Omavid Rule
Around this time, the news of the assassination of second Islamic Caliph, Omar, spread throughout the Islamic territories. An Iranian prisoner called Peerooz, killed Omar while he was on prayer. Omar’s successor, Othman, who was a very weak ruler did not encourage Arab armies to continue their conquests as fast as they did during Omar’s reign, so Iranian freedom fighters got more time to organize themselves. These early revolutionaries were usually from the noble families, called “vasteriushan” in Sasanid empire, they really did nothing, mostly because of lack of popularity.
In the next 20 years, Arabs completed their conquest of Iran, and they established their first empire, Omavid Dynasty. Omavid rulers where amongst the most cruel of the Islamic rulers. During their 98 years of Caliphate, many of the invaded territories began their independence movements.
