Böritigin

Böritigin is first mentioned some time after 1034, when he was imprisoned by the sons of the deceased Ali-Tegin, who was from the eastern branch of the family, known as the "Hasanids".

However, Böritigin eventually managed in 1038 to escape to his brother who was at Uzgend,[3] and then raised an army consisting of Kumiji tribes from the upper Oxus river.

[3] In 1042, the newly crowned Ghaznavid ruler Maw'dud invaded the territories of the Seljuqs and conquered much of Khorasan.

The Seljuqs then extended their rule as far as Vakhsh and appointed a certain Abu 'Ali ibn Shadhan as the governor of their new conquests.

[9] He also had a daughter named Terken Khatun who later married the son of Alp Arslan, Malik-Shah I.
