Cause → Event → Consequence
Clan Gregor and Clan Colquhoun were engaged in a long-running feud stemming from MacGregor raids on Colquhoun lands. The Colquhouns secured royal backing and assembled an armed force to confront the MacGregors, escalating the local dispute into a formal armed engagement.
On 7 February 1603, the two clans and their respective allies clashed in the valley of Glen Fruin in Dunbartonshire. Despite the Colquhouns' royal support and raised army, the MacGregors defeated them comprehensively on the battlefield.
Following the battle, the Crown turned its punitive attention on the victorious MacGregors rather than the defeated Colquhouns. Royal policy suppressed Clan Gregor for approximately 150 years as punishment for the violence and disruption caused by the engagement.
