English mythology is the collection of myths that have emerged throughout the history of England, sometimes being elaborated upon by successive generations, and at other times being rejected and replaced by other explanatory narratives. These narratives consist of folk traditions developed in England after the Norman Conquest, integrated with traditions from Anglo-Saxon mythology, Christian mythology, and Celtic mythology. Elements of the Matter of Britain and Welsh mythology which relate directly to England are included, such as the foundation myth of Brutus of Troy and the Arthurian legends, but these are combined with narratives from the Matter of England and traditions from English folklore.
