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 Iranian Intermezzo, also called the Persian Renaissance, was a period in Iranian history marked by the rise to power of the first Iranian Muslim dynasties. Beginning 170 years after the Arab conquest of Iran and lasting until the middle of the 11th century, it is noteworthy since it was an interlude between the decay of Arab power under the Abbasid Caliphate and the rise of Turkic power under the Seljuk Empire, which triggered the Sunni Revival. The Iranian Intermezzo brought an end to Arab hegemony over Iranian lands and revived Iran's national spirit, albeit in conformity with Islam, though there were some non-Muslim movements (e.g., Mardavij) that outright rejected the Islamization of Iran. Although Zoroastrianism continued to decline, the movement did succeed in revitalizing the Persian language, with the most significant Persian literature from this period being the Shahnameh by Ferdowsi. The Iranian dynasties that took part in this effort were the Tahirids, the Saffarids, the Ilyasids, the Ghaznavids, the Sajids, the Samanids, the Ziyarids, the Buyids, the Sallarids, the Rawadids, the Marwanids, the Shaddadids, the Kakuyids, the Annazids, and the Hasanwayhids.
According to the historian Alison Vacca, the Iranian Intermezzo "in fact includes a number of other Iranian, mostly Kurdish, minor dynasties in the former caliphal provinces of Armenia, Albania, and Azerbaijan". Likewise, in the second edition of the Encyclopaedia of Islam, the historian Clifford Edmund Bosworth states that the Russian historian Vladimir Minorsky considers the Rawadids to be flourishing during this period.
The various states and civilizations in Iran (Persia) have had numerous capital cities and royal centers throughout history.
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.
Although Annazid authority declined in several generations, the dynasty did not disappear. In late 12th century, Surkhab III ibn Annaz was a ruler of Luristan.
The Kurds are an Iranian ethnic group in the Middle East. They have historically inhabited the mountainous areas to the south of Lake Van and Lake Urmia, a geographical area collectively referred to as Kurdistan. Most Kurds speak Northern Kurdish Kurmanji Kurdish (Kurmanji) and Central Kurdish (Sorani).
There are various hypotheses as to predecessor populations of the Kurds, such as the Carduchoi of Classical Antiquity. The earliest known Kurdish dynasties under Islamic rule (10th to 12th centuries) are the Hasanwayhids, the Marwanids, the Rawadids, the Shaddadids, followed by the Ayyubid dynasty founded by Saladin. The Battle of Chaldiran of 1514 is an important turning point in Kurdish history, marking the alliance of Kurds with the Ottomans. The Sharafnameh of 1597 is the first account of Kurdish history. Kurdish history in the 20th century is marked by a rising sense of Kurdish nationhood focused on the goal of an independent Kurdistan as scheduled by the Treaty of Sèvres in 1920. Partial autonomy was reached by Kurdistan Uyezd (1923–1926) and by Iraqi Kurdistan (since 1991), while notably in Turkish Kurdistan, an armed conflict between the Kurdish insurgent groups and Turkish Armed Forces was ongoing from 1984 to 1999, and the region continues to be unstable with renewed violence flaring up in the 2000s.
