The skirmish was the result of enmity between the House of Hamilton and the "Red"
Angus line of the House of Douglas who were locked in a struggle for supremacy since the death of
King James IV. James' death at the
Battle of Flodden in 1513 had created a power vacuum in the Kingdom of Scotland. Scotland at this time was under the
regency of Angus' rival,
John Stewart, Duke of Albany, but he had been detained in France since 1516. In his absence, a council of senior nobles and clergy were to share power; which included Arran and Angus. Albany (who was born in France to a French mother) also added a French ally to the council as a more neutral party,
Antoine d'Arcy or De la Bastie. d'Arcy was murdered in September 1517 by members of the
Home family with whom he had a feud and this implicated their allies the Douglases and by extension Angus. The murder of a French noble sparked a diplomatic incident and in response the council voted to place Arran as their leader Margaret in response attempted to use her influence with her brother King Henry VIII, the absent Regent Albany and her husband's rival Arran to improve her situation. Arran, at the head of the Hamiltons, was determined to stop his rival Angus from gaining control over King James V however Arran had sided with the Leith merchants, supported by
Robert Barton. Barton was a shipowner of considerable political influence and cited a privilege granted to him by James IV that allowed him to avoid abiding by import and export customs. By ignoring the rights of the Edinburgh burgesses, Arran lost their support and instead they supported the side of Angus during the skirmish. ==The Skirmish==
