Tehran is the capital of Iran as well as the capital of the Tehran province. Tehran is the biggest city and urban region in Iran, the second largest in Western Asia, and the third largest in the Middle East, with a population of roughly 9 million in the city and 16 million in the greater metropolitan area. It is rated 29th in the globe in terms of metropolitan population.
Agha Mohammad Khan Qajar Dynasty selected Tehran as the primary capital of Iran in 1796 in order to stay within the reach of the Iranian provinces of the Caucasus, which are now part of Iran, and to escape the vindicating groups of the past Iranian kings. The capital has been relocated multiple times throughout history, and Tehran is now Iran’s 32nd national capital.
The city was the capital of the country’s last two imperial dynasties, the Qajars and the Pahlavis. It is home to several historical treasures, including the royal complexes of Golestan, Sa’dabad, and Niavaran, as well as the country’s most prominent government buildings during the contemporary time.
The majority of Tehran’s population is made up of Persian-speaking people who identify as Persians, and approximately 99 percent of the population understands and speaks Persian; however, there are large populations of other Iranian ethnic groups in the city, including Azerbaijan, Armenian, Kurdish, and Kurdish who speak Persian as a second language.
There are proposals to relocate Iran’s capital from Tehran to another location, mostly owing to air pollution and the city’s vulnerability to earthquakes. No final proposal has been authorized as of yet.
