What is "Rupert’s Land" now known as?

Rupert's Land was a vast continental expanse — a third of what is now Canada (with a small portion in the United States)— which from 1670–1870 was the exclusive commercial domain of the Hudson's Bay Company. Rupert’s Land was named in honour of Prince Rupert, the cousin of England's King Charles II, who became the HBC's first governor.

Three years after Confederation (1867) the government of Canada acquired Rupert's Land from the Company for $1.5-million: the largest real estate transaction (by land area) in the country's history.

Geographically, the Rupert's Land purchase transformed Canada from a modest country in the northeast corner of North America, into an expansive nation stretching north and west across the continent. Rupert's Land would eventually be apportioned out between the provinces of Québec, Ontario and Manitoba, and later, upon their creation, to Saskatchewan, Alberta, and the Northwest Territories.

Prince Rupert had been forgotten or abandoned at 11 months by his nurse as the household fled the approaching army in Prague in 1620. A final search of the palace by the royal chamberlain saved baby Rupert, who was tossed into the last carriage to leave the castle. Rupert survived to grow up in exile, land at the court of his English royal relatives as an adult, and use his influence to establish the Hudson’s Bay Company, thereby shaping Canada’s destiny.
