Janah ad-Dawla was the atabeg of
Ridwan and participated in the failed campaign of Ridwan's father
Tutush I to gain the Seljuk throne, which ended with the latter's death in the battle of Rayy in 1095. Thereafter, he fled to Aleppo, where he managed to persuade the garrison of the
citadel to recognise Ridwan as their ruler. In 1095, he clashed in battle with Turkish forces of Yusuf bin Abaq, another former Turkish commander under Tutush who had joined
Yağısıyan, the Turkish governor of Antioch. Thereafter, Janah and Yağısıyan attempted to take the city of Edessa, but its Greek governor
Thoros managed to keep the city and afterwards Janah and Yağısıyan were at odds. The following two years Janah and Ridwan campaigned against Ridwan's brother
Duqaq, the ruler of Damascus, but were unable to achieve anything. After another battle on 22 March 1097, Janah and Ridwan fell out and Janah had to flee to Homs, which he came to rule. He later joined
Kerbogha's army during the second
siege of Antioch in 1098. He was murdered by three
Assassins in 1103, apparently by order of
al-Hakim al-Munajjim and apparently instigated by Ridwan. ==References==
