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.
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.
