Between 1849 and 1866 the struggle for leadership of the German Confederation moved from diplomatic manoeuvres and revolutionary aftershocks to open war. This article explains the key turning points in the rivalry between Prussia and Austria, the role of Bismarck, and the consequences of the Austro-Prussian War for German unification. It is designed as a focused revision guide for Edexcel A-Level History.
1849 年至 1866 年间，围绕德意志邦联领导权的争夺从外交博弈和革命余波逐步发展为公开战争。本文梳理普鲁士与奥地利争霸的关键转折点、俾斯麦的作用，以及普奥战争对德意志统一的影响，可作为 Edexcel A-Level 历史的专题复习指南。
1. The Post-1848 Settlement | 1848 年后格局
The revolutions of 1848–49 failed to produce a unified German nation-state, but they left the rivalry between Prussia and Austria sharper than before. Austria restored the old German Confederation (Deutscher Bund) under its presidency, while Prussia sought to exploit nationalist sentiment to build an alternative union under its own leadership. The two powers therefore began the 1850s with competing blueprints for Germany: Austria favoured a loose confederation of sovereign princes, whereas Prussia increasingly presented itself as the champion of a stronger German nation.
1848–49 年革命未能建立统一的德意志民族国家，却使普鲁士与奥地利的竞争更加尖锐。奥地利恢复了由其担任主席的旧德意志邦联，而普鲁士则试图利用民族主义情绪，在自己的领导下建立一个替代性联盟。因此，进入 1850 年代时，两国对德国的未来蓝图截然不同：奥地利主张松散的君主邦联，普鲁士则日益以德意志民族强有力代言人的姿态出现。
2. Prussia’s Erfurt Union and the Humiliation of Olmütz | 普鲁士埃尔福特联盟与奥尔米茨之辱
In 1849–50 Prussia attempted to create a Prussian-led Erfurt Union of German states, excluding Austria. Austria, once it had suppressed its own domestic revolts, demanded the restoration of the old Confederation and secured Russian backing. Under the Punctation of Olmütz in November 1850, Prussia abandoned the Erfurt Union and accepted Austrian leadership of the revived Confederation. This diplomatic defeat humiliated Prussia and exposed the limits of its power, but it also encouraged Prussian conservatives and later Bismarck to plan for a decisive reckoning with Austria.
1849–50 年，普鲁士试图建立一个由它领导、排除奥地利的德意志国家联盟，即埃尔福特联盟。奥地利在镇压国内起义后，要求恢复旧邦联，并得到俄国的支持。1850 年 11 月《奥尔米茨条约》签订，普鲁士放弃埃尔福特联盟，接受奥地利对恢复后邦联的领导权。这场外交失败使普鲁士蒙羞，暴露了其实力限度，但也促使普鲁士保守派以及后来的俾斯麦筹划与奥地利进行决定性清算。
3. The Crimean War and Austrian Isolation | 克里米亚战争与奥地利的孤立
The Crimean War (1853–56) weakened Austria’s international position. Austria refused to join Britain and France against Russia, but also refused to support Russia, instead occupying the Danubian Principalities. This policy alienated both sides: Russia felt betrayed by its former ally, while the Western powers distrusted Austria’s neutrality. As a result, by 1856 Austria was diplomatically isolated. This isolation was crucial later because in 1866 Bismarck was able to keep Russia and France neutral while Prussia fought Austria.
克里米亚战争（1853–56 年）削弱了奥地利的国际地位。奥地利既没有加入英法对俄作战，也没有支持俄国，而是占领了多瑙河两公国。这种政策两头不讨好：俄国感到被昔日盟友背叛，西方列强也不信任奥地利的中立。结果到 1856 年，奥地利在外交上陷入孤立。这种孤立后来十分关键，因为 1866 年俾斯麦得以在普鲁士对奥作战时保持俄国和法国中立。
4. The Italian War of 1859 | 1859 年意大利战争
In 1859 Austria fought Piedmont and France in northern Italy and was defeated at Magenta and Solferino, losing Lombardy. The war revealed the weakness of Austria’s army and finances, and it encouraged nationalists across Germany to look to Prussia for leadership. Prussia mobilised but did not intervene decisively, which angered both Austria and German liberals. The 1859 crisis deepened the Austro-Prussian rivalry and strengthened the argument inside Prussia that military reform was urgently needed if Prussia were to challenge Austria successfully.
