What areas of land does Rupert's land cover?

Rupert's Land no longer exists.

The Hudson's Bay Company was incorporated by Royal Charter on May 2, 1670. Prince Rupert, a cousin of the king, was the most prominent shareholder of the Hudson's Bay Company. The land granted to the Hudson's Bay Company by the Charter came to be called Rupert's Land.

The land included in the grant was the entire drainage area of present day Hudson Bay (including James Bay). This was roughly two-thirds of modern day Canada, plus large portions of the States of North Dakota, South Dakota, and Minnesota.

Around 1870, the Hudson's Bay Company transferred its rights in the land to Canada, and Britain transferred the territory to Canada, thus bringing Rupert's Land to an end.

Today, the Hudson's Bay Company continues as the world's oldest commercial corporation.
