[1] The legitimacy of the Annazid rulers stemmed from the Buyid amir Bahāʾ al-Dawla and the dynasty relied on the Shadhanjan Kurds.

[1] The Annazids principally controlled Kermanshah, Hulwan, Dinavar, Shahrizor, Daquq, Daskara, Mandali and Numaniyah.

For this reason, his territory fluctuated greatly; at its highest it reached Hillah, while it at its lowest was limited to western Iran.

As a reaction the Buyids in Hamadan released the son of Badr ibn Hasanwayh, Tahir b. Hilal, who had been captured by them during battle.

In 1029, Abu’l-Šawk went on to fight and defeat the Shams al-Dawla and the Oghuz Turks capturing Hamadan, Dinavar and Asadabad.

Shortly after, in 1045, Turkmen ruler Tughril sent his half-brother Ibrahim Inal to Kurdish areas and Abu’l-Šawk had to flee from Dinavar to Kermanshah and then to the citadel of Sirvan on the Diyala River where many Kurds rallied around him.

Inal later allocated more land in the region to the Annazid dynasty but Mohalhel ultimately died in Seljuk captivity.

Seen in the wider context of the period’s particularism, the increasing conflict between Būyids, Kākuyids, and Saljūqs discouraged the establishment of a political and socio-economic stability similar to that of the previous Kurdish regimes of the Marwānids, Shaddādids, and the Ḥasanūyid Badr.After the Annazid era, the territory was incorporated into Khorshidi territory.
