Under Scots law there was a special category of murder, known as "murder under trust", which was considered to be even more heinous than ordinary murder. The Glencoe massacre was a clear example of such.
The massacre is known as Mort Ghlinne Comhann in Gaelic, meaning the Murder of Glen Coe.
Thirty-eight MacDonalds from the Clan MacDonald of Glencoe were killed by the guests who had accepted their hospitality, on the grounds that the MacDonalds had not been prompt in pledging allegiance to the new monarchs, William and Mary. Another forty women and children died of exposure after their homes were burned.
For several decades, the Scottish Republican Socialist Movement have held a commemoration on the Sunday closest to the anniversary which is often attended by members of other groups including Siol nan Gaidheal, Na Fir Dileas etc. There is also a smaller local commemoration.
