The 1976 All Blacks tour of South Africa went ahead, and the Springboks won by three Tests to one, but coming shortly after the Soweto riots the tour attracted international condemnation. Twenty-eight countries boycotted the 1976 Summer Olympics in protest, and in 1977 the Gleneagles Agreement discouraged any Commonwealth sporting contact with South Africa. In response to the growing pressure, the segregated South African rugby unions merged in 1977. A planned 1979 Springbok tour of France was blocked by the French government.
