Armenian revolts against Umayyads
ArmeniaThe Armenians launched a large revolt against the Umayyads in 702, requesting Byzantine aid. Abdallah ibn Abd al-Malik launched a campaign to reconquer Armenia in 704 but was attacked by Heraclius, brother of Emperor Tiberius III in Cilicia. Heraclius defeated the Arab army of 10,000–12,000 men led by Yazid ibn Hunain at Sisium, killing most and enslaving the rest; however, Heraclius was not able to stop Abdallah ibn Abd al-Malik from reconquering Armenia.
