The Persian revolts against the Rashidun Caliphate were a series of uprisings and insurgencies across former Sasanian territories between 646 and 661 CE. Following the initial Muslim conquest of Persia, these rebellions represented a major challenge to the consolidation of Rashidun control over the territories of the former Sasanian Empire. The unrest was primarily driven by the marginalization of the Persian elite and economic discontent regarding the imposition of taxes such as the Jizya and Kharaj.
The revolts intensified during the reigns of caliphs Uthman and Ali, particularly in provinces such as Fars, Khorasan, Kerman, and Tabaristan. In cities like Istakhr, the rebellions were frequent and often required multiple military expeditions to suppress. Local Zoroastrian populations and remnants of the Sasanian army occasionally coordinated these efforts, at times providing support to the last Sasanian emperor, Yazdegerd III.
Internal instability during the First Fitna provided further opportunities for regional revolts. However, Arab commanders, including Abd Allah ibn Amir and Ziyad ibn Abihi. eventually re-established Rashidun control through a series of decisive campaigns.These conflicts resulted in significant casualties and paved the way for the stabilization of the region under the succeeding Umayyad Caliphate.
Background
The Persians revolted against the early Muslim caliphs due to several factors including cultural, religious, and economic discontents. After the fall of the Sasanian Empire and the Arab conquests, Persian culture experienced a severe setback. Much of the population viewed the Arab rule as a foreign occupation over the indigenous institutions and an imposition of non-indigenous government structures. Arabic became the language of administration with Persian elites losing their power over the state which led to further cultural conflicts.
Socio-economic conflicts
The followers of Zoroastrianism found themselves increasingly discriminated and marginalised. Initially the Arabs considered them to be the People of the Book, however due to high taxation and restrictions over the years widespread discontent in the region. The destruction of fire temples and religious customs further made Arab rule unpopular among the population. Economically, many Persians suffered under the taxation of the Jizya and Kharaj, particularly under corrupt governors. This became an important factor for several revolts throughout the region, like the Tabaristan uprising and other localized resistance to Arab rule.Daniel, Elton L. The History of Iran.

Islamic sources recognise the Persian resistance faced during its conquest. The Isfahan province held a rebellion after its initial submission, requiring renewed military efforts to re-establish Arab control over it.Political Development - III, History of Islam.

Rebellions against Uthman
Early Rebellions in Shahpur & Kazerun The rebellions in Persian regions broke out significantly due to the instability caused by the changing of governors of Basra and Kufa or in the early days of a new caliph. Similarly, after the murder of the second Rashidun caliph Umar, the cities of Shahpur and Kazerun rose in revolt.
Rebellions in Ray & Hamdan In the early years of Uthman's reign, during the second instigation of Sa'd ibn Abi Waqqas as the governor of Kufa, the cities of Hamdan and Ray rose in revolt against the Arabs. Sa'd sent Ala ibn Wahab to suppress the revolt in Hamadan. Ray was suppressed by Qarza ibn Ka'b al-Ansari and made to pay the kharaj and jizya taxes. The peace made with the nobility of the city in 646 failed to last long.
Azerbaijan Insurrection
In 646, during the governorship of Sa'd ibn Abi Waqqas, the people of Azerbaijan region held an insurrection against the Arabs. Sa'd responded by invading Mughan, Talish and sent raiding campaigns upto Armenia.
Istakhr Rebellions
Istakhr Rebellion (650) At the instigation of Yazdegerd III, the people of Fars rose in revolt. Abdallah ibn Ma'mar al-Tamimi, an Arab governor, was killed by Persian rebels in Istakhr. The rebels then invited Yazdegerd III to the city while he was en route to Khorasan. In response, Abd Allah ibn Amir, an Arab general and governor of Basra, established himself as governor of Fars on behalf of the Caliphate to restore order. Meanwhile, an Iranian general named Mahak captured Darabgerd from the Arabs. After Ibn Amir managed to conquer Jūr, he then returned to suppress the rebellion of Istakhr after the people of Istakhr broke the treaty between them and the Arabs. Ibn Amir subsequently surrounded the city with his Basran cavalry. After fierce fighting and bombarding the city by using a Manjānīq, the rebellion was suppressed and 40,000 Persians were killed, including members from noble houses and Aswaran commanders who had taken refuge in Istakhr.
Istakhr Rebellion (653) In 653, a revolt broke out in Istakhr during the reign of Caliph Uthman following the refusal of paying the Jizya. Abd Allah ibn Abbas was sent to crush the rebellion, and the rebellion was suppressed. Abd Allah ibn Amir and Ubaydallah ibn Ma'mar al-Taymi as his vanguard set out for Istakhr. The Persians confronted Ubaydallah at Ramjird and killed him. He was buried in a garden of the town. Ibn Amir hurried organised his army upon learning of the event and laid siege to Istakhr. He appointed Abu Barza Nadla ibn Abd Allah al-Aslami in his right wing, Ma'qil ibn Yasar al-Mazani in his left wing, Imran ibn al-Husayn al-Khuzā'ī was given the charge of the cavalry and Muhammad ibn Mu'ammar al-Dhuhli in charge of infantry. They fought the rebels of Istakhar, routed them, and killed 100,000. Ibn Amir then recaptured Darabjird and headed for Kerman.
