Tehran vs Canoas

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.

Canoas (Portuguese pronunciation: [kaˈnoɐs]), which earned city status in 1939, is a municipality in the Brazilian state of Rio Grande do Sul. With more than 340,000 inhabitants, it is part of the Porto Alegre conurbation and has the second highest GDP in the state. It is also the fourth largest city in the state by population. Canoas boasts a strong manufacturing-based economy and is the home of the Canoas Air Force Base, used by the Brazilian Air Force. According to the IBGE, Brazil's Geography and Statistics Institute, Canoas currently has no rural areas, but it started as a village of large landowners. The first of them was conquistador Francisco Pinto Bandeira, who received from the Portuguese Crown, in 1740, an area north of the Gravataí River. History has that 1871 was the beginning of the village of Canoas, when the first section of the railway that would link Porto Alegre to São Leopoldo was inaugurated.

Canoas was then part of the municipalities of Gravataí and São Sebastião do Caí. Soon large farms would lose space to small properties. After obtaining city status, Canoas experienced rapid growth, especially after 1945. At that time, it would be called a "cidade-dormitório" (Portuguese for "bedroom city"), because thousands of people would commute to neighboring Porto Alegre to work. However, de-industrialisation in Porto Alegre, the setting-up of numerous manufacturing plants in Canoas and a strong demographic growth have reverted that situation and nowadays Canoas has a per capita GDP higher than Porto Alegre.
