The Protestant Union, also known as the Evangelical Union, is formally dissolved as per the demand of Holy Roman Emperor Ferdinand II.
The Protestant Union has been a coalition of Protestant German states. It was formed in 1608 for the defense of the rights, lands and person of each member state.
Ferdinand II imposes the Ban of the Empire on Protestant Union leader Frederick V of the Palatinate. This designation makes Frederick an "outlaw" in the literal sense: his is outside the protection of all laws, such that anyone can rob, injure, or kill him without any legal repercussions whatsoever.
The Protestant Union protests the actions of Holy Roman Emperor Ferdinand II, but he remains unmoved; eventually they submit and agree to disband their army.
