As

180-747: A group of Tamim had been living since pre-Islamic times. However, following the fall of the Abbasid dynasty, the flow of Arab immigrants into Persia gradually diminished, but it nonetheless continued. In the latter part of the 16th century, the Bani Kaab (pronounced Chaub in the local Gulf dialect), from Kuwait , settled in Khuzestan. And during the succeeding centuries, more Arab tribes moved from southern Iraq to Khuzestan. According to C.E. Bosworth in Encyclopædia Iranica , under

240-538: A non-Persian Bakhtiari minority, while the southern section always had diverse minority groups known as Khuzis. Since the 1940s, a flood of job seekers from all over Iran to the oil and commerce centers on the Persian Gulf Coast has made the region more Persian-speaking. Presently, Khuzestan still maintains its diverse group, but does have Arabs, Persians, Bakhtiari and ethnic Qashqais and Lors. Khuzestan has great potential for agricultural expansion , which

300-542: A non-Semitic, and non-Indo-European-speaking kingdom, and "the earliest civilization of Persia" . The name Khuzestan is derived from the Elamite ( ʰŪvja ), likely pronounced /xuʒa/, later Middle Persian Hūzīg , Arabic al-Xūzīya . In fact, in the words of Elton L. Daniel , the Elamites were "the founders of the first 'Iranian' empire in the geographic sense." Hence the central geopolitical significance of Khuzestan,

360-509: A politically sensitive region, particularly given its history of foreign intervention, notably the Iraqi invasion of 1980. Some ethnic groups complain over the distribution of the revenue generated by oil resources with claims that the central government is failing to invest profits from the oil industry in employment generation, post-war reconstruction and welfare projects. Low human development indicators among local Khuzestanis are contrasted with

420-812: A third of the spoil. The Basrans purged the Nestorians—the Exegete of the city and the Bishop of Hormizd, and all their students—but kept Hormuzan alive. There followed the conquests of Gundeshapur and of many other districts along the Tigris. The Battle of Nahāvand finally secured Khuzestan for the Muslim armies. During the Muslim conquest the Sassanids were allied with non-Muslim Arab tribes, which implies that those wars were religious, rather than national. For instance in 633–634, Khaled ibn Walid leader of

480-505: Is Lur . During a research that was commissioned by the General Culture Council in 2010 and based on a field survey and a statistical community among the residents of 288 cities and about 1400 villages across the country, the percentage of ethnic groups that were sampled in this survey in this province was as follows.

Its author was his court historian and scribe Iskandar Beg Munshi , who completed it in 1629. The book is considered the most significant piece of Iranian historiography written about the Safavids. It has greatly influenced Safavid studies and serves as the foundation for

600-482: Is almost unrivaled by the country's other provinces. Large and permanent rivers flow over the entire territory contributing to the fertility of the land. Karun , Iran's most effluent river, 850 kilometers long, flows into the Persian Gulf through this province. The agricultural potential of most of these rivers, however, and particularly in their lower reaches, is hampered by the fact that their waters carry salt ,

660-655: Is also characterized by an overreliance on dam construction and large-scale diversion projects, primarily benefiting politically connected enterprises and urban elites. This has led to the drying of rivers, wetlands, and other vital ecosystems, intensifying dust storms and land subsidence in regions like Khuzestan and Sistan-Baluchestan . Such environmental degradation, combined with insufficient governmental oversight and transparency, worsens living conditions for marginalized communities, reinforcing cycles of poverty and socio-political marginalization. Historically, Khuzestan, one of Iran's most water-rich provinces, has been hit hard by

Khuzestan has desert conditions and experiences many sandstorms. Iran ranks among the most water stressed countries in the world. However, Khuzestan province suffers from major water problems that were aggravated by corruption in Iran's water supply sector, lack of transparency, neglect of marginalized communities, and political favoritism . The Islamic Revolutionary Guard Corps and other politically connected entities control water resources, prioritizing projects for political and economic gain rather than public need. They divert supplies to favored regions, causing shortages in vulnerable provinces like Khuzestan and Sistan-Baluchestan. For example, water diversion projects in Isfahan and Yazd provinces receive priority despite critical shortages in Khuzestan and Sistan-Baluchestan. Reports also indicate that certain agricultural and industrial enterprises with ties to

The group which claimed responsibility for the siege the Arab Popular Movement in Arabistan (See Arab separatism in Khuzestan ) gave a number of press conferences in the following months, referring to what it described as "the racist rule of Khomeini". It threatened further international action as part of its campaign to gain self-rule for Khuzestan. But its links with Baghdad served to undermine its argument that it

