Ishaq ibn Isma'il

Ishaq b. Isma'il b. Shuab al-Tiflisi (before 833 – 853), also known as Sahak in Georgian sources, was the emir of Tbilisi between 833 and 853. Under his rule, the emirate reached the apex of its power. He forced Georgian princes to pay tribute from Kakheti to Abkhazia. He tried to become independent from the Abbasid caliphate, stopped reversing the tribute, and allied himself with local nobility such as the mtavari of Kakheti. In retribution, the caliph Al-Mutawakkil sent an expedition against him led by Bugha al-Kabir (also known in Georgia as Bugha the Turk), assisted by the Georgian noble Bagrationi family. In 853, they burnt and sacked Tbilisi, and killed the emir.