1859 年，奥地利在意大利北部与皮埃蒙特和法国交战，在马真塔和索尔费里诺战败，丧失伦巴第。这场战争暴露了奥地利军队和财政的虚弱，也鼓舞了德意志各地的民族主义者，使他们寄望于普鲁士的领导。普鲁士虽进行了动员，却未果断介入，这激怒了奥地利和德意志自由派。1859 年危机加深了普奥对立，也使普鲁士内部更加确信：若要成功挑战奥地利，军事改革刻不容缓。
5. The Prussian Constitutional Conflict and Bismarck’s Appointment | 普鲁士宪法冲突与俾斯麦上台
In the early 1860s Prussia’s King Wilhelm I demanded an army reform that would increase the size of the regular army and extend service. The liberal-dominated Landtag refused to approve the necessary taxes, causing a constitutional conflict over who controlled the military budget. In September 1862 Wilhelm appointed Otto von Bismarck as Minister President. Bismarck defied the liberal majority, collecting taxes without parliamentary approval and using the army reform as a tool for Prussia’s eventual struggle against Austria. His words that the great questions of the day would be decided by “blood and iron” signalled a new direction.
1860 年代初，普鲁士国王威廉一世要求进行军事改革，扩大常备军并延长服役期。由自由派主导的邦议会拒绝批准相关税收，引发了一场围绕军事预算控制权的宪法冲突。1862 年 9 月，威廉任命奥托·冯·俾斯麦为首相。俾斯麦无视自由派多数，未经议会批准征税，并把军事改革作为普鲁士最终对奥斗争的工具。他所说的当代重大问题须由“铁与血”决定，标志着一个新方向的开始。
6. The Danish War of 1864 | 1864 年丹麦战争
The Schleswig-Holstein question provided Bismarck with an opportunity to weaken Austria and strengthen Prussia. In 1864 Prussia and Austria jointly defeated Denmark after a dispute over the duchies of Schleswig, Holstein and Lauenburg. By the Treaty of Vienna the duchies were ceded to Prussia and Austria jointly. The joint administration created immediate friction: Prussia wanted to annex the duchies, while Austria preferred an independent duke. Bismarck deliberately used the condominium to provoke disputes with Austria and to present Prussia as the natural protector of German interests in the north.
石勒苏益格—荷尔斯泰因问题为俾斯麦提供了削弱奥地利、增强普鲁士的机会。1864 年，普鲁士与奥地利因石勒苏益格、荷尔斯泰因和劳恩堡公国的争端联合击败丹麦。根据《维也纳和约》，这些公国由普奥共同割让和共管。共管体制立即产生摩擦：普鲁士想吞并公国，奥地利则倾向于设立一位独立公爵。俾斯麦蓄意利用共管安排制造与奥地利的争端，并将普鲁士塑造成德意志北方利益的天然保护者。
7. The Gastein Convention | 《加施泰因公约》
In August 1865 Prussia and Austria signed the Convention of Gastein, which divided the administration of the duchies: Prussia governed Schleswig while Austria administered Holstein. The arrangement was a temporary compromise rather than a settlement. Bismarck calculated that the awkward geographical separation and Austria’s distance from Holstein would lead to fresh conflicts. He also used the Convention to test whether Austria could be provoked into breaking the agreement, giving Prussia a pretext for war. Far from easing tension, Gastein prepared the ground for the final showdown.
1865 年 8 月，普奥签署《加施泰因公约》，分割两公国的行政权：普鲁士管辖石勒苏益格，奥地利管辖荷尔斯泰因。这一安排只是临时妥协，并非根本解决。俾斯麦预料到地理上的不便分隔以及奥地利与荷尔斯泰因相距遥远会引发新的冲突。他还利用该公约试探奥地利能否被激怒而破坏协议，从而为普鲁士提供开战借口。《加施泰因公约》非但没有缓和紧张，反而为最后摊牌做了准备。
8. Bismarck’s Diplomatic Isolation of Austria | 俾斯麦对奥地利的外交孤立
Before moving against Austria, Bismarck secured Prussia’s diplomatic flanks. He maintained good relations with Russia because of Prussia’s earlier support during the Polish revolt of 1863. He met Napoleon III at Biarritz in October 1865 and hinted at compensations on the Rhine, keeping France neutral. In April 1866 Bismarck signed a secret alliance with Italy, promising Venetia to Italy if it attacked Austria from the south. These moves ensured that in the summer of 1866 Austria would face Prussia on one front and Italy on another, without reliable allies among the great powers.
