The Hasanwayhids or Hasanuyids (Kurdish: حەسەنوویییەکان) were a Twelver Shia Kurdish dynasty reigning the western parts of Iran such as Iranian Azerbaijan and Zagros Mountains between Shahrizor and Khuzestan from c. 959 to 1015. The last Hasanwayhid ruler died in 1015 in Sarmadj, south of Bisotun, as the Seljuks began entering the region.

The Annazids or Banu Annaz, Ayyarids, Banu Ayyar (990/991–late 12th century) was a Kurdish Sunni Muslim dynasty which ruled an oscillating territory on the present-day frontier between Iran and Iraq for about 130 years. The Annazids were related by marriage to the Hasanwayhids who they were in fierce rivalry with. The legitimacy of the Annazid rulers stemmed from the Buyid amir Bahāʾ al-Dawla and the dynasty relied on the Shadhanjan Kurds.
