British Arctic Territories were territories claimed by Britain in North America, consisting of the islands of what is now known as the Canadian Arctic Archipelago (excepting islands in Hudson Bay, which were part of Rupert's Land). The region was part of British North America.
The British claim to the area was based on the discoveries of Martin Frobisher (1535–1594) in the 16th century. Britain passed control of the islands to Canada in 1880, by means of an Imperial Order in Council, the Adjacent Territories Order, passed under the Royal Prerogative. After the 1880 transfer Canada gradually incorporated the islands with Rupert's Land into the Northwest Territories. The transfer was necessary over the fear of American interest in the area as part of the Monroe Doctrine.
On April 1, 1999, the territory of Nunavut was created from the eastern portion of the Northwest Territories. The majority of the islands became part of Nunavut. Islands split between Nunavut and Northwest Territories includes Victoria Island, Melville Island, Mackenzie King Island and Borden Island.
These islands were never part of either the North-Western Territory or Rupert's Land, which covered the mainland of northern North America. Canada had acquired those regions in 1870, creating the Province of Manitoba and the new North-West Territories.
