John Comyn III of Badenoch, the Red Comyn

John Comyn III, the Red Comyn (c. 1274–1306), was the leading noble of the Balliol party. Son of the Black Comyn and nephew of King John Balliol, he served as Guardian after Balliol's 1296 abdication, commanding resistance to the English.

On 10 February 1306 he met Robert the Bruce at a church in Dumfries, where Bruce stabbed him to death before the high altar. The murder cleared Bruce's path to the crown and began a Comyn blood feud.
