1792 — War of the First Coalition

The War of the First Coalition (French: Guerre de la première coalition) was a set of wars between a coalition of several European powers and France fought from 1792 to 1797. The coalition was only loosely allied and fought without much coordination; each power wanted to annex a different part of France should they defeat the French, something that never occurred. Relations between the French revolutionaries and neighbouring monarchies had deteriorated following the Declaration of Pillnitz in August 1791. Eight months later, following a vote by the revolutionary-led Legislative Assembly, France declared war on Austria on 20 April 1792; Prussia, having allied with Austria in February, declared war on France in June 1792.
