Political context of Europe in the 14th century
The so-called Hundred Years' War was one of the most prolonged conflicts of medieval Europe, taking place between 1337 and 1453. It primarily pitted the kingdoms of England and France against each other over territorial control and dynastic legitimacy regarding the French throne.
The conflict arose within a context of feudal rivalries inherited from the time of the Plantagenet dynasty, when English monarchs held significant territories in France, especially the Duchy of Aquitaine.
These tensions were exacerbated by trade disputes, political rivalries, and the gradual weakening of the feudal system in Western Europe.

Dynastic causes of the conflict
The immediate cause of the war relates to the succession crisis of the French throne following the death of King Charles IV of France in 1328, without a direct male heir.
English King Edward III of England claimed the throne of France due to his kinship with the Capetian dynasty through his mother, daughter of Philip IV of France.
However, the French nobility invoked the so-called Salic law, which prevented the crown from being transmitted through the female line, and proclaimed Philip VI of France as king.
This dynastic disagreement generated a deep rivalry between both monarchies and became the trigger for the armed conflict.
Territorial and economic interests
In addition to the dispute over the crown, there were economic and territorial interests that aggravated the confrontation.
England relied heavily on the wool trade with the textile centers of Flanders, a region economically linked to the French kingdom, although politically complex.
At the same time, the control of territories such as the Duchy of Aquitaine generated constant tensions between both kingdoms.
The rivalry for these strategic regions meant that the conflict was not only a dynastic war, but also a struggle for the economic and political control of important areas of Western Europe.

Major battles and military changes
During the war, decisive clashes occurred that transformed medieval military history.
Among them is the Battle of Crécy in 1346, where the use of the English longbow demonstrated its great effectiveness against French feudal cavalry.
Years later, the Battle of Poitiers took place in 1356, in which the French king John II of France was captured.
Another crucial confrontation was the Battle of Agincourt in 1415, where the English army once again defeated French forces superior in number.
These battles reflect the transition from feudal warfare based on cavalry toward more organized forms of combat, where disciplined infantry and new tactics acquired greater prominence.
The role of Joan of Arc and the turning point of the conflict
In the 15th century, the course of the war changed significantly with the appearance of the figure of Joan of Arc. This young peasant claimed to receive divine visions that urged her to support the French heir to the throne.
Her intervention was decisive in the liberation of the city of Orléans in 1429, an event that strengthened French morale and allowed for the coronation of King Charles VII of France.
Although Joan was captured by the Burgundians and subsequently executed in 1431, her actions helped to revitalize French resistance against English rule.

Political and social consequences
The conflict concluded in 1453 with the French victory following the Battle of Castillon, which ended English rule in most of the French territory.
As a result, France consolidated its process of political centralization under the monarchy, while England lost almost all its continental possessions, retaining only the port of Calais for a few more years.
The war also caused significant military transformations, such as the development of artillery and the progressive decline of feudal cavalry.
Furthermore, the conflict contributed to the emergence of more defined political and national identities in both kingdoms.
Historical significance of the Hundred Years' War
The Hundred Years' War profoundly marked the political evolution of Western Europe.
Beyond its duration, the conflict transformed feudal structures and favored the strengthening of centralized monarchies.
It also spurred military innovations and changes in the organization of standing armies.
For these reasons, historians consider that this war represents a historical transition between the classical Middle Ages and the new forms of political power that would characterize the Europe of the Modern Age.
