history
he province has a rich Paleolithic heritage. Many caves with Paleolithic remains have been surveyed or excavated there. some of these cave sites are located in Bisetun and north of Kermanshah. The first known physical remains of Neanderthal man in Iran was discovered in Bisitun Cave. Do-Ashkaft, Kobeh, Warwasi, and Mar Tarik are some of the Middle Paleolithic sites in the region. Kermanshah also has many Neolithic sites, of which the most famous are Ganj Dareh, Sarab, and Asiab. At Ganj Dareh, the earliest evidence for goat domestication have been documented. In May 2009, based on a research conducted by the University of Hamedan and UCL, the head of Archeology Research Center of Iran's Cultural Heritage and Tourism Organization announced that the oldest prehistoric village in the Middle East dating back to 9800 B.C., was discovered in Sahneh, located in west of Kermanshah.
The monuments found in Kermanshah show two glorious periods, the Achaemenid and Sassanid eras. The mythical ruler of the Pishdadian is described as founding the city while Tahmores Divband built it. An alternative narrative is that the construction was by Bahram IV of the Sassanid dynasty during the 4th century CE. Kermanshah reached a peak during the reign of Hormizd IV and Khosrau I of Sassanids, before being demoted to a secondary royal residence.
The city suffered major damage during the Arab invasions but recovered in the Safavid period to make great progress. Concurrent with the Afghan attack and the fall of Isfahan, Kermanshah was almost completely destroyed by the ottoman invasion.
During the Iran–Iraq War the province suffered heavy fighting. Most towns and cities were badly damaged and some like Sar-e Pol-e Zahab and Qhasr-e-Shirin were almost completely destroyed.
The November 2017 Iran–Iraq earthquake killed more than 600 people.
On December 28, 2017 Kermanshah became one of several Iranian provinces to break out into protests. The Supreme Leader of Iran has blamed western interference. Some female organizations such as The National Council of Resistance of Iran (NCRI) have taken partial credit for the organization of these protests.
