A treaty on February 23rd 1573 was agreed at a Privy Council meeting in Perth.
The Pacification of Perth brought an end to the war between the Roman Catholic supporters of Mary, Queen of Scots and the Protestant Lords who had forced her 1567 abdication in favour of her son King James VI.
The peace was facilitated by an English envoy, Henry Killigrew, and the principal parties to the agreement were James Douglas, 4th Earl of Morton and Archibald Campbell, 5th Earl of Argyll , who were the principal Protestant Lords, and Mary’s supporters George Gordon, 5th Earl of Huntly, the Hamiltons, and other Catholic nobles. Mary’s supporters agreed to recognise Morton as Regent and end their fight in return for a full pardon and return of their lands.
The peace ended any possibility of Mary regaining the Scottish throne and reinforced the position of the Post-Reformation Protestant Church.
