In 1678 Archibald Campbell, 9th Earl of Argyll led the Campbell of Argyll militia on an expedition to the Isle of Mull and took Duart Castle from the Clan Maclean. However, Argyll was beheaded on 30 June 1685 for his participation in Argyll's Rising in support of the Monmouth Rebellion to depose Catholic James VII and II and place the Protestant James, Duke of Monmouth on the throne. Later in 1692 Archibald Campbell, 1st Duke of Argyll again gained possession of the Maclean's Duart Castle.
