King Alexander Ends War... with Cash
After years of conflict King Alexander III of Scotland and King Magnus IV of Norway settle their differences with cash. The Treaty of Perth is an oddly vague document that conveys title of the islands west of Scotland unconditionally to Scotland while Norway places conditions on the conveyance. It will all work out. The point is... peace.
The Shetland Isles to the north will not become part of Scotland until the mid-1400s when the King of Norway will pawn them to Scotland for a dowry of marriage and then "forget" to redeem them. It's all good.  
King Henry Lets Barons Buy Their Own Property
The last of the rebel Barons make peace with King Henry III of England. The King graciously allows the Barons to buy back their confiscated properties but the King has lost his momentum. The real power is with the future...his son, Prince Edward I.
