The Hundred Years' War, a major conflict between France and England that profoundly marked European medieval history, officially began in 1337. This long confrontation, which will span more than a century, finds its roots in complex political, economic and dynasty tensions. Understanding the root causes of this outbreak, as well as the early clashes and military strategies employed, is essential to grasp the scale and challenges of this war that shaped Europe.
The root causes of the outbreak in 1337
The outbreak of the Hundred Years' War in 1337 resulted from an accumulation of factors related to land and dynasty claims. The main cause was the conflict around the throne of France: Edward III of England claimed the French crown by his mother, daughter of Philip IV, which was disputed by the French nobility who preferred Philip VI, from the younger Capetian branch. Moreover, economic tensions linked to the control of rich regions such as Flanders, as well as disputes over sovereignty in Aquitaine, exacerbated rivalries. This unstable environment added to a succession of internal crises and an emerging nationalism, paving the way for prolonged war.
First clashes and key military strategies
The first confrontations of the war were marked by a series of flash campaigns and skirmishes where British tactical superiority was quickly felt. The English, under the direction of Edward III, used their archers effectively, especially the long arch, which inflicted heavy losses on the French knights in decisive battles such as that of Crécy in 1346. The English strategy was based on mobility, the defence of key positions and the exploitation of military technology, while the French, despite their number and prestigious chivalry, struggled to adapt to the new methods of combat. These early English successes established a model of war that would influence the following decades.
The beginning of the Hundred Years War in 1337 marked the beginning of a conflict that would redefine Franco-English relations and have profound repercussions on the military and political development of medieval Europe. Understanding the causes of its outbreak and the first military strategies makes it possible to appreciate the complexity and brutality of this war, which would profoundly change the face of the kingdoms involved.
