Karaj (Persian: کرج; pronounced [kæˈɾædʒ] ^ⓘ)^[a] is a city in the Central District of Karaj County, Alborz province, Iran, serving as capital of the province,^[5] the county, and the district.^[6] The earliest records of Karaj date back to the 30th century BC. The city was developed under the rule of the Safavid and Qajar Empire and is home to historical buildings and memorials from those eras. This city has a unique climate due to access to natural resources such as many trees, rivers, and green plains. After Tehran, Karaj is the largest immigrant-friendly city in Iran, so it has been nicknamed "Little Iran."^{[citation needed]}

Although the county hosts a population around 1.97 million, as recorded in the 2016 census,^[3] most of the 1,419 km² (548 sq mi) county is rugged mountain. The urban area is the fourth-largest in Iran, after Tehran, Mashhad, and Isfahan.^[7] Eshtehard County^[8] and Fardis County^[9] were split off from Karaj County since the previous census.

The area around Karaj has been inhabited for thousands of years, as shown by the Bronze Age site of Tepe Khurvin and the Iron Age site of Kalak.^[10][11] However, the present-day city of Karaj is mostly the result of modern industrial development in the 20th century.^[11]

Karaj was mostly significant as a stage on the road between Tehran and Qazvin.^[11] In Safavid times, a stone bridge was built that served as the main crossing into the town.^[11] The large Shah-Abbasi Caravansarai, located at the southeast of Towhid Square, was built in the same era, under the rule of Šāh Esmāil.

In 1810, the Qajar prince Soleyman Mirza built the Soleymaniyeh Palace at Karaj to serve as a summer resort.^[11] The palace had four towers and was surrounded by gardens, and its reception room featured a pair of paintings by Abdallah Khan Naqqashbandi.^[11] By 1860, however, the palace was described as abandoned and only used as a shelter for travelers.^[11] Naser al-Din Shah Qajar later renovated the palace.^[11] In 1917, a School of Farming was established on the site, replacing the earlier Mozaffari Agricultural School in Tehran.^[11] Later, Reza Pahlavi granted it to the University of Tehran's new Faculty of Agriculture.^[11]

In the 1930s, plans were drawn up for a large industrial complex covering 216 hectares on the south side of the village.^[11] This "Industrial Model Town of Karaj" was intended to be the site of the country's first steel mills, capitalizing on easy access to water and coal from the Alborz.^[11] However, the construction equipment imported from Germany was impounded by the British going through the Suez Canal in 1940, and the planned complex was never built.^[11]

A major industrial complex, the first privately-owned one in Karaj, was built in the 1960s by Mohammad-Sadeq Fateh.^[11] This complex, called Shahrak-e Jahanshahr, included oil, tea, and textile factories as well as housing for the workers.^[11]

The Morvārid Palace was constructed in nearby Mehršahr district, during the Pahlavi era. It was designed by the Frank Lloyd Wright Foundation (Taliesin Associated Architects) on instructions from Shams Pahlavi, elder sister of Mohammad Reza Pahlavi. In this period it was a transit and industrial town.

Majority of the structure is now controlled by the Basij Organization, and some sections of it are open to public under the operation of Cultural Heritage Organization of Iran.

Other historical sites of the city include the Mausoleum of Šāhzāde Soleymān, Emāmzāde Rahmān, Emāmzāde Zeyd, and Palang Ābād e Eštehārd.^[12]

The majority of the residents of Karaj are Persians, with Azerbaijanis making up the second major ethno-linguistic group of the city. Kurds, Gilak, Tabari and Lurs include the other ethnicities among the population of Karaj.

At the time of the 2006 National Census, the city's population was 1,377,450 in 385,955 households, when it was in Tehran province.^[15] The 2016 census measured the population of the city as 1,592,492 people in 508,420 households,^[3] by which time the county had been separated from the province in the establishment of Alborz province.^[5]

The downtown of Karaj is usually referred to Karaj Square, located hundred of meters to the west of Karaj River and the old Karaj Bridge. The villages Hesārak, Gowhar Dašt, and Šahrak e Azimie are located in the northern Greater Karaj.

Meškin Dašt, a large agricultural area between Mehršahr and Fardis, is near Karaj.

The following table includes the major districts of the city:

Open space recreational areas of Karaj include Irānzamin Park, Pārk e Xānvāde, Tennis Park, Pārk e Mādar, Tāleqān Gardens, Kordān Gardens, Jahānšahr Gardens, Pardis e Golhā, and the Tulip Garden of Gačsār.

The climate of Karaj is a bit cooler than Tehran's, and it receives 250 mm of rain annually (and like Tehran, the precipitation pattern is similar to those of Mediterranean climates). The Köppen-Geiger climate classification system classifies the city's climate as cold semi-arid (BSk).^[16]

Amir Kabir Dam and some other small lakes are based in Karaj. The city is a starting point for a drive along road forced north through the Alborz mountain to the Caspian Sea.^[23]

Zowb Āhan, the avenue leading to an industrial plant, is located at the south of Ostandar Square. Zowb e Āhan or Zowb Āhan, literally "steel mill", was a contract between the Pahlavi government and a consortium from Nazi Germany. The establishment of the factory Zowb Āhan e Karaj was halted by the beginning of the Second World War, and it was never launched.

Šahrak-e Jahānšahr was the first modern private industrial and housing complex of Karaj, built in the 1960s. The factories Jahān Čit (textile factory), Rowqan Nabāti e Jahān (oil factory), and Čāy e Jahān (tea factory), were established at the complex. It is one of the largest industrial zones of the nation, with a 20% share of the national GDP.

The special economic zone of Payam, with an area about 3,600 ha (36 km²; 8,900 acres) within the territory of Payam International Airport, was established in Karaj for development of air cargo and postal transportation, cold store, and packing services, as well as perishable and time sensitive exports. It is the only SEZ in the region with the privilege of its own airline.

Small and medium women's clothing companies in Karaj produce all kinds of daily clothes and leather boots. Karaj was one of the few Iranian cities in the 2010s that controlled the damage to the environment in the process of producing women's clothing. Karaj women's over-the-knee boots are exported to the whole country and have a significant contribution to the city's economy.^[24]

Bākeri Expressway is one of the main north-to-south routes in west Tehran, which is connected to the Tehran–Karaj Highway.^[27] Tehran–Karaj Highway is one of the busiest sections in Iran with AADT of 217084.^[28] Karaj–Qazvin has an AADT of 79606.

The aerial transport of Karaj is served by the Payam International Airport, which was established in 1990, and was officially opened in 1997.
