World War II had devastating impacts on Britain that continued long after the war ended. It bankrupted Britain and the country relied on loans from the US to pay for reconstruction. The government introduced identity cards and rationing to manage scarce resources and control the black market. Rationing of food lasted until 1954. The identity card system was later used to implement the National Health Service. Non-British soldiers also made major contributions to the British forces, including over 2.5 million Indians and Gurkhas who fought throughout Asia and Africa.
