Al-Hajjaj ibn Yusuf

Abū Muhammad al-Ḥajjāj ibn Yūsuf ibn al-Ḥakam ibn ʿAqīl al-Thaqafī, known simply as al-Hajjaj ibn Yusuf, was perhaps the most notable governor who served the Umayyad Caliphate. He began his service with the Umayyads under Caliph Abd al-Malik, who successively promoted him as the head of the caliph's shurta, the governor of the Hejaz in 692–694, and the practical viceroy of a unified Iraqi province and the eastern parts of the Caliphate in 694. Al-Hajjaj retained the last post under Abd al-Malik's son and successor al-Walid I, whose decision-making was highly influenced by al-Hajjaj, until his death in 714.
