维也纳会议是从1814年9月18日到1815年6月9日之间在奥地利维也纳外交会议。本次会议由奥地利政治家克莱门斯·文策尔·冯·梅特涅主持，其目的在于解决由法国大革命战争和拿破仑战争导致的一系列关键问题，保证欧洲的长久和平。会议的目标不仅包括恢复战前国界，还包括重新调节各列强的权力，使他们能够相互平衡并保持和平。参会者主要是保守派，反对共和主义和革命。法国失去了在前一段时间征服的所有领土，而普鲁士、奥地利和俄罗斯则获得了大量的领土——普鲁士吞并了西部的一些德意志小国，并获得了40%的萨克森王国的领土；奥地利获得了威尼斯和北意大利的大部；俄罗斯则获得了波兰的一部分。在数月之前，荷兰王国被创建起来，并包括了部分过去的奥地利领土，这一部分领土于1830年成为比利时。

The Congress of Vienna (German: Wiener Kongress) was a conference of ambassadors of European states chaired by Austrian statesman Klemens Wenzel von Metternich, and held in Vienna from September 1814 to June 1815. The objective of the Congress was to provide a long-term peace plan for Europe by settling critical issues arising from the French Revolutionary Wars and the Napoleonic Wars. The goal was not simply to restore old boundaries but to resize the main powers so they could balance each other off and remain at peace. The leaders were conservatives with little use for republicanism or revolution. France lost all its recent conquests, while Prussia, Austria and Russia made major territorial gains. Prussia added smaller German states in the west and 40% of the Kingdom of Saxony; Austria gained Venice and much of northern Italy. Russia gained parts of Poland. The new Kingdom of the Netherlands had been created just months before, and included formerly Austrian territory that in 1830 became Belgium.
