Catholic and Protestant Leagues begin to form in the German States
to carry out the terms of the 1648 Peace of Westphalia. The
Catholic League of Frankfort is made up of the three ecclesiastical
electors, the Count Palatine and the Bishop of Münster, and is
later joined by the Circles of Swabia, Franconia and Lower Saxony.
The Protestant League comprises Queen Christina of Sweden, the
Landgravine of Hesse, and the Dukes of Brunswick and Luxembourg.
