The conspiracy of Pontcallec is noted for its ineffectiveness and the confused aims of its leaders. Only a small fraction of the Breton nobility in general took part and the Breton people as a whole were excluded since its professed intent was to defend the established rights and liberties of the nobility. Despite this the conspiracy quickly acquired legendary status in Brittany and Pontcallec's death turned him into a folk hero.
Théodore Hersart de la Villemarqué discusses his actions in his historical notes to
Barzaz Breiz (The Ballads of Brittany), in which he included a ballad
Marv Pontkalleg (The Death of Pontcallec), praising "le jeune marquis de Pontcallec, si beau, si gai, si plein de cœur" (the young Marquis de Pontcallec, so handsome, so gay, so full of heart). This song became very popular in Brittany, and has been recorded by
Alan Stivell,
Gilles Servat and
Tri Yann. Le Villemarqué's notes portray Pontcallec as a rebel who led a Breton independence movement supported by both the aristocracy and the people, stating that "the Bretons declared the act of union with France null" and that they had sought Spanish help to secure the "absolute independence of Brittany". The interpretation was repeated by the
Breton nationalist movement, which depicted him as a martyr: the Breton equivalent of
Wolfe Tone and
Patrick Pearse.
Arthur de la Borderie in
La Bretagne aux Temps Modernes 1471-1789 (1894) stated that the rebellion was a legitimate reaction to a centralising and potentially
despotic monarchy, adding that the names of the victims are "enrolled in the most glorious place in our martyrology ... it was the last blood spilt for the law, constitution and freedom of Brittany." In
Jeanne Coroller-Danio's
Histoire de Notre Bretagne (1922) the conspiracy is presented as an heroic act of resistance to French oppression. In 1979 a plaque was placed at the site of the executions by
Raffig Tullou's nationalist group
Koun Breizh stating that "defenders of Breton liberty" were decapitated on the spot "by royal order". The Pontcallec Conspiracy is dramatized in
Alexandre Dumas's novel ''
The Regent's Daughter (1845), which tells the story of two lovers mixed up in the events of the conspiracy. It is also central to the 1975 film Que la fête commence (English title Let Joy Reign Supreme''), directed by
Bertrand Tavernier and starring
Philippe Noiret as the Regent and
Jean-Pierre Marielle as Pontcallec. ==Notes==
