The Scottish Highland Massacre of Monzievaird took place on 21 October 1490, at the church of Monzievaird, at Ochtertyre, near Hosh in Perthshire. Some sources give the date as 1511. It was the culmination of a violent blood feud between the Murray and Drummond families. Although feuding, murdering kin, and marrying enemies was commonplace for Highlanders at the time, the massacre was nevertheless notorious and sensational in its day.
