The Glencoe Massacre occurred in February 1692 in the Scottish Highlands, specifically in the village of Glencoe. It involved the killing of members of the MacDonald clan by government troops loyal to the Crown. The massacre was part of a larger conflict between the Scottish clans and the British government, which sought to enforce loyalty to the Protestant King William III. The event was marked by betrayal, as the MacDonalds had been granted safe passage by the government but were still attacked. Over 30 clan members were killed, and many others were left homeless. The massacre remains a significant and tragic event in Scottish history, symbolizing the brutal conflicts of the time.
