The Massacre of Glencoe occurred in February 1692 in the Scottish Highlands. It involved the killing of members of the MacDonald clan by government troops loyal to King William III. The massacre was part of a larger conflict between the Scottish clans and the English crown, as the MacDonalds had not sworn allegiance to the king in time. Over 30 MacDonald men, women, and children were killed, while many others were left homeless in the harsh winter. The event is remembered as a tragic betrayal and has become a symbol of the struggles faced by the Scottish clans during this period.
