History of Iran
History of Iran is the account of the peoples, states, and cultures of the Iranian plateau, from ancient civilizations to the modern Islamic Republic.
Elam: An ancient civilization in southwestern Iran, centered on Susa, that flourished from the third millennium BCE. Elam’s cities and institutions predate the Persian empires and form part of Iran’s earliest recorded past.
Arab conquest of Iran: The seventh-century Muslim conquest that ended Sasanian rule and brought Iran into the expanding caliphate. It transformed Iran’s political authority and began a gradual religious and cultural transition.
Cyrus the Great: The sixth-century BCE founder of the Achaemenid Empire, known for conquering Babylon and establishing a vast imperial realm. His conquests founded the empire that anchors many accounts of ancient Iran.
Persian language: An Iranian language spoken in Iran and neighboring regions, with a literary tradition spanning more than a millennium. Persian connected successive dynasties and communities across major political transformations.
Ottoman Empire: A multiethnic empire that ruled much of southeastern Europe, western Asia, and North Africa from the fourteenth to early twentieth centuries. Ottoman-Iranian rivalry shaped borders, diplomacy, and sectarian politics for centuries.
Median Empire: An ancient Iranian kingdom that dominated parts of western Iran before the rise of the Achaemenids. The Medes helped establish the political landscape inherited by the first Persian empire.
Iranian Intermezzo: A period when Iranian dynasties gained regional power within the wider Islamic world, especially from the ninth to eleventh centuries. Local dynasties revived Iranian political traditions under caliphal-era institutions.
Darius the Great: An Achaemenid king who expanded the empire and organized its administration in the late sixth and early fifth centuries BCE. His reforms strengthened the imperial machinery that made Achaemenid rule durable.
Twelver Shia Islam: The largest branch of Shia Islam, recognizing twelve divinely designated Imams as spiritual and political successors to Muhammad. Safavid adoption made Twelver Shiism a central marker of Iran’s religious and political identity.
Mughal Empire: A South Asian empire founded in 1526 by Babur and ruled by a dynasty of Central Asian origin. Persianate culture spread into Mughal South Asia, offering a contrast to Iran’s own state trajectory.
