Germany and Japan, the aggressors of World War II, were not invited to participate.
Though World War II was over, Europe was still ravaged from the war.
When it was announced that the Olympic Games would be resumed, many debated whether it was wise to have a festival when many European countries were in ruins and the people near starvation.
To limit the United Kingdom's responsibility to feed all the athletes, it was agreed that the participants would bring their own food. Surplus food was donated to British hospitals.
No new facilities were built for these Games, but the Wembley Stadium had survived the war and proved adequate. No Olympic Village was erected; the male athletes were housed at an army camp in Uxbridge and the women housed at Southlands College in dormitories.
