Treaty of Newport
In September 1648, at the end of the
Second English Civil War, the
Long Parliament was concerned with the increasing radicalism in the
New Model Army. The Long Parliament began negotiations with King Charles I. The members wanted to restore the king to power, but wanted to limit the authority he had. Charles I conceded militia power, among other things, but he later admitted that “it was only so he could escape”.
 In November the negotiations began to fail, and the New Model Army seized power. Charles I was then taken into the Army’s custody, to await trial for treason.
