Tehran vs Chelyabinsk

Informations

Tehran (; Persian: تهران‎ Ťehrân [tehˈɾɒːn] (listen)) is the capital of Iran and Tehran Province. With a population of around 8.7 million in the city and 15 million in the larger metropolitan area of Greater Tehran, Tehran is the most populous city in Iran and Western Asia, and has the second-largest metropolitan area in the Middle East (after Cairo). It is ranked 24th in the world by the population of its metropolitan area.In the Classical era, part of the territory of present-day Tehran was occupied by Rhages, a prominent Median city. It was subject to destruction through the medieval Arab, Turkic, and Mongol invasions. Its modern-day inheritor remains as an urban area absorbed into the metropolitan area of Greater Tehran. Tehran was first chosen as the capital of Iran by Agha Mohammad Khan of the Qajar dynasty in 1786, 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-Iranian Wars, and to avoid the vying factions of the previously ruling Iranian dynasties. The capital has been moved several times throughout history, and Tehran is the 32nd national capital of Persia. Large-scale demolition and rebuilding began in the 1920s, and Tehran has been a destination for mass migrations from all over Iran since the 20th century.Tehran is home to many historical collections, including the royal complexes of Golestan, Sa'dabad, and Niavaran, where the two last dynasties of the former Imperial State of Iran were seated.

Tehran's most famous landmarks include the Azadi Tower, a memorial built under the reign of Mohammad Reza Shah of the Pahlavi dynasty in 1971 to mark the 2,500th year of the foundation of the Imperial State of Iran, and the Milad Tower, the world's sixth-tallest self-supporting tower which was completed in 2007. The Tabiat Bridge, a newly built landmark, was completed in 2014.The majority of the population of Tehran are Persian-speaking people, and roughly 99% of the population understand and speak Persian, but there are large populations of other ethno-linguistic groups who live in Tehran and speak Persian as a second language.Tehran has an international airport (Imam Khomeini Airport), a domestic airport (Mehrabad Airport), a central railway station, the rapid transit system of Tehran Metro, a bus rapid transit system, trolleybuses, and a large 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 life. According to the Global Destinations Cities Index in 2016, Tehran is among the top ten fastest growing destinations.October 6 is marked as Tehran Day based on a 2016 decision by members of the City Council, celebrating the day when the city was officially chosen as the capital of Iran by the Qajar dynasty back in 1907.

It is the seventh-largest city in Russia by population, with 1,130,132 inhabitants as of the 2010 Census, and the second largest city in the Ural Federal District, after Yekaterinburg. Located in the northeast of the oblast, 210 kilometers (130 mi) south of Yekaterinburg, the city is just to the east of the Ural Mountains. It sits on the Miass River, part of the border between Europe and Asia.The area of Chelyabinsk contained the ancient settlement of Arkaim, which belonged to the Sintashta culture. In 1736, a fortress by the name of Chelyaba was founded on the site of a Bashkir village. Chelyabinsk was granted town status by 1787. Chelyabinsk began to grow rapidly by the late 20th century as a result of the construction of railway links to European Russia and Siberia, including the Trans-Siberian Railway.

Its population reached 70,000 by 1917. Under the Soviet Union, Chelyabinsk became a major industrial centre during the 1930s. The Chelyabinsk Tractor Plant was built in 1933. During World War II, the city was a major contributor to the manufacture of tanks and ammunition. Chelyabinsk remains an important industrial centre, especially heavy industries such as metallurgy and military production. It is home to several educational institutions, mainly South Ural State University and Chelyabinsk State University. In 2013, the Chelyabinsk meteor exploded over the Ural Mountains, with fragments falling into and near the city. The blast of the explosion caused many hundreds of injuries, some of them serious, mostly caused by glass fragments from shattered windows. The Chelyabinsk Regional Museum contains fragments of the meteorite.
