During the 1630s,
King Charles I, who was
king of both Scotland and England, had attempted religious reforms to the
Church of Scotland. In 1638, to express their strong political opposition to these reforms, many people throughout Scotland signed the
National Covenant. Supporters of this movement, known as
Covenanters, gained political supremacy in Scotland and mobilised forces to oppose any attempt by the King, or any of his
Royalist supporters in Scotland, to restore his authority. By June 1638, inconclusive skirmishing had taken place in the north-east of Scotland between Covenanters and Royalists. At the same time, Scottish and English armies had mustered on either side of their mutual border, near the town of
Berwick. == Negotiations and Terms ==