Kurdish Rebellion in Izeh A rebellion organised by the Kurds broke out in Idha (modern-day Izeh) during the reign of the Caliph Uthman. Abu Musa al-Ash'ari, the governor of Basra, called for war against the rebels but failed to gain popular support for the campaign. Upon the Basrans' request to remove Abu Musa from his office, Uthman dismissed him and appointed Abd Allah ibn Amir as his replacement.
Conflict in Tabaristan
After the assassination of Caliph Umar, several regions in Iran rose in revolt. A Muslim force under Suwyd ibn Muqran launched an military assault on Amol. The governor agreed to pay the Muslims tribute after receiving the guarantee of no further military assault on the town by the Muslims. However, the population of Amol refused to pay the tribute, triggering a Muslim attack on the city through Gorgan by Sa'id ibn al-As to force Amol to pay the tribute. The attack triggered widespread revolts in Tabaristan against the Caliphate authorities.
Sa'id ibn al-As along with Hasan ibn Ali and Husayn ibn Ali launched an expedition to Tabaristan. He besieged Abrashahr before camping at Qumis. He later arrived in Tamisah, where he captured the fort of Tamisah. Sa'id also captured the Namiyah desert.
Revolts of Darabgard and Fasa & Campaigns to the East Rabi ibn Ziyad al-Harithi was sent to carry out military campaigns in the Sistan region which was captured during the reign of the Caliph Umar but rose in revolt under Uthman. Darabgard and Fasa revolted but was suppressed. The first conflict took place in Zaliq during a Persian festival. The Muslims emerged victorious and the Persians sought peace. The Arab Muslim army captured Qarquqya without any resistance, then launched military expeditions in the regions of Afghanistan.
Uprising in Zaranj Two years later after Ibn Ziyad's campaign, the people of Zaranj rose up against the Arab lieutenant and expelled him. Abd Allah ibn Amir sent Abd al-Rahman ibn Samura who recaptured Zaranj and made new territorial gains in the regions of Bust and Zabul.
Kerman Revolt (651–652) Kerman also rebelled in 651-652, but the revolt was suppressed by Abd Allah ibn Amir. The Arab forces searched the entire province and moved southwards towards Hormuz. The Persian refugees in Kerman scattered in all directions as a result of the conflict.
Merv Rebellion After Uthman sent Umayr ibn Ahmar, Abd Allah ibn Amir encamped near Merv. During the winter season, the people of Merv agreed on the entrance of Ibn Amir into the city. The Dehqan feared that Umayr and his troops would perish in the cold, hence they gave them shelters in their own houses. They later regretted the decision and planned an attack against Umayr. The military leader and Dehqan of the town, Baraz ibn Māhrūya immediately informed Umayr of the planned attack on them. The urban rowdies and market traders of the town carried out the attack. On learning that the people of Merv were planning a revolt against them, Abd Allah ibn Amir suppressed the civilians in the city. Uthman rebuked Ibn Amir for his actions.
Insurrection of Qarin/Karen After the campaign of Ibn Amir in the frontier of the Oxus River, the Caliphate had a small armed presence in the regions of Merv, Nishapur, and Zaranj. After Ibn Amir left with most of his troops, an Iranian notable named Qarin raised an insurrection in Quhistan and began collecting forty thousand recruits from Herat, Tabasain, and Badgihas. The insurrection took place during the last years of Uthman's reign. The Arabs were driven out of Nishapur and Zaranj, while the Nezak Huns captured Balkh. The Arabs stationed at Merv held off the siege until Abd Allah ibn Khazim al-Sulami was sent by Ibn Amir to suppress the revolt. Ibn Khazim set out with 4000 troops to confront Qarin. Qarin and many of his supporters were killed and the insurrection was suppressed. These regions were in the Hephthalite dominated areas of Herat, which further indicates towards a Qarinvand - Hephthalite alliance. Ibn Amir played an important role in responding to the revolt which occurred during the assassination of Uthman. Ibn Khazim attacked the rebels during night and defeated them. Mutual co-operation between the Parthian nobility and the Hephthalites were seen throughout the Sasanian frontier. The Hephthalites launched raids around Murghab. The alliance between the Māhawayh, Nezaks, Qarinids, and Hephthalites to resist the Arabs were a brief continuation of the traditional strategy which was followed during Sasanian times.
