After several initial reverses, Ferdinand II had become more accommodating but as the Catholics turned things around and began to enjoy a long string of successes at arms he set forth the Edict of Restitution in 1629 in an attempt to restore the "status quo" of 1555 (Peace of Augsburg), vastly complicating the politics of settlement negotiations and prolonging the rest of the war. Encouraged by the mid-war successes, Ferdinand II became even more forceful, leading to infamies by his armies such as the Frankenburg Lottery ("Frankenburger Würfelspiel") (1625), suppression of the consequent Peasants' Revolt of 1626, and the Sack of Magdeburg (1631). Despite concluding the Peace of Prague (1635) with Saxony, and hence the internal, or civil, war with the Protestants, the war would drag on due to the intervention of many foreign states.
