According to the research by an archeological team in the burnt city, women comprised the most powerful group in this 5000-year-old city.

The archeological team has found a great number of seals in the women's graves. In ancient societies, holding a seal was a sign of power, and was of 2 kinds: personal and governmental.

The burnt city ancient site located in Sistan-Baluchistan province, southeastern Iran, dates back to between 2000 and 3000 BC.

"In the ancient world, there were tools used as a means of economic control. Whoever had these tools at his disposal was among the most powerful people in the society", Mansour Sajjadi, the Iranian archeologist responsible for excavations in the burnt city told CHN.

According to Sajjadi, during the excavations in the burnt city cemetery, 90% of the graves in which the seals were found belonged to women. Only 5% of these seals were found in men's graves.
