William Bolts (7 February 1739 – 1808) was a Dutch-born British merchant active in India. He began his career as an employee of the East India Company, and subsequently became an independent merchant. He is best known today for his 1772 book, Considerations on India Affairs, which detailed the administration of the East India Company in Bengal which began shortly after their victory in the Battle of Plassey in 1757. The observations and experiences he recorded offer a unique resource for scholars inquiring into the nature of Company rule in Bengal. Throughout his life, Bolts continued to propose and execute various trading ventures on his own behalf and in conjunction with various commercial and governmental partners. The ventures of individual traders like Bolts did much to spur governments and large corporations into the expansion of their own interests.
