History and Culture
Zanjan province is one of the historical regions of Iran. The antiquity of the province can be divided into four historic periods:
Pre-historic age (from ih millennium BC. till early 3rd millennium BC.): The most ancient and recognized historical vestiges belonging to pre-historic age goes to "Bardostin" culture which are known by small tools having about 30,000 years of antiquity.
Historic age (early 3rd till late 2nd millennium Be.): Human settlements in Eajrood region of Zanjan in 3rd and 2nd millennium Be. indicates flourishing and sustainability of Iran's civilization in this region. Evaluation of black engravings on discovered earthenware of buff color shows the linkage and continuity of Damghan Hesar hill, Kashan Sialk hill, and Eajrood of Zanjan civilizations.
New historic age (late 2nd millennium BC. to early 7th century AD.): The most distinct vestiges of this period is a kind of simple gray earthenware which conforms to simultaneity of Aryan tribes migration to this region. Teapot shape earthenware with relatively long hose were found in all tombs of this age which could be attributed to funeral ceremonies. There have not been a determinate government system in the region till early first millennium Be. Even Othartoui government could not expand its dominance over this region due to remoteness of it. According to Assyrians' documents, this region was named Andya in 9th century BC. and its dwellers have probably communicated with Lulubi and Gouti tribes who resided in slopes of Zagross mountain range. There is ambiguity about the history of the region from 7th century BC. to late millennium Be. i.e. whole Achaemenian period.
The discovered coins "Derik" and "Riton" in Khodabendeh are the vestiges of Achaemenian period. The valleys of Zanjan Rood and Ghezel Ozan were more thriving in Parthians and Sassanians times. Amongst the most important remains of this period Tashvir fire-temples can be pointed out.
Islamic period (from 7th to 19th century Ae.): This period begins with conquest of Iran in the time of Osman caliphate. Existing texts and evidences show that this region was very thriving from economic, cultural and artistic points of view during the whole Islamic period. One of the reasons for selecting Sultanieh as capital by Mongol llkhanan was economic briskness of the region in 7'h and 8th centuries AH.
After the decline of llkhani government by Sarbedaran movement in 9th century AH., Zanjan was attacked by Taymour the lame and was damaged badly. The region was relatively thriving from economic and cultural points of view in Safavid and Ghajar time specially during the reign of Shah Tahmasb and Agha Mohammad Khan.
