Macedon on the northeastern border of Greece, making it the largest empire the world had yet seen.The empire collapsed in 330 BCE following the conquests of Alexander the Great. The area eventually regained influence under the Parthian Empire and rose to prominence once more after the establishment of the Sasanian dynasty (Neo-Persian empire) in 224 CE, under which Iran became one of the leading powers of Western and Central Asia for the next four centuries.
