Coniston massacre
The board sat for 18 days in January 1929 to consider three incidents (Brooks, Morton and Tilmouth) that resulted in the deaths of Aboriginal people, and in one more day, finished its report, finding that 31 Aboriginal people had been killed and that in each case the death was justified.
Mahon mac Turlough Mantach Ó Briain
Tim Robinson points out that royal charter of 1545 determined that ""Exemption from tolls for all ships entering this way made Galway, now at the peak of its prosperity, virtually a free port. The Clann Thaidhg O'Briens of Aran were no longer such important allies."" This seems to have been a root cause of the dispute that led to Mahon's death. The Annals of the Four Masters record that in the year 1565:
""Mahon, the son of Turlough Mantach ... was treacherously slain in his own town of Aircín, in Aran, by his own associates and relations. When the chief men of Galway heard of this, they set out to revenge this misdeed upon the treacherous perpetrators, so that they compelled them to fly from their houses; and they the fugitives went into a boat, and put to sea; and where they landed was in the harbour of Ross, in West Corca-Bhaiscinn. Donnell, the son of Conor O'Brien, having heard of this, he hastened to meet them with all the speed that he could exert; and he made prisoners of the greater number of them, and carried them in close fetters to Magh Glae, in the upper part of Corcomroe, in order that their sorrow and anguish might be the greater for being in view of the place where they had perpetrated the crime; he hanged some of them, and burned others, according as their evil practices deserved.
