Massacre of Glencoe: Almost 80 Macdonalds at Glen Coe, Scotland are killed early in the morning for not promptly pledging allegiance to the new king, William of Orange.

The Massacre of Glencoe took place in Glen Coe in the Argyll region of the Scottish Highlands 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 II/III and his wife Mary II.

Clan Donald, also known as Clan MacDonald, is a Highland Scottish clan and one of the largest Scottish clans. Historically the chiefs of the Clan Donald held the title of Lord of the Isles until 1493 and two of those chiefs also held the title of Earl of Ross until 1476.
