"Scots Wha Hae" (English: Scots Who Have; Brosnachadh Bhruis) is a patriotic song of Scotland written using both words of the Scots language and English, which served for centuries as an unofficial national anthem of the country, but has lately been largely supplanted by "Scotland the Brave" and "Flower of Scotland".
The lyrics were written by Robert Burns in 1793, in the form of a speech given by Robert the Bruce before the Battle of Bannockburn in 1314 during the Scottish Wars of Independence. Although the lyrics are by Burns, he wrote them to the traditional Scottish tune "Hey Tuttie Tatie", which according to tradition, was played by Bruce's army at the Battle of Bannockburn. According to tradition, the same theme was played in 1429 by the Franco-Scots army at the siege of Orléans in front of Joan of Arc. The song, called "Marche des soldats de Robert Bruce" in France, belongs to the traditional list of military music, and commemorates the Auld Alliance between France and Scotland. As for the Battle of Bannockburn, the theme really played was probably a traditional Scottish theme such as "Hey Tuttie Tatie". The tune tends to be played as a slow air, but certain arrangements put it at a faster tempo, as in the Scottish Fantasy by Max Bruch, the concert overture Rob Roy by Hector Berlioz, and the Real McKenzies' punk rock rendition on their 1998 album Clash of the Tartans.
The song was sent by Burns to his publisher, George Thomson, at the end of August 1793, with the title "Robert Bruce's March To Bannockburn", and a postscript saying that he had been inspired by Bruce's "glorious struggle for Freedom, associated with the glowing ideas of some other struggles of the same nature, not quite so ancient." This is seen as a covert reference to the Radical movement, and particularly to the trial of Glasgow lawyer Thomas Muir of Huntershill, whose trial began on 30 August 1793 as part of a government crackdown, after the French Revolutionary Wars led to France declaring war on the Kingdom of Great Britain on 1 February 1793.
