Ibn Kundajiq initially accepted, but in 880/1 the coalition against him was renewed, and open warfare broke out. This time, Ibn Kundajiq was victorious in a battle fought in April/May 881, driving his opponents before him to Amid, which he left under siege. A few inconclusive skirmishes followed, and the situation was not resolved by the time of Isa's death in 882/3, as Ibn Kundajiq became involved in the Abbasid efforts to recover Syria from the Tulunids.[12] Isa was succeeded by his son Ahmad, who ruled the Diyar Bakr as an independent prince.