1020-717: The Iran–Iraq War of the 1980s, the Arabs of Khuzestan mostly resided in the rural regions along the Karkhe and Karun rivers in the southwest of the province and the number living in cities was very limited because the Arab tribes were still following a nomadic lifestyle. But after the end of the war, most of the refuged Arabs were relocated by the government to the urban centres and smaller towns. This conversion of lifestyle directly from nomadic to city life caused many problems and conflicts in

The Sassanids resettled these tribes in Kerman and Ahvaz . Arabs named Shapur II, as "Shabur Dhul-aktāf" after this battle. The existence of prominent scientific and cultural centers such as Academy of Gundishapur which gathered distinguished medical scientists from Egypt ,

1200-670: The Qajar dynasty "the province was known, as in Safavid times, as Arabistan, and during the Qajar period was administratively a governor-generalate." Half of Khuzestan was not known as Arabistan. Khuzestan's northern, more populous parts, with the capital at Shushtar , retained the old name, but also occasionally was incorporated into the district of the Greater Lur due to the large Bakhtiari population in half of Khuzestan. In 1856, in

1260-565: The Seleucid dynasty weakened, Mehrdad I the Parthian (171–137 BC), gained ascendency over the region. During the Sassanid dynasty this area thrived tremendously and flourished, and this dynasty was responsible for the many constructions that were erected in Ahvaz, Shushtar , and the north of Andimeshk . During the early years of the reign of Shapur II (AD 309 or 310–379), Arabs crossed

The following census in 2011 counted 4,531,720 people in 1,112,664 households. The 2016 census measured

1440-639: The Iranian Revolutionary Guard Corps have received significant amounts of water, while small farmers and rural communities struggle with severe shortages. Iran's central government prioritizes water allocation for industrial and urban centers, often at the expense of rural and minority populations. These groups face severe water shortages, ecological degradation, and a loss of livelihoods. This pattern of unequal development not only exacerbates regional disparities but also fuels social unrest and environmental crises. Iran's water policy

The Muslim settlements by military garrisons in southern Iran was soon followed by other types of expansion. Some families, for example, took the opportunity to gain control of private estates. Like the rest of Iran, the Muslim conquest thus brought Khuzestan under

1680-525: The Sasanian time and throughout the Islamic era, the provincial seat returned and stayed at Shushtar, until the late Qajar period. With the increase in the international sea commerce, arriving on the shores of Khuzistan, Ahvaz became a more suitable location for the provincial capital. The River Karun is navigable all the way to Ahvaz (above which, it flows through rapids). The town was thus refurbished by

In case of the Karun, a single tributary river, Rud-i Shur ("Salty River") that flows into the Karun above Shushtar contributes most of the salt that the river carries. As such, the freshness of the Karun waters could be greatly enhanced if the Rud-i Shur could be diverted away from the Karun. The same applies to

2040-637: The entire province regained the old name and the term Arabistan was dropped. There is also a very old folk etymology which maintains the word "khouz" stands for sugar and "Khouzi" for people who make raw sugar. The province has been a cane sugar-producing area since the late Sassanian times, such as the sugar cane fields of the Dez River side in Dezful .

In recent years, Khuzestan has witnessed a significant exodus of its rural population as people move to cities for work and better living conditions. The situation has been exacerbated by periodic dust storms, which further degrade the environment and make life untenable in affected regions. This environmental migration from Khuzestan has led to social tensions in

High unemployment rate, water crisis, high dust, and lack of civil infrastructure are among

2760-482: The province—south, southwest of the Ahvaz Ridge , had come by the 17th century to be known—at least to the imperial Safavid chancery as Arabistan. The contemporaneous history, the Alam Ara-i Abbasi by Iskandar Beg Munshi , written during the reign of king Abbas I (r. 1588–1629), regularly refers to the southern part of Khuzestan as "Arabistan". The northern half continued to be called Khuzestan. In 1925,

The name of the city of Ahvaz also has

3300-592: The wealth generation of the local oil industry. Minority rights are frequently identified with strategic concerns, with ethnic unrest perceived by the Iranian government as being generated by foreign governments to undermine the country's oil industry and its internal stability.

Many of the famous nakhlestans (palm groves) were annihilated, cities were destroyed, historical sites were demolished, and nearly half the province captured by the invading Iraqi army. This created a mass exodus into other provinces that did not have the logistical capability of taking in such a large number of refugees. However, by 1982, Iranian forces managed to push Iraqi forces out of Iran . The Battle of Khorramshahr (one of Khuzestan's largest cities and
