Tehran (Persian: تهران Tehrān, ) is the capital and largest city of Iran, and the administrative center of Tehran Province. Tehran is a sprawling city at the foot of the Alborz mountain range with an immense network of highways unparalleled in Western Asia. Tehran is famous for its numerous ski resorts on the Alborz slopes, large museums, art centers, and palace complexes. Tehran is the second largest city in the Middle East and is the second most populated city in South Western Asia with a population of 7,404,515 and approximately 15 million in Greater Tehran.

Most Iranian industries are headquartered in Tehran. The industries include the manufacturing of automobiles, electrical equipment, military weaponry, textiles, sugar, cement, and chemical products. It is also a leading center for the sale of carpets and furniture. There is also an oil refinery located in south of the city.

In the 20th century, Tehran faced a large migration of people from all around Iran. Today, the city contains various religious minorities, and has many historic mosques, churches, synagogues and Zoroastrian fire temples.

History

Don Ruy Gonzáles de Clavijo, a Castilian ambassador, was probably the first European to visit Tehran, stopping in July 1404, while on a journey to Samarkand (now in Uzbekistan) and the Mongol capital at the time. At this time, the city of Tehran was unwalled.

Tehran became a residence of the Safavid rulers in the 17th century. Tahmasp I built a bazaar and a wall around the city, but it somewhat fell out of favor after Abbas I turned sick when he was passing the city to go to a war with the Uzbeks.

In the early of 18th century, Karim Khan Zand ordered a palace, a haremFact: date=June 2007, and a government office to be built in Tehran, possibly to declare the city his capital, but later moved his government to Shiraz. Tehran finally became the capital of Iran in 1795, when the Qajar king Agha Mohammad Khan was crowned in the city. It remains the capital to this day.

During World War II, British and Soviet troops entered the city. Tehran was the site of the Tehran Conference in 1943, attended by U.S. President Franklin D. Roosevelt, British Prime Minister Winston Churchill, and Soviet Premier Joseph Stalin.

Following the war, the city's older landmarks suffered under the rule of Mohammad Reza Shah. The Shah believed that ancient buildings such as large parts of the Golestan Palace, Takieh-ye Dowlat, the Toopkhaneh Square (pictured to the right), the magnificent city fortifications and the old citadel among others should not be part of a modern city. They were systematically destroyed and modern 1950s and 1960s buildings were built in their place. Tehran bazar was divided in half and many historic buildings were destroyed in order to build wide straight avenues in the capital. Many excellent examples of Persian Gardens also became targets to new construction projects. The decision to carry these out is presently largely seen as a foolish mistake that hurt the visual fabric and the cultural identity of the city beyond repair. Apartment blocks are introduced in this period.
