The oldest known empire in Iran was that of the Elamites, B.C. It is the empire they founded between 1100-600. The Medes replaced the Elamites, and their state was destroyed by the Persians. Greeks B.C. They captured all Iranian lands in 330. After this, the sovereignty of the Parthians and Sassanids continued in Iranian lands. The collapse of the Sassanids occurred when the Islamic armies captured Iran. The Islamic armies that entered Iran in droves conquered Azerbaijan, Tabaristan, Curcan, Ray, Kumis, Karvin, Zanjan, Hamadan, Isfahan and Khorasan. Following this, Shah Ismail established the Safavid Dynasty in Iran. Then the Afshar and then the Qajar Dynasty dominated Iran. For a long time, there were wars between the Ottoman Empire and Russia over Iranian domination, but no external power was able to dominate all of Iran for a long time. The period between 1925 and 1979 is the period when the Pahlavi dynasty was on the throne of Iran. In 1963, the Shah of Iran carried out large-scale economic and social reforms in the country under the name “White Revolution”. Increasing oil revenues and especially large expenditures for the country’s defense have started to bring Iran among the countries that have a say in the Middle East, especially in terms of military. At this time, the Iranian Shiite leader Khomeini, who was in exile in France, took advantage of the dominance of the Shiite faith in the country and gathered the Shiites in the country around him with the implicit support of Western powers who feared the effects of the economic reform in Iran. As a result of many internal and external struggles, Khomeini came to dominate Iran. The Shah family left Iran and the country began to be governed by the mullah regime.
