Persian Gulf has been the first sea where man has been able to navigate there. This sea road which connects East of Asia, its banks and islands with Persian Gulf and other regions of Asia and finally Europe, has been of great importance in the history. As the land roads were not safe and secure and the capacity of the ships was suitable for passenger and goods transportation, most of traders and merchants preferred sea road to the other ways. The navigation rules and regulations at this region were in a form that there was no need of being military force for keeping sea transportation security. During the 16th century A.D. the arrival of the European forces has changed many of the traditional usages and influenced on the marine trading in this region. It is assumed that legal system which has been applied in sea trading between Persian Gulf and east of Asia were rules such as the right to innocent passage, freedom of navigation principal, the immunity of extraterritorial ships and their crew.
