A royal charter granted the Hudson's Bay Company a monopoly in the fur trade in Rupert's Land (present-day Canada).

A royal charter is a formal grant issued by a monarch under royal prerogative as letters patent. Historically, they have been used to promulgate public laws, the most famous example being the English Magna Carta of 1215, but since the 14th century have only been used in place of private acts to grant a right or power to an individual or a body corporate. They were, and are still, used to establish significant organisations such as boroughs, universities and learned societies, and were historically used to establish companies.
