Cette thèse de doctorat étudie les liens entretenus entre les sociétés politiques de Dijon et de Lille et le pouvoir princier sous les deux derniers ducs de Bourgogne (1419-1477), en interrogeant la manière dont les bourgeois l’ont apprécié en termes d’opportunité, se sont associés au fonctionnement de l’État princier et investis au service du prince. Toutes deux capitales d’un ensemble multipolaire de principautés dont elles sont deux des principales villes francophones, Dijon et Lille appartiennent à deux espaces géopolitiques diversement intégrés (le premier, marginal ; l’autre, central) et rarement observés ensemble. L’analyse, portée à partir des milieux dirigeants, souligne l’originalité avec laquelle ces liens s’établissent. Les dijonnais sont étroitement associés à l’exercice du pouvoir princier, là où les Lillois séparent strictement implication municipale et service du prince, mais sont étroitement liés à l’entourage ducal. La sociologie du pouvoir municipal comme des éléments de contexte régional expliquent les différences remarquées. Au-delà de ces différences, l’investissement bourgeois, qui s’articule à un ensemble d’activités parmi lesquelles l’exercice du pouvoir municipal reste toujours décisif, participe à l’évolution des sociétés urbaines, et, amorçant leur intégration à une société politique d’ordre territorial, et induit une adaptation pragmatique des pratiques politiques des Villes. La disparition de Charles le Téméraire confirme cette capacité d’adaptation des sociétés bourgeoises, qui réorientent à leur profit vers de nouveaux pouvoirs les liens élaborés auprès des ducs de Bourgogne. / This PhD thesis is about the relationship between political societies of Dijon and Lille and princely power under the last two dukes of Burgundy (1419-1477) studying the manner the citizens felt it in terms of appropriateness and how they associated to the princely state and got involved in serving it. Both capitals of a multipolar body of principalities of which they are two of the main French-speaking towns, Dijon and Lille belong to two geopolitical, diversely integrated areas (the former marginal, the latter central) and seldom observed together. The analysis seen from the ruling circles emphasizes the originality with which their links work out. The inhabitants of Dijon are closely associated with the prince’s exercising of power whereas the inhabitants of Lille strictly separate town implication from prince service though both closely related to the ducal entourage. The municipal power sociology together with regional context elements can explain those observed differences. Beyond them, the citizens investment, which is articulated to a set of activities among which the town exercise of power always remains decisive, takes part in urban societies development and initiating their integration in a political territorial society, induces a pragmatic adaptation of town practical politics. The death of Charles the Bold confirms this ability of bourgeois societies to adapt themselves and redirect the ties built with the dukes of Burgundy towards new powers for their benefit.

This is no surprise coming from a man who was born into a people who had their own celebrated founder and foundations, and immersed himself in the writings of classical republicans and the quasi-mythical histories of ancient city-states where the heroic lawgiver played an important and legitimate role in political foundations. However, Rousseau's propositional political writings (those written for Geneva, Corsica, and Poland) have been accused of being unsystematic and running the spectrum from conservative and prudent to radical and utopian. It is this seeming incongruence which is the subject of this thesis. In particular, it is argued that this confusion is born out the failure to recognize a systematic distinction between "founding" and "re-founding" political societies in both the history of political thought, and Rousseau's own work (a distinction in Rousseau which has rarely been noted, let alone treated to a study of its own). By recognizing this distinction one can identify two Rousseaus; the conservative and prudent thinker who is wary of making changes to established political systems and constitutional foundations (the re-founder), and the radical democrat fighting for equality, and claiming that no state is legitimate without popular sovereignty (the founder). In demonstrating this distinction, this thesis examines the ancient concept of the lawgiver, the growth and expansion of the idea leading up to the eighteenth century, Rousseau's own philosophic writings on the topic, and the differing political proposals he wrote for Geneva, Corsica, and Poland. The thesis argues that although there is a clear separation between these two types of political proposals, they remain systematically Rousseauvian.
