When Dutch come to Indonesia archipelago, they brought many rules related to their legal system and until now Indonesia still adopted their rules such as Civil Code (Burgelijk Wetboek), Commercial Code (Wetboek van Koophandel), these codes were practically Dutch translation from French Code Civil and Code du Commerce.
