Ahvaz
The seat of the province has, for the most of its history, been in its northern reaches, first at Susa (Shush) and then at Shushtar. During a short spell in the Sasanian era, the capital of the province was moved to its geographical center, where the river town of Hormuz-Ardashir (modern Ahvaz). 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.
Arab Spring concurrent incidents
In Iranian Khuzestan, according to Saudi "Al Arabiya", Lebanese Yalibnan, the Guardian, there were large scale protests, declared as "Day of Rage" by Ahvaz Arab minority, in the city of Ahvaz – capital of the Khuzestan province, and the nearby town of Hamidieh. The protests marked six years since the violent 2005 Ahvaz unrest. The protesters were "demanding more rights and humanitarian benefits", as well as independence. The Revolutionary Guard Corps used tear gas to disperse the demonstrations, while using live bullets in some neighborhoods. Al-Arabiya reported that when the protests began, the city was blockaded by Iranian security forces, who "broke up demonstrations by force" and that "15 people from Ahwaz have been killed and dozens have been wounded". The Guardian puts the casualty rate at 12 dead Arabic-speaking Sunnis, based on Shirin Ebadi's letter to the UN.
