Although England was separated from continental Europe, it could not avoid the typical problems of a medieval country such as wars, epidemics, rebellions. The external problem was the Hundred Years' War. The domestic ones were the plague epidemic and the peasants' revolt. Each of the issues had an impact on the chronology of English history, influencing how it achieved what we observe now. The Hundred Years' War began as a dynastic conflict on the lines of the house of Capetians, today this series of armed conflicts between England and the Duchy of Burgundy on the one hand and the Auld Alliance of France and Scotland on the other is known as the Hundred Years' War. At first England succeed. The victory over the French navy at the Battle of Crécy (1346) gave them the opportunity to establish themselves in Calais, one of the Atlantic ports, and to use it as a landing point in their further advance inland. At the Battle of Poitiers (1356) and Agincourt the skill of the English archers defeated the French army which was 6 times larger and consisted mostly of cavalry. Despite visible success, England lost the war. Having failed to conquer Orleans, they were defeated at the Battle of Pates, allowing the Dauphin to crown himself Charles VII. In 1449 the French reconquered Roanne and Cannes. The English army under John Talbot attempted to repel Gascony, but lost at the Battle of Castillon in 1453. That was the last battle of the war, which ended with the capitulation of an English garrison at Bordeaux. As a result, England lost all its French territories except Calais. This fact and the king's madness plunged the country into a series of magnate wars. The war led to the development of the army: the infantry...... middle of paper...... individual feudal charges, but also against the feudal system itself. Despite the defeat, the rebellion helped accelerate the liberation of the peasants and the replacement of serfdom with monetary rent, which led England to a gradual transition from feudal to capitalist society. To summarize, let's say that the period from 1300 to 1500 cannot be called insignificant. Irreplaceable loss of life, expenditure of large amounts of money and resources, as well as the process of progress could be observed. The Hundred Years' War ended heavy dependence on France. The Black Death helped peasants realize the inequality of the feudal system and forced landowners to raise workers' wages. The peasants' revolt was one of the first attempts to realize the idea of ​​\u200b\u200bhuman rights and innate freedom, and the country for the people, not for the king and his court.
