when did the referendum occur and in what states
Australian referendum, 1967 (Aboriginals) The Australian referendum of 27 May 1967, called by the Holt Government, approved two amendments to the Australian constitution relating to Indigenous Australians. Technically it was a vote on the Constitution Alteration (Aboriginals) 1967,[1] which became law on 10 August 1967 following the results of the referendum. The amendments were overwhelmingly endorsed, winning 90.77% of votes cast and carrying in all six states.[2] These amendments altered sections 51(xxvi),[3] and 127,[4] having the immediate effect of including Aboriginal Australians in determinations of population, and also empowered the Federal Parliament to legislate specifically for this racial group. The other question put in the referendum, to allow the number of seats in the House of Representatives to be increased without increasing the number of senators, was rejected. It received majority support in only one state – New South Wales – and received about 40.25% "yes" votes nationwide.[5][6]
Twenty-sixth Amendment to the United States Constitution On March 23, 1971, a proposal to lower the voting age to 18 years was adopted by both houses of Congress and sent to the states for ratification. The amendment became part of the Constitution on July 1, 1971, three months and eight days after the amendment was submitted to the states for ratification, making this amendment the quickest to be ratified.
