The Battle of Culloden in 1746 brought the Jacobite cause—led by Bonnie Prince Charlie [1720-1788] to restore the House of Stuart to the throne of the Kingdom of Great Britain—to a decisive defeat.

The victors conducted a form of ethnic cleansing known as the Highland Clearances. 

New laws attacked the Highlanders' clan system, and Highland dress was outlawed.
