Letters and Files on the History of the Thirty Years' War. The Politics of Maximilian of Bavaria and His Allies, 1618 – 1651.

1631年是三十年战争历史上的一个分水岭，甚至可能是最决定性的时刻。对于巴伐利亚州的当选王子马克西米利安一世来说，情况尤其如此。这一版本从1630年秋天开始，毫无疑问，马西米利安处于权力的巅峰：他不仅是王子的选举人，还领导着联盟。在前一年举行的帝王食谱中，他成功地强行通过了核心政治目标。尤其是在巴伐利亚施加的压力下，费迪南德二世皇帝发现自己被迫解除了阿尔布雷希特·冯·瓦伦斯坦的帝国军队最高指挥官职务。接替他的是联盟的主要将领，蒂利伯爵约翰·瑟克雷夫斯，现在他也被任命为帝国军队的负责人。除了这一特许权(对帝国的地产和王子选举人)，维也纳政府无法制定更具体的计划，将皇帝的儿子费迪南德确立为罗马皇帝。尽管马克西米利安刚刚加入选举团，但他在议会中扮演着关键人物的角色，并确立了自己作为哈布斯堡王室自由主义的真正对立面和捍卫者的地位。然而，在1632年初，局势完全扭转了：瑞典在布雷登菲尔德的胜利(1631年9月18日)彻底推翻了先前的权力关系。这一新发展的主要输家是巴伐利亚州的马克西米利安和他的联盟。他们再也无法从这一转折中恢复过来。1635年布拉格和平联盟的终结标志着1631年开始的一项发展的合乎逻辑的结束，这一发展伴随着所有的政治和军事变化。考虑到1631年的分水岭年S的重要意义，有理由将今年的政治和军事发展作为一个全面版本的主题，广泛地讨论帝国、巴伐利亚和联盟的影响。这一源代码版本执行的基础研究非常重要的未来研究人员处理它的所有方面的三十年战争。

The year of 1631 represents a watershed, perhaps even the most decisive moment, in the history of the Thirty Years' War. This is especially true for Prince-Elector Maximilian I of Bavaria. This edition begins with the fall of 1630, a time that no doubt saw Maximilian at the height of his power: as well as being prince-elector, he also headed the League. At the imperial diet that had taken place the year before, he had managed to force through central political goals. Especially due to pressure exerted by Bavaria, Emperor Ferdinand II found himself forced to dismiss Albrecht von Wallenstein as supreme commander of the imperial forces. He was replaced by the League's leading general, Johann T'Serclaes Count of Tilly, who was now also put in charge of the empire's army. Apart from this concession (to the empire's estates and prince-electors), the Vienna government was unable to make the plans to establish Ferdinand, the emperor's son, as the Roman emperor more concrete. Despite just having joined the electoral college, Maximilian acted as a key figure within this council and established himself as Habsburg's actual antipode and defender of princely freedoms.In the beginning of 1632, however, the tables had completely turned: The Swedish victory at Breitenfeld (September 18, 1631) had completey overturned prior power relations. The main losers of this new development were Maximilian of Bavaria and his League. They were never to recover from this turn of events. The League's termination by the Peace of Prague of 1635 marked the logical conclusion of a development which began in the year of 1631 with all its political and military alterations.Considering the 'watershed year of 1631's' significance, it is more than justified to make the political and military developments of this year subject of a comprehensive edition that deals extensively with the ramifications for the empire, Bavaria, and the League. This source edition performs fundamental research of great importance to future researchers dealing with the Thirty Years' War in all its dimensions.
