What treaty has a document not specifically linked to Wedmore that is a Treaty of Alfred and Guthrum, that was the result of an army of the Anglo-Saxon kingdom of Wessex under Alfred the Great defeating the Great Heathen Army?
Battle of Edington At the Battle of Edington an army of the Anglo-Saxon kingdom of Wessex under Alfred the Great defeated the Great Heathen Army led by Guthrum on a date between 6 and 12 May AD 878, soon resulting in the Treaty of Wedmore later the same year. The primary sources locate the battle at ""Ethandun"" or ""Ethandune"", and until a scholarly consensus identified its location with the present-day Edington in Wiltshire it was known as the Battle of "Ethandun", a name which continues to be used.
Treaty of York The Treaty of York was an agreement between the kings Henry III of England and Alexander II of Scotland, signed at York on 25 September 1237, which affirmed that Northumberland, Cumberland, and Westmorland were subject to English sovereignty. This established the Anglo-Scottish border in a form that remains almost unchanged to modern times (the only modifications have been regarding the Debatable Lands and Berwick-upon-Tweed). The treaty detailed the future status of several feudal properties and addressed other issues between the two kings, and historically marked the end of the Kingdom of Scotland's attempts to extend its frontier southward.
