The role of media in ancient Iran

In today's world, the media has a very wide role in conveying messages and social communication. Studies in ancient Iran show that the transmission of messages through humans, birds, symbols and signs (fire, minaret, tin, sculpture, etc.) It has been. in the governments of ancient Iran, due to the constant conflict with foreigners, especially the Parthian and Sassanid conflicts with the Romans, the spy and intelligence apparatus played a more effective role. But in general, the news and information system in the early days of the Achaemenid rule was wider and more organized than the Parthian and Sassanid dynasties and became the basis for subsequent dynasties. Now the question is whether the media was important in ancient Iran. What media were used in transmitting and receiving the message, was there a change in the transmission of the message, in which dynasties of ancient Iran was news and information more diverse? The results of the research show that informing and receiving news was important because it helped to exercise the king's power, prevent riots, monitor the behavior of the dependent states and counter the invasion of enemies. The resources available in the libraries have been used to do the work, and the research methodology is narrative in nature.
