Edward the Black Prince in the context of "Thomas Felton (died 1381)"

Edward III (13 November 1312 – 21 June 1377), also known as Edward of Windsor before his accession, was King of England from January 1327 until his death in 1377. He is noted for his military success and for restoring royal authority after the disastrous and unorthodox reign of his father, Edward II. Edward III transformed the Kingdom of England into one of the most formidable military powers in Europe. His fifty-year reign is one of the longest in English history, and saw vital developments in legislation and government, in particular the evolution of the English Parliament, as well as the ravages of the Black Death. He outlived his eldest son, Edward the Black Prince, and was succeeded by his grandson, Richard II.

Edward was crowned at age fourteen after his father was deposed by his mother, Isabella of France, and her lover, Roger Mortimer. At the age of seventeen, he led a successful coup d'état against Mortimer, the de facto ruler of England, and began his personal reign. After a successful campaign in Scotland, he declared himself rightful heir to the French throne, starting the Hundred Years' War (1337–1453). Following some initial setbacks, this first phase of the war went exceptionally well for England and would become known as the Edwardian War. Victories at Crécy and Poitiers led to the highly favourable Treaty of Brétigny (1360), in which England made territorial gains, and Edward renounced his claim to the French throne. Edward's later years were marked by foreign policy failure and domestic strife, largely as a result of his decreasing activity and poor health. The second phase of the Hundred Years' War began in 1369, leading to the loss of most of Edward's conquests, save for the Pale of Calais, by 1375.

Richard II (6 January 1367 – c. 14 February 1400), also known as Richard of Bordeaux, was King of England from 1377 until he was deposed in 1399. He was the son of Edward, Prince of Wales (later known as the Black Prince), and Joan, Countess of Kent. Richard's father died in 1376, leaving Richard as heir apparent to his grandfather, King Edward III; upon the latter's death, the 10-year-old Richard succeeded to the throne.

During Richard's first years as king, government was in the hands of a series of regency councils, influenced by Richard's uncles John of Gaunt and Thomas of Woodstock. England at that time faced various problems, most notably the Hundred Years' War. A major challenge of the reign was the Peasants' Revolt in 1381, and the young king played a central part in the brutal suppression of this crisis. Less warlike than either his father or grandfather, he sought to bring an end to the Hundred Years' War. A firm believer in the royal prerogative, Richard restrained the power of the aristocracy and relied on a private retinue for military protection instead. In contrast to his grandfather, Richard cultivated a refined atmosphere centred on art and culture at court, in which the king was an elevated figure.

John of Gaunt, Duke of Lancaster (6 March 1340 – 3 February 1399), was an English prince, military leader and statesman. He was the fourth son (third surviving) of King Edward III, and the father of King Henry IV. Because of Gaunt's royal origin, advantageous marriages and some generous land grants, he was one of the richest men of his era and an influential figure during the reigns of both his father and his nephew, Richard II. As Duke of Lancaster, he is the founder of the royal House of Lancaster, whose members would ascend the throne after his death. His birthplace, Ghent in Flanders, then known in English as Gaunt, was the origin of his name.

John's early career was spent in France and Spain fighting in the Hundred Years' War. He made an abortive attempt to enforce a claim to the Crown of Castile that came through his second wife, Constance of Castile, and for a time styled himself as King of Castile. When Edward the Black Prince, Gaunt's elder brother and heir-apparent to the ageing Edward III, became incapacitated owing to poor health, Gaunt assumed control of many government functions and rose to become one of the most powerful political figures in England. He was faced with military difficulties abroad and political divisions at home, and disagreements as to how to deal with these crises led to tensions between Gaunt, the English Parliament and the ruling class, making him an unpopular figure for a time. He helped forge the 1386 Anglo-Portuguese alliance, secured through the marriage of his daughter Philippa to John I of Portugal, which endured for centuries.

The first phase (Edwardian phase (1337–1360)) of the Hundred Years' War between England and France lasted from 1337 to 1360. It is sometimes referred to as the Edwardian War because it was initiated by King Edward III of England, who claimed the French throne in defiance of King Philip VI of France. The dynastic conflict was caused by disputes over the French feudal sovereignty over Aquitaine and the English claims over the French royal title. The Kingdom of England and its allies dominated this phase of the war, and Edward's sovereignty over Aquitaine was confirmed in the Treaty of Brétigny (1360), although he renounced his claim to the French throne.

Edward had been granted the duchy of Aquitaine in 1325, and as Duke of Aquitaine he was a vassal to Philip VI of France. Due to political trouble in England during his early reign as a minor, Edward initially accepted Philip as King of France, but the relationship between the two kings soured in the 1330s when Philip allied with Edward's enemy, King David II of Scotland. Edward in turn provided refuge to Robert III of Artois, a French fugitive. When Edward refused to obey Philip's demands for the expulsion of Robert from England, Philip confiscated the Duchy of Aquitaine. This precipitated war and, in 1340, Edward declared himself king of France. Edward III and his son Edward the Black Prince, led their armies on a largely successful campaign across France with notable victories at Auberoche (1345), Crécy (1346), Calais (1347), and La Roche-Derrien (1347). Hostilities were paused until the mid-1350s for the deprivations of the Black Death. Then war continued, and the English were victorious at the Battle of Poitiers (1356) where the French king, John II, was captured and held for ransom. The Truce of Bordeaux was signed in 1357 and was followed by two treaties in London in 1358 and 1359.

The Caroline War was the second phase of the Hundred Years' War between France and England, following the Edwardian War. It was so-named after Charles V of France, who resumed the war nine years after the Treaty of Brétigny (signed 1360). In this part of the conflict, the Crown of Castile emerges as a supporter of France. The Kingdom of France dominated this phase of the war.

The Black Prince, eldest son and heir of Edward III of England, spent a huge sum of money in order to restore Peter the Cruel to the throne of Castile. The Castilian King was unable to repay him, however, so the Black Prince raised taxes in his domains in Aquitaine. The people's complaints were unheeded, so they appealed to the French King Charles V. In May 1369, the Black Prince received summons from the French king demanding his presence in Paris. The prince refused, and Charles responded by declaring war. He immediately set out to reverse the territorial losses imposed at Brétigny and he was largely successful in his lifetime. His successor, Charles VI, made peace with the son of the Black Prince, Richard II, in 1389. This truce was extended many times until the war was resumed in 1415.
