Khomeyni Shahr (, also Romanized as Khomeynī Shahr and Khomeynīshahr; from the 1930s until 1979, known as Homāyūnshahr or Homayoon Shahr (); known as Sedeh (, literally "three villages") prior to the 1930s) is a city in the Central District of Khomeyni Shahr County, Isfahan province, Iran, and serves as both capital of the county and of the district. Khomeyni Shahr is now part of the Isfahan Metropolitan area.

At the 2006 National Census, its population was 218,737 in 57,551 households. The following census in 2011 counted 244,696 people in 70,121 households. The latest census in 2016 showed a population of 247,128 people in 75,180 households.

The town was originally known as Sedeh. In the 1930s, the name was changed to Homayunshahr. After the Iranian Revolution of 1979, the city was renamed again to Khomeyni Shahr (meaning "City of Khomeyni"), in honor of Ayatollah Khomeini. Locals have continued to refer to the city as Sedeh. There has been an ongoing effort to rename back the city's name to its historical one Mehrbin ().

History 
It is commonly believed that the original name, Sedeh (Persian: ), is derived from Se-dezh, meaning "three castles" in Persian, ("dezh" () means "castle"), and is linked to the formation of the town by the growth of three neighbouring castles. The three main castles of Kohan Dedge, Gar Dedge, and .... Dedge (locally pronounced kohan dedge, gar dar and ...).

It is commonly believed that Se-dezh was a Sassanian military base and an old fireplace (atash gah) based on top of the mountain near the town.

The three main villages of Khouzan (locally pronounced Khizoon), Foroushan (the origin of Foroushan was Parishan (pari (angel) + voshan (face))), and Varnosfaderan (Venesfohoon) remain identifiable parts of the city. However, there are in fact five former villages forming identifiable parts of the town. This has led to the argument that the name may be linked to the ancient Persian festival of Sadeh.

The name change to Homayunshahr took place during the reign of Reza Shah Pahlavi. The name literally means "auspicious or august city", but Homayun was also a title of the Shah and so the name was seen as being linked with the Pahlavi dynasty. Thus, after the revolution of 1979, the city was renamed again, this time to be called after Ayatollah Khomeini, the leader of the revolution.

Khomeyni Shahr in antiquity 
Many of the historical events of Khomeini Shahr are influenced by the events that took place in Isfahan. However, the historical antiquity of this region dates back to the Sassanid era, the ancient fortress which is located on the way to Isfahan, seems to have been the capital of the Sassanids. In the Islamic era, this area was also very important, and the existence of a large Grand Mosque in Khozan Alley shows that it was a city in the past. Because the Grand Mosque is an urban feature and the villages do not have it. In Mohammad Afghan's invasion of Isfahan, the people of the century bravely persevered and captured a large number of Mahmoud's troops.

The distance between the city and Isfahan is 8 km. Khomeini Shahr city is located in the west of Isfahan province and is limited to Borkhar and Maymeh cities in the north, Falavarjan city in the south, Isfahan city in the east and Najafabad city in the west. This city is one of the most pleasant and most prosperous areas of Isfahan province. Its soil is irrigated by the Zayandehrud River and all its streams are full of water. In addition, it has important caries, which has caused three-quarters of the city's soil to be large orchards and a quarter of its fields.

The material of "Qomish" passes through the southern lands of the city, and because it is connected to the springs at the point of separation from the river, its water never runs out.

Fruits and ground products such as wheat, barley, cucumbers, melons, legumes, tobacco are grown in the city, and some varieties such as spring melons, pavilions, grapes, cherries, Nasrabad and Gortan are famous and similar in other places. Not found.

Its climate is temperate and dry. The highest temperature in summer is 39 degrees above zero and the lowest in winter is 8 degrees below zero.

Since Khomeini Shahr was formed from three dozen names called Khozan, Forosh and Vernosfadran, it was called (three ten) which was gradually renamed Homayounshahr and then Khomeyni Shahr due to the expansion of these villages and their connection to each other.
