United Nations Security Council Resolution 435

United Nations Security Council Resolution 435, adopted on September 29, 1978, put forward proposals for a cease-fire and UN-supervised elections in South African-controlled South West Africa which ultimately led to the independence of Namibia. Importantly, it established the United Nations Transition Assistance Group (UNTAG) which oversaw the election and the South African withdrawal.

The resolution was adopted by 12 votes to none; Czechoslovakia and the Soviet Union abstained while the People's Republic of China did not participate in the vote.

On December 22, 1988, South Africa agreed to implement the resolution upon its signature of the Tripartite Accord at Mount Etjo Lodge in Central Namibia (also known as the Mount Etjo Accord).
