Ahvaz (Persian: اهواز‎, romanized:Ahvāz or Ahwaz) is a city in the southwest of Iran and the capital of Khuzestan province. Ahvaz's population is about 1,300,000[2] and its built-up area with the nearby town of Sheybani is home to 1,136,989 inhabitants. It is home to Persians, Arabs, Lurs (Bakhtiaris), Dezfulis, Shushtaris, etc.[3] and different languages are spoken in it, such as Persian, Arabic,[4][5] the Persian dialects of Luri (Bakhtiari), Dezfuli, Shushtari, etc.[6]
Oil was found near Ahvaz in the early 20th century, and the city once again grew and prospered as a result of this newfound wealth. From 1897-1925, the city of Ahvaz was in the hands of heshmatoddoleh Ghajar, whom acted as governor and Sarhang Reza Gholi Khane Arghoon as commander of Ghajari's army based in Khuzestan. Khaz'al Khan/Sheikh Khaz'al was appointed by Mozaffareddin shah / Mozaffar ad-Din Shah Qajar in Khorramshahr, Sardar Asad Bakhtiari as the most powerful leader of Khuzestan's Bakhtiaries. He had power and authority over most regions of Khuzestan, such as Dezful, Shushtar, Izeh, even Ahvaz and Amir mojahede bakhtiari in Ramhormoz and Behbahan. At this time, the newly founded Ahvaz was named Nâseri in honour to its founder Nassereddin Shah Qajar. Afterwards, during the Pahlavi period, it resumed its old name, Ahvaz. The government of the Khūzestān Province was transferred there from Shûshtar in 1926. The Trans-Iranian Railway reached Ahvaz in 1929 and by World War II, Ahvaz had become the principal built-up area of the interior of Khūzestān. Professional segregation remained well marked between various groups in that period still feebly integrated: Persians, sub-groupings of Persians and Arabs. Natives of the Isfahan region held an important place in retail trade, owners of cafes and hotels and as craftsmen.[14]

In 2011, another wave of protests by Arab tribes occurred mostly in the urban area of Ahvaz. Before 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 structure of their societies and ultimately has led to some unrest.

However, later in 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 Khuzestan, Ahvaz became a more suitable location for the provincial capital. The River Karun is navigable all the way to Ahvaz (above which, the Karun flows through rapids). The town was thus refurbished by the order of the Qajar king, Naser al-Din Shah and renamed after him, Nâseri. Shushtar quickly declined, while Ahvaz/Nâseri prospered to the present day.

The word Ahvaz is a modern Persianized form of the Arabic "Ahwaz" which in turn, is derived from an older Persian word. The Dehkhoda Dictionary specifically defines the "Suq-al-Ahvaz" as "Market of the Khuzis", where "Suq" is the Elamite word for market, and "Ahvaz" is a broken plural (اسم جمع) of the form "af'āl" (افعال) of the word "Huz", which itself comes from the Persian Huz, from Achaemenid inscriptions where the term first appears. Thus, "Ahvaz" in Persian means "the Huz-i people", which refers to the Khuzi original inhabitants of Khūzestān.
