Explorers in the Mekong Delta of Vietnam have found a Sanskrit copper-plate grant issued by the Pallava court in the 7th century. The plate is revolutionary as it contains a section dedicated to 'Samudra-Bhaya'—a primitive form of maritime insurance intended to compensate merchants for goods lost to piracy or storms.
The find confirms that the Pallava Empire not only traded with Southeast Asia but established a formal legal and financial framework to protect its overseas merchant guilds. This is the earliest known instance of such a sophisticated maritime insurance system in the Indian Ocean world.
