ABSTRACT
The course of the Palatine crisis during 1621 reveals that Frederick's ardent attachment to his 'common cause' was the principal cause for the continuation of the Thirty Years' War at this early stage. During the year after the defeat at White Mountain, the main theater of war would transfer from Bohemia to the Palatinate, while Frederick's greatest concern would shift from trying to maintain Bohemia to defending his Palatine territories and dignities. Even after fleeing Prague, Frederick had no intention of ending the war against the enemies of the uprising. Immediately after leaving Prague he and his companions traveled first to the fortress-town of Glatz, in the mountain range along the Bohemian-Silesian border, where they could rest in safety until 15 November 1620. The Treaty of Mainz was signed on 12 April 1621 under the mediation of Landgrave Ludwig of Hessen-Darmstadt and the Elector of Mainz.
