Cleanse the Causeway
The skirmish known as Cleanse the Causeway, or Clear the Causeway, took place in the High Street of Edinburgh, Scotland, on 30 April 1520, between rival noblemen James Hamilton, 1st Earl of Arran, chief of Clan Hamilton, and Archibald Douglas, 6th Earl of Angus, chief of Clan Douglas. == Background == 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.
