 Irvine is the site of an incident in 1296 during the Scottish Wars of Independence when an English army marched to Irvine to engage the Scottish army that was encamped at Knadgerhill, only to find that dissension amongst the Scots leaders was so great that armed conflict did not occur and many of the leaders changed sides and joined King Edward I. Bourtreehill House, the only major Estate in the parish, was periodically possessed by all three kings and possibly the Constables of Scotland before them.In December 2010, the writer A. J. Morton stated that Irvine was a "Lost Medieval Capital" and a likely candidate in the debate about the Stone of Destiny and its location before it was moved to Scone.Citing Hector Boece, who said the Stone was kept at Evonium a legendary city and home to the early Scottish crown, Morton said that Irvine's early high status position in the 12th century supported the theory that Irvine is Evonium.
