Edward III of England
Edward III (13 November 1312 – 21 June 1377) was king of England and Lord of Ireland from January 1327 until his death; 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 long reign of 50 years was the second-longest in medieval England (after that of his great-grandfather Henry III) 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.
Edward was crowned at age fourteen after his father was deposed by his mother, Isabella of France, and her lover Roger Mortimer.
At age seventeen he led a successful coup d'état against Mortimer, the de facto ruler of the country, and began his personal reign.
After a successful campaign in Scotland he declared himself rightful heir to the French throne in 1337.
This started what became known as the Hundred Years' War.
Following some initial setbacks, this first phase of the war went exceptionally well for England; victories at Crécy and Poitiers led to the highly favourable Treaty of Brétigny, in which England made territorial gains, and Edward renounced his claim to the French throne.
This phase would become known as the Edwardian War.
Edward's later years were marked by international failure and domestic strife, largely as a result of his inactivity and poor health.
Edward III was a temperamental man but capable of unusual clemency.
He was in many ways a conventional king whose main interest was warfare.
Admired in his own time and for centuries after, Edward was denounced as an irresponsible adventurer by later Whig historians such as William Stubbs, but modern historians credit him with some significant achievements.
John of Gaunt
John of Gaunt, Duke of Lancaster (6 March 1340 – 3 February 1399) was an English prince, military leader, and statesman.
He was the third of the five sons of King Edward III of England who survived to adulthood.
Due to his royal origin, advantageous marriages, and some generous land grants, Gaunt was one of the richest men of his era, and an influential figure during the reigns of both his father, Edward, and his nephew, Richard II.
As Duke of Lancaster, he is the founder of the royal House of Lancaster, whose members would ascend to the throne after his death.
His birthplace, Ghent, corrupted into English as "Gaunt", was the origin for his name.
When he became unpopular later in life, scurrilous rumours and lampoons circulated that he was actually the son of a Ghent butcher, perhaps because Edward III was not present at the birth.
This story always drove him to fury.
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, and for a time styled himself as King of Castile.
As Edward the Black Prince, Gaunt's elder brother and heir to the ageing Edward III, became incapacitated due 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 extremely unpopular figure for a time.
John exercised great influence over the English throne during the minority of King Richard II, and the ensuing periods of political strife.
He mediated between the king and a group of rebellious nobles, which included Gaunt's own son and heir, Henry Bolingbroke.
Following Gaunt's death in 1399, his estates and titles were declared forfeit to the Crown, and his son, now disinherited, was branded a traitor and exiled.
Henry Bolingbroke returned from exile shortly after to reclaim his inheritance, and deposed Richard.
He reigned as King Henry IV of England (1399–1413), the first of the descendants of John of Gaunt to hold the English throne.
The House of Lancaster would rule England from 1399 until the time of the Wars of the Roses, when the English crown was disputed with the House of York (formed by the descendants both of his younger brother Edmund, Duke of York and his elder brother, Lionel, Duke of Clarence).
Gaunt also fathered five children outside marriage: one early in life by a lady-in-waiting to his mother, the others by Katherine Swynford, his long-term mistress and third wife.
They were later legitimised by royal and papal decrees, but which did not affect Henry IV's bar to their having a place in the line of succession.
Gaunt is ancestor to the English monarchs of the houses of Lancaster by his first wife and Tudor by his mistress and later third wife, whose children bore the surname "Beaufort".
