Aq Sunqur was one of the Türkmen begs that were assigned in 1084 by Sultan Malik-Shah I to aid Fakhr ad-Dawla ibn Jahir in the capture of the Uqaylid realm.
[4] Because of his policy to make order in the city, it became a suitable place for trading and farming, the economy recovered and inflation went down.
[4] In 1089, Aq Sunqur was sent together with Bozan and Yağısıyan by Malik Shah to aid his brother Tutush to capture cities that the Fatimids had reconquered under Badr al-Jamali.
However, the coalition fell apart when Aq Sunqur refused to continue the siege of Tripoli after he had been bribed and claimed the city had proclaimed allegiance.
Aq Sunqur was defeated and captured in battle on 27 May 1094 after a part of his Türkmen defected.
