Today we look at the brutal killing of an estimated 30 members of the MacDonald Clan by the Earl of Argyll's Regiment. Made an example for allegedly failing to pledge allegiance to the new monarchs, William III of Scotland and Mary II. We look at the religious undertone to this, as well as the wider geopolitics. Why where the McDonalds chosen? Did the massacre help to radicalise the Jacobite movement and future rebellions? Was the context of the House of Stuart important? How did the infamy of the massacre spread and what where the repercussions in London? An what was the result of an inquiry into 'Slaughter under Trust?'
