Fourteen-year-old Edward III was crowned King of England, but with the country ruled by his mother Queen Isabella and her lover Roger Mortimer.

Edward III, 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.

This list of kings and reigning queens of the Kingdom of England begins with Alfred the Great, who initially ruled Wessex, one of the seven Anglo-Saxon kingdoms which later made up modern England. Alfred styled himself king of the Anglo-Saxons from about 886, and while he was not the first king to claim to rule all of the English, his rule represents the start of the first unbroken line of kings to rule the whole of England, the House of Wessex.

Isabella of France, sometimes described as the She-Wolf of France, was Queen of England as the wife of King Edward II, and de facto regent of England from 1327 until 1330. She was the youngest surviving child and only surviving daughter of King Philip IV of France and Joan I of Navarre. Isabella was notable in her lifetime for her diplomatic skills, intelligence, and beauty. She overthrew her husband, becoming a "femme fatale" figure in plays and literature over the years, usually portrayed as a beautiful but cruel and manipulative figure.

Roger Mortimer, 3rd Baron Mortimer of Wigmore, 1st Earl of March, was an English nobleman and powerful marcher lord who gained many estates in the Welsh Marches and Ireland following his advantageous marriage to the wealthy heiress Joan de Geneville, 2nd Baroness Geneville. Her mother was of the royal House of Lusignan. In November 1316, he was appointed Lord Lieutenant of Ireland. He was imprisoned in the Tower of London in 1322 for having led the marcher lords in a revolt against King Edward II in what became known as the Despenser War.
