The island (the 61st-largest island in the world and Canada's 15th-largest island) and the surrounding area was the region where the Erebus and Terror ended up.
It is now known the two ships became stranded in 1846 when frozen in the sea ice northwest of the island. After abandoning the two ships, most of the crew died from exposure and starvation as they attempted to walk south near the western coastline. Two of Franklin's men were buried at Hall Point on the island's south coast. It wasn't until June 29, 1981, that researchers finally had luck. A team led by Canadian archaeologist Owen Beattie, found 31 pieces of human bone fragments on the southern tip of the island, called Booth Point. On September 9, 2014 the Victoria Strait Expedition located the wreck of HMS Erebus. The HMS Terror, was found in 2016 in Terror Bay, off the south-west coast of King William Island.
The area also played an important for the Norwegian explorer Roald Amundsen on the expedition through the Northwest Passage, spending nearly two years with his ship on the SE coast at what is now known as Gjoa Haven. The island is separated from the Boothia Peninsula by the James Ross Strait to the northeast, and the Rae Strait to the east. To the west is the Victoria Strait and beyond it Victoria Island. Within the Simpson Strait, to the south of the island, then the Adelaide Peninsula, part of mainland Canada. Queen Maud Gulf lies to the southwest.
