In this episode we watch England execute a king.  This is the strange tale of how England became a Protestant country, and why the Church of England is the way it is.  Along the way we watch militant Scottish Reformers challenge the power of the monarch, and uncover the roots of the Covenanters and Presbyterian churches.  The episode culminates in the English Civil War, as competing versions of church and state vie for the future of the nation.  Monarchy in Europe will never be the same again!
