https://en.wikipedia.org/wiki/Bagrat_II_Bagratuni

Bagrat II Bagratuni (Armenian: Բագրատ Բ Բագրատունի, Arabic: Buqrāṭ ibn Ashūṭ; died after 851) was an Armenian noble of the Bagratid (Bagratuni) family and the presiding prince ("prince of princes") of Arab-ruled Armenia between 830 and 851. He succeeded his father, Ashot IV Bagratuni, as ruler of Taron in 826, and was named presiding prince by the Abbasid Caliph in 830. In 849 he began an open rebellion against Abbasid authority in Armenia. The rebellion provoked the dispatch of Bugha al-Kabir to the country, who crushed the revolt in a three-year campaign. Bagrat was treacherously captured during negotiations in 851 and brought captive to the Abbasid capital Samarra. He was succeeded in Taron by his sons, while the title of presiding prince passed to his nephew, the future King Ashot I of Armenia.
