Tehran got appointed as the capital in the time of Agha Mohammad Khan and started growing since then. Mosques and regions were added to this city and the wall around the city grew rapidly and it got to a six kilometer of length. In the time of Mohammad Shah Qajar (the third king of Qajar) a great event happened in the history of Tehran which was the transference of the water of Karaj River to Tehran flowing now in the middle of the present Keshavarz Boulevard. This boulevard is in the center of the city and the famous Espinas Hotel is in front of it. Construction in the urban boundary of this city in Nasereddin Shah’s time was moved beyond the boundary and royal palaces, aristocratic belvederes, embassies and the foreigners’ houses were all built outside the city.

The population of Tehran was then recorded 150 thousand people. The present visage of Tehran is a memorial of the development and advancement in Pahlavi era especially the second Shah of Pahlavi. It was in that time that all the walls and trenches around the city were removed and new buildings and constructions like banks, foreign minister, municipality, railroad, radio station, and several hospitals were added to Tehran. Moreover, the presence of cars in Tehran caused the construction of rather ordered streets. In the second Pahlavi era and after World War II, this development rose up day by day and the country’s population reached 4.350.000 in 1977.

After the establishment of the regime of Islamic Republic in the country, the imposed war between Iran and Iraq took place and this slowed the development of the city down. The avian bombardments of Tehran by Saddam forced many people to migrate outside the city and made the city not to thrive for a while. After the war, technological advancement of the city made Tehran develop to some point. Now the distance from east to west is about 50 kilometers and north to south about 50 kilometers. The interesting point about the population is the inflow of people entering Tehran for work during the day which is about 13 million and is about 8.5 million over night (This census is approximate and was gathered in 2016).
