"The Massacre of Glencoe (Scottish Gaelic: Murt Ghlinne Comhann) took place in Glen Coe in the Highlands of Scotland on 13 February 1692. An estimated 30 members and associates of Clan MacDonald of Glencoe were killed by Scottish government forces, allegedly for failing to pledge allegiance to the new monarchs, William III and Mary II."
