All Swedish resistance in the south of…

All Swedish resistance in the south of Germany had ended by the spring of 1635.

After that, the two sides meet for negotiations, producing the Peace of Prague (1635), which entail a delay in the enforcement of the Edict of Restitution for 40 years and allows Protestant rulers to retain secularized bishoprics held by them in 1627.

This protects the Lutheran rulers of northeastern Germany, but not those of the south and west (whose lands had been occupied by the Imperial or League armies prior to 1627).

Negotiations towards the agreement had been instigated by the Elector of Saxony, John George, who whilst being a Lutheran prince had nonetheless been an ally of the Emperor until the Swedish intervention in 1630.

Years of fighting, an inability to reimpose Roman Catholicism by force, and the need to put an end to the intervention of foreign powers in German affairs all combine to bring Ferdinand to the table with a degree of willingness to make concessions towards the Lutheran princes.

Calvinist Brandenburg is reluctant to sign, since besides the announced annulment of the Edict of Restitution, toleration of Calvinism is not mentioned.

To get Brandenburg to sign up, Sweden and Ferdinand promise her the succession in the Duchy of Pomerania in return.
