Sanandaj's founding is fairly recent, (about 250 years ago), yet in its short existence it has grown to become one of the centers of
Kurdish culture. During the
Iran–Iraq War the city was attacked by Iraqi planes and saw disturbances. Since 2019, UNESCO has recognized Sanandaj as Creative City of Music. The name "Sinna" first appears in records from the 14th century CE. Before this, the main city in the region was
Sisar, whose exact location is unknown. Sisar was also called "Sisar of Sadkhaniya", or "Sisar of the hundred springs", and it has been proposed that the current name of "Sinna" is a contracted form of "Sadkhaniya". The name "Sisar" disappears in the 14th century and the name "Sinna" replaces it, for example in the works of
Hamdallah Mustawfi who refers to a mountain and a pass with this name. Then the Kurdish historian
Sharaf al-Din Bitlisi mentions that in 1580 an
Ardalan ruler named Timur Khan had a land grant including Sinna and the earlier Ardalan capital of
Hasanabad. However, the local historian Ali-Akbar Munshi Waqayi-Nigar wrote in 1892/3 that Sinna was founded later, by the ruler
Soleyman Khan Ardalan, on the site of an earlier settlement; the
chronogram he gives for this event corresponds to 1046
AH, or 1636-7 CE. Sinna was developed significantly under the reign of Aman Allah "the Great" (from 1797-1825). 19th-century Sinna was "a lively commercial center, exporting
oak galls,
tragacanth, furs, and carpets". Its population was mostly
Kurdish, with a significant
Jewish minority and smaller numbers of
Armenian and
Assyrian Christians (the latter of which are predominantly
Chaldean Catholic). ==Demographics==
