Holy Roman Emperor Ferdinand II and Elector John George of Saxony sign the Peace of Prague. Saxony gains the greatest concessions, acquiring the territory of Lusatia, and securing the archbishopric of Magdeburg for the Elector's second son. The treaty agrees to return the Holy Roman Empire to its state in 1627, before the 1629 Edict of Restitution, and Lutheranism takes on a privileged status. The treaty is subsequently accepted by Brandenburg and most Lutheran states, so from henceforth the Thirty Years War shifts away from a religious conflict towards an international one, with France and Sweden allied against the House of Habsburg.
