Day of Mourning and Protest - Canberra, Australia (26 Jan, 2018)

'The Day of Mourning was a protest held by Aboriginal Australians on 26 January 1938, the sesquicentenary of British colonisation of Australia. It was declared to be a protest of 150 years of callous treatment and the seizure of land, and purposefully coincides with the Australia Day celebrations held by the European population on the same day. The protest became a tradition, and annual Days of Mourning have been held to this day.'
