Piracy or the use of violence by various types of ships or vessels to take the property of the passengers of other ships or vessels has been one of the important maritime threats from the past until today. During the Middle Ages until the 19 th century, due to the flourishing sea trade, in the Indian Ocean, this phenomenon was widespread, but few scattered reports of it have remained. This research aims to explain the geographical and cultural relationship between the history and modern forms of piracy in the Indian Ocean, to provide a constructive analysis of the roots of piracy nowadays. Based on this, in this research, with a library method and a descriptive-analytical method, and by referring to the most important historical sources and research, scattered reports of piracy during the first to thirteenth centuries AH were analyzed. At the same time, by using analytical studies in cultural criminology, an attempt has been made to analyze this phenomenon from the perspective of deterministic theories and subcultures. Thus, it has been shown that the geography and aspects of the piracy culture in the Indian Ocean are consistent with this phenomenon today. It has also been shown that the inclusive Iranian governments have played the most effective role in fighting this phenomenon; it has been suggested that in today's approach to the phenomenon of piracy, the cultural view of the social and political roots of this phenomenon should be considered. In dealing with it, the fundamental methods of the cultural solution should be used in confrontation with the phenomenon, together with legal and military actions. It has also been suggested that the Iranian government should play a trans-regional cultural effort to revive its historical role in controlling this phenomenon.
