Answer
Ibn al-Ash'ath was a leader of a mass rebellion in Iraq in 701 that was crushed by Al-Hajjaj. The rebellion began when Ibn al-Ash'ath, who was the governor of Kufa, refused to pay tribute to the caliph in Damascus. He was supported by the people of Kufa, who were unhappy with the high taxes that were being levied by Al-Hajjaj.
