paragraph_text: Treaty of Kiel to World War II (1814–1945)
  
  When the union between the crowns of Denmark and Norway was dissolved in 1814, the Treaty of Kiel severed Norway's former colonies and left them under the control of the Danish monarch. Norway occupied then-uninhabited eastern Greenland as Erik the Red's Land in July 1931, claiming that it constituted terra nullius. Norway and Denmark agreed to submit the matter in 1933 to the Permanent Court of International Justice, which decided against Norway.
  
  Greenland's connection to Denmark was severed on 9 April 1940, early in World War II, after Denmark was occupied by Nazi Germany. On 8 April 1941, the United States occupied Greenland to defend it against a possible invasion by Germany. The United States' occupation of Greenland continued until 1945. Greenland was able to buy goods from the United States and Canada by selling cryolite from the mine at Ivittuut. In World War II, the United States military used Bluie as a code name for Greenland, where they kept several bases named "Bluie (East or West) (sequential numeral)". The major air bases were Bluie West-1 at Narsarsuaq and Bluie West-8 at Søndre Strømfjord (Kangerlussuaq), both of which are still used as Greenland's major international airports.
  
  During this war, the system of government changed: Governor Eske Brun ruled the island under a law of 1925 that allowed governors to take control under extreme circumstances; Governor Aksel Svane was transferred to the United States to lead the commission to supply Greenland. The Danish Sirius Patrol guarded the northeastern shores of Greenland in 1942 using dog sleds. They detected several German weather stations and alerted American troops, who destroyed the facilities. After the collapse of the Third Reich, Albert Speer briefly considered escaping in a small aeroplane to hide out in Greenland, but changed his mind and decided to surrender to the United States Armed Forces.
  
  Greenland had a protected and very isolated society until 1940. It was a colony, and it was believed that its society would be subject to exploitation or even eradication if the country was opened up. The Danish government had maintained a strict monopoly of Greenlandic trade, allowing no more than small scale barter trading with British whalers. In wartime Greenland developed a sense of self-reliance through self-government and independent communication with the outside world. Despite this change, in 1946 a commission including the highest Greenlandic council, the Landsrådene, recommended patience and no radical reform of the system.
