The 1956 Olympics in Melbourne were affected by a number of boycotts. Egypt, Iraq and Lebanon announced they would not participate in the Games in response to the Suez Crisis when Egypt was invaded by Israel, Britain and France after Egypt nationalised the Suez canal. Meanwhile, the Soviet Union crushed the Hungarian Revolution, leading to the withdrawal of the Netherlands, Spain, and Switzerland. Less than two weeks before the Opening Ceremony November, the People's Republic of China chose to boycott the event because Taiwan, officially the Republic of China had been allowed to compete.China did not compete in the Olympics again until Los Angeles 1984.
