Recent archaeological studies indicate that as early as 10,000 BC, people lived on the southern shores of the Caspian, one of the few regions of the world which according to scientists escaped the Ice Age. They were probably the first men in the history of mankind to engage in agriculture and animal husbandry.
The first country known as Iran was founded by Achaemenians, by unifying different tribes living there. Though the history of Iran is long and complex, its shape is determined by the rise and fall of successive dynasties - with intervals of chaos and confusion. The Persian Empire (founded by Cyrus the Great in 6th BC), the Macedonians, Parthians, the Sassanids, the Arabs, the Seljuks and Mongols, the Timurids and the Safavids, all held sway here at one time or another.
After the Arab conquest in the middle of the 7th century, the ancient Persian religion of Zoroastrianism gave way to Islam. Persia continued to be overrun by foreign powers for another thousand years.
The Turkish Safavids belonged to a Sufi religious order and made Shiite Islam the official religion of Iran, undertaking a major conversion campaign of Iranian Muslims. The Safavid dynasty reached its height during the reign of Shah Abbas 1st (1587-I629). It was during his reign that Persia once again came to be known in Europe as a superpower, because it was the greatest opponent of the Ottomans, and their wars saved Europe, the Ottomans being too occupied on the east fighting Iran to make headway in the west.
In 18th-19th centuries Iran fall under the increasing pressure of European nations, particularly the Russian Empire and the Great Britain. The discovery of oil in early 1900s intensified the rivalry of the Great Britain and Russia for power over the nation. After the World War 1st Iran was admitted to the League of Nations as an original member.
In 1921 Reza Khan, an army officer, established a military dictatorship. He was subsequently elected hereditary Shah, thus ending the Qajar dynasty and founding the new Pahlavi dynasty.
In 1979 Iran's most important religious nation-wide uprising led by Ayatollah Khomeini, took place in protest to the so-called White Revolution. After the victory of the Islamic Revolution the same year, the shah was overthrown and Iran, officially renamed the Islamic Republic of Iran, became a theocratic state. The Constitution of 1979 designated Ayatollah Khomeini as the pious jurist or faqih (the policy guide and ultimate decision-maker). April 1, 1979 became the Islamic Republic Day.