在对奥地利动手之前，俾斯麦巩固了普鲁士的外交侧翼。由于普鲁士在 1863 年波兰起义期间支持俄国，他得以维持与俄国的良好关系。1865 年 10 月，他在比亚里茨会见拿破仑三世，暗示在莱茵河地区给予补偿，使法国保持中立。1866 年 4 月，俾斯麦与意大利签订秘密同盟，承诺只要意大利从南方进攻奥地利，便可获得威尼西亚。这些举措确保到 1866 年夏天，奥地利将面临南北两线作战，且在大国中没有可靠盟友。
9. The Austro-Prussian War and Königgrätz | 普奥战争与克尼格雷茨战役
War broke out in June 1866 after Bismarck accused Austria of violating the Gastein Convention over Holstein and ordered Prussian troops into the duchy. Prussia quickly defeated Austria’s German allies, including Hanover and Saxony, and used railways, breech-loading rifles and better staff planning to outmanoeuvre the Austrian army. On 3 July 1866 the decisive Battle of Königgrätz (Sadowa) ended in a crushing Austrian defeat. The battle demonstrated the superiority of Prussian military organisation and confirmed Bismarck’s policy of solving the German question by force under Prussian leadership.
1866 年 6 月，俾斯麦指责奥地利在荷尔斯泰因违反了《加施泰因公约》，随后命令普军进入该公国，战争爆发。普鲁士迅速击败奥地利的德意志盟友，包括汉诺威和萨克森，并利用铁路、后装步枪和更优秀的参谋计划机动包抄奥军。1866 年 7 月 3 日，决定性的克尼格雷茨（萨多瓦）战役以奥地利的惨败告终。这场战役显示了普鲁士军事组织的优越性，也印证了俾斯麦以武力在普鲁士领导下解决德意志问题的政策。
10. The Peace of Prague and the North German Confederation | 布拉格和约与北德意志邦联
The Peace of Prague, signed in August 1866, dissolved the old German Confederation and excluded Austria from German affairs. Prussia annexed Schleswig-Holstein, Hanover, Hesse-Kassel, Nassau and Frankfurt, and established the North German Confederation under its leadership in 1867. Austria lost no territory to Prussia except Venetia, which was ceded to Italy, but its supremacy in Germany was ended. The settlement created a Prussian-dominated northern Germany and left the southern German states outside the Confederation, setting the stage for the final phase of unification after 1870.
1866 年 8 月签订的《布拉格和约》解散了旧德意志邦联，并将奥地利排除出德意志事务。普鲁士吞并了石勒苏益格—荷尔斯泰因、汉诺威、黑森—卡塞尔、拿骚和法兰克福，并于 1867 年建立了由其主导的北德意志邦联。除威尼西亚割让给意大利外，奥地利未向普鲁士失去领土，但其在德意志的霸权就此终结。这一安排形成了普鲁士主导的北德意志，南部诸邦仍留在邦联之外，为 1870 年后统一的最后阶段奠定了基础。
11. Historiographical Debate: Bismarck, Austria or Structural Forces? | 史学争论：俾斯麦、奥地利还是结构性力量？
Historians have debated the reasons for Prussia’s victory and Austria’s defeat. The traditional Borussian interpretation presents Bismarck as a master planner who deliberately steered events toward Prussian hegemony. Revisionist historians stress that Austria faced structural weaknesses: its multi-ethnic empire, financial crises, weaker military reform and diplomatic isolation. Modern scholarship also emphasises economic factors, especially the Zollverein and Prussian industrial growth, which gave Prussia the resources and modern infrastructure that underpinned its military success. In exam answers, it is important to balance these interpretations rather than attributing the outcome solely to Bismarck’s genius.
历史学家对普鲁士胜利、奥地利失败的原因存在争论。传统普鲁士学派把俾斯麦描绘成有意将局势引向普鲁士霸权的规划大师。修正派史家则强调奥地利面临结构性弱点：多民族帝国、财政危机、军事改革滞后和外交孤立。现代研究还重视经济因素，尤其是关税同盟和普鲁士工业增长，正是它们为普鲁士提供了支撑军事成功的资源和现代基础设施。在考试答案中，应平衡这些解释，而不是把结果完全归因于俾斯麦的个人天才。
