North-western Iran comprises diverse geographical landscapes, including pastures of piedmonts, mountains, and well-watered plains. The present chronology of this region, nevertheless, is based exclusively on data collected from sites around the Urmia Lake, other regions being almost totally ignored. During the late Bronze Age (hereafter LBA) a new way of life took shape in the mountainous region, the most outstanding characteristic of which was fortified settlements. This paper attempts to revise the chronology of North-western Iran by deciphering LBA materials from some of these sites.
