Summary

In 448 AH the caliph al-Qa'im bi-Amr Allah married the sister of Tughril Beg. The caliph's position was strengthened and the caliphate grew in standing through Tughril Beg's sultanate 1.

What the marriage meant

This marriage was a bond between the Abbasid caliphate in Baghdad and the rising Seljuq sultanate. It came after years in which the caliphs had been weak before the Buyid amirs. Later the reverse happened: Tughril Beg married the caliph's daughter in 454 AH 2.

The battle of al-Basasiri and the sermon for the Ubaydi al-Mustansir in Baghdad

Arslan al-Basasiri grew so mighty he was preached on the minbars and the caliph decided nothing without him; when his ill creed proved out and his plan to sack the palace surfaced, al-Qa'im wrote secretly to Tughrul Beg at Rayy. Tughrul came in 447; al-Basasiri fell back to Rahba, took the Egyptian al-Mustansir's money and the treacherous brother Inal's distraction. In 450 he entered Baghdad under Egyptian banners — the khutba went to al-Mustansir at the Mansur mosque, 'hayya ala khayr al-amal' entered the adhan — and seized the caliph in Dhu'l-Hijja, jailing him at Ana; the caliph's letter to God was hung on the Ka'ba. Tughrul killed Inal, had the caliph returned in honour on 25 Dhu'l-Qa'da 451, and al-Basasiri's head reached Baghdad.
