What is "tehran"

also Teheran, Iranian capital, said to mean "flat, level, lower," but sometimes derived from Old Persian teh "warm" + ran "place."

Tehran ( – Tehrān, ) is the capital of Iran and Tehran Province. With a population of around 9 million in the city and 16 million in the wider metropolitan area, Tehran is the largest city and urban area of Iran, the 2nd-largest city in Western Asia, and the 3rd-largest in the Middle East. It is ranked 29th in the world by the population of its metropolitan area.

In the Classical era, part of the present-day city of Tehran was occupied by a Median city which in the Avesta occurs as Rhaga. It was destroyed by the Mongols in the early 13th century, and remains now as a city in Tehran Province, located towards the southern end of the modern-day city of Tehran.

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, before being separated from Iran as a result of the Russo-Persian Wars, and to avoid the vying factions of the previously ruling 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 Iran. It is home to many historical collections, such as the royal complexes of Golestan, Sa'dabad, 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.

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. Tabiat Bridge, which was completed in 2014, is considered the third symbol of the city.

The majority of the people of Tehran are Persian-speaking people, 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 their second language.

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. A 2016 survey of 230 cities by consultant Mercer ranked Tehran 203rd for quality of living.

Tehran (1941–1966) was a British Thoroughbred racehorse and sire, who raced during World War II and was best known for winning the classic St Leger in 1944. After showing little ability as a two-year-old he improved in the following spring to win the Culford Stakes on his three-year-old debut. He ran third in the 2000 Guineas and was narrowly beaten into second place in the Derby Stakes. After winning the Whepstead Stakes he recorded his biggest win when defeating a strong field in a substitute St Leger. He won his first three races in 1945 and finished second in the Ascot Gold Cup. He later became a successful breeding stallion, siring several major winners including Tulyar.
