Napoleonic Wars
Battle of Wagram, 6 July 1809, oil on canvas by Horace Vernet, 1836.
Austria’s decision to join the war against Napoleon in 1813 was driven by a strategic desire to establish a European balance of power rather than a simple desire to defeat France.12
Following Napoleon’s disastrous invasion of Russia in 1812, the Austrian foreign minister, Klemens von Metternich, sought to position Austria as an armed mediator. His primary goals were to:31
- Prevent Hegemony: Metternich feared that a total collapse of France would leave Europe at the mercy of Russia, just as he feared French dominance.12
- Secure Concessions: Through the Treaty of Reichenbach, Austria demanded that Napoleon dissolve the Confederation of the Rhine and return territories such as the Illyrian Provinces and the Duchy of Warsaw.34
- Gain Time: By dominating negotiations throughout the summer of 1813, Metternich used the period of "armed mediation" to secretly rearm the Austrian military.14
When Napoleon refused these peace terms, Austria formally declared war in August 1813, ultimately taking a leading role in the coalition to ensure a stable, multi-polar European order.142
