 Hasanlu archaeological joint project in partnership with Iranian-American archaeologist is the one of the rare long-term archaeological projects carried out in northwest of Iran. In the process of this project (۱۹۵۷-۱۹۷۸), the layers from the Neolithic period to the historical period have been excavated. The Seventh period of Hasanlu Tepe is contemporary of early bronze age and the beginning of massive economic and social mutation in the cultural developments context of Middle East. Cultural materials of this period in Hasanlu Tepe have illuminated the obvious cultural differentiation between southern area of Urmia lake and the whole of Iran northwest region. Although the short report on this period material have been published, but there is still very little awareness on this period around the pottery types and its distribution, burial traditions and relationship between neighbors. Therefore, the present study intends to introduce the general characteristics of the culture of the seventh period of Hasanlu by referring to the findings of Hasanlu project and other excavations carried out in this area. cultural materials of this period illuminates that during the third millennium BC, there have been a distinguished socio-cultural zone from the Kura-Araxes area with painted Orange and Red pottery characteristic in the southern part of Lake Urmia to the southern slopes of Sahand Mountains. Which on the one hand interacted with northern Mesopotamia in west and on the other hand interacted with the Kura-Araxes communities in whole of north, eastern and southern area.
