Tehran was first chosen as the capital of Iran by Agha Mohammad Khan of the Qajar dynasty in 1796, in order to remain within close reach of Iran's territories in the Caucasus, at that time still part of Iran, and to avoid the vying factions of previous Iranian dynasties. The capital has been moved several times throughout the history, and Tehran is the 32nd national capital of Iran.

The city was the seat of the Qajars and Pahlavis, the two last imperial dynasties of the country. It is home to many historical collections, such as the royal complexes of Golestan, Saadabad, and Niavaran, as well as the country's most important governmental buildings of the modern period.

Large scale demolition and rebuilding began in the 1920s, and Tehran has been a destination for the mass migrations from all over Iran since the 20th century.[8]

The most famous landmarks of the city include the Azadi Tower, a memorial built during the Pahlavi period, and the Milad Tower, the world's 17th tallest freestanding structure which was built in 2007. The Tabiat Bridge is considered the third symbol of the city and it was built in 2014.[9]

The majority of the people of Tehran are Persian-speaking people who identify themselves as Persians,[10][11] and roughly 99% of the population understand and speak Persian; but there are also large populations of other Iranian ethnicities in the city such as Azerbaijanis, Armenians, Lurs, and Kurds who speak Persian as of their second language.[12]

Tehran is served by the Mehrabad and Khomeini international airports, a central railway station, the rapid transit rail system of the Tehran Metro, as well as a trolleybus and a BRT system, and has a huge network of highways.

There have been plans to relocate Iran's capital from Tehran to another area; due mainly to air pollution and the city's exposure to earthquakes. To date no definitive plans have been approved.
