Captain John Porteous was a Scottish military officer who served in the Edinburgh City Guard and played a major role in the Porteous Riots, which resulted in his death.

The Heart of Mid-Lothian is the seventh of Sir Walter Scott's Waverley Novels. It was originally published in four volumes on 25 July 1818, under the title of Tales of My Landlord, 2nd series, and the author was given as "Jedediah Cleishbotham, Schoolmaster and Parish-clerk of Gandercleugh". The main action, which takes place between September 1736 and May 1737, is set in motion by the Porteous Riots in Edinburgh and involves an epic journey from Edinburgh to London by a working-class girl to obtain a royal commutation of the death penalty incurred by her sister for the alleged murder of her new-born baby. Despite some negative contemporary reviews, some now consider it Scott's best novel.
