The Kings of England are the monarchs who have ruled over England since the early medieval period. The first king often recognized is Egbert, who united various kingdoms in the 9th century. The monarchy has seen many significant figures, including William the Conqueror, who established Norman rule in 1066, and Henry VIII, known for his six marriages and the English Reformation. Throughout history, the monarchy has evolved, with various dynasties such as the Plantagenets, Tudors, and Stuart families. The role of the king has changed from absolute power to a constitutional monarchy, where the monarch's powers are limited by law and Parliament.
