The Treaty of Newcastle was a treaty signed between King Edward III of England and his puppet King Edward Balliol of Scotland on 12 June 1334.[1]
By the terms of the treaty, Balliol pledged the overlordship of England, the surrender of Berwick, and to cede the whole of south-eastern Scotland (Berwickshire, Roxburghshire, Selkirkshire, Peebleshire, Dumfrieshire, East Lothian, Mid Lothian and West Lothian) to England.
The treaty became null and void when the legal Crown of Scotland was restored.
