Summary: ended in the conclusion of a convention prohibiting the commerce of the Ostend Company in the East Indies between the Company’s charter in 1723 and their completion of a new treaty. The protests against Ostenders’ activities were made by English factors in Bengal from trade and controversies with foreign competitors to their illegal trading and ribald behaviour. The remarkable commercial success of the East India Company in Bengal led to a fierce competition between different European settlements, particularly with the Ostenders, who resorted to smuggling and illicit trade, sparking diplomatic challenges and controversies which eventually culminated in prohibiting the Ostenders’ trading activities. Through strategic alliances and negotiations, the English Company managed to protect its interests and maintain its dominant position in the economic landscape of Bengal.
