'The name of Yorta Yorta elder William Cooper shines bright in the history of Aboriginal activism in Australia between the two world wars. It is linked with the formation of the Australian Aborigines’ League, of which he was the founding secretary; the Day of Mourning on the anniversary of white settlement in 1938; and a petition intended for George V, signed by almost 2,000 Aboriginal people and demanding Aboriginal representation in parliament. This last was perhaps Cooper’s most cherished project. He spent years gathering signatures and waiting for the most opportune moment to present it; his disappointment at the indifferent response of the Australian government darkened his final years.'
