Why did France go to war with Austria in 1792?
The King and the Girondins specifically wanted to wage war. The King expected war would increase his personal popularity; he also foresaw an opportunity to exploit any defeat: either result would make him stronger. The Girondins wanted to export the Revolution throughout Europe and, by extension, to defend the Revolution within France. Only some of the radical Jacobins opposed war, preferring to consolidate and expand the Revolution at home. The Austrian emperor Leopold II, brother of Marie Antoinette, may have wished to avoid war, but he died on 1 March 1792. France declared war on Austria on 20 April 1792.
