📜 History & Origins
Archaeological evidence shows human settlement near Tehran dating to 6000 BCE. The area was known as a small village during the Safavid period. Tehran became the capital of Iran in 1786 when Agha Mohammad Khan Qajar chose it as his seat of power. The city grew rapidly in the 19th and 20th centuries, particularly under the Pahlavi dynasty. The 1979 Islamic Revolution transformed both the city and the country, and the Iran–Iraq War (1980–88) deepened its political significance as the hub of a nation under pressure.
