Quraysh ("'Alam al-Din", who has ruled Mosul…

Quraysh ("'Alam al-Din", who has ruled Mosul since 1052, has acknowledged the supremacy of the Seljuqs, although had at one point come into conflict with them and was temporarily expelled from Mosul.

He had accompanied the Turk Basasiri when the latter took Baghdad at the end of 1058, but the Seljuqs had retaken the city in the next year.

Quraysh, who died in 1061, had been followed by his son Muslim ("Sharaf al-Dawla").

Sharaf al-Dawla is a just ruler; the 'Uqaylid domains will remain relatively stable for most of his reign.

He has been able to bring the 'Uqaylid dynasty to the height of its power.

By allying himself with the Seljuq sultans Alp-Arslan and Malik-Shah, Muslim has annexed part of northern Syria and thus established 'Uqaylid rule over an area reaching from Aleppo to Baghdad.
