In the first coronation ceremony ever held for an English monarch, Edgar the Peaceful is crowned King of England, having ruled since 959 AD. His wife, Ælfthryth, is crowned queen, the first recorded coronation for a Queen of England.

Edgar, known sometimes as Edgar the Peacemaker or the Peaceable, was King of the English from 959 until his death in 975. He became king of all England on his brother Eadwig's death. He was the younger son of King Edmund I and his first wife, Ælfgifu. A detailed account of Edgar's reign is not possible, because only a few events were recorded by chroniclers and monastic writers, who were more interested in recording the activities of the leaders of the church.

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.

May 11 is the 131st day of the year in the Gregorian calendar; 234 days remain until the end of the year.

Ælfthryth was Queen of the English from her marriage to King Edgar in 964 or 965 until Edgar's death in 975. She was a leading figure in the regency during the minority of her son King Æthelred the Unready between 978 and 984.
