How Prussia And Austria Challenged France

why did austria and prussia declare war on france

The French Revolutionary Wars, which lasted from 1792 until 1802, saw France pitted against several countries, including Austria and Prussia. The war was a result of the French Revolution, which had begun in 1789, and the subsequent flight of King Louis XVI and his wife, Marie Antoinette, from Paris in June 1791. The Declaration of Pillnitz, issued by Austria and Prussia in August 1791, expressed concern for the well-being of the King and Queen and threatened consequences if anything befell them. The French government interpreted this as a threat to its sovereignty and responded with provocations, ultimately leading to a French declaration of war on Austria in April 1792.

The Declaration of Pillnitz

The declaration stated:

> "They view the situation in which the King of France currently finds himself as a subject of common interest for all of Europe’s sovereigns."

It further called on these powers to:

> "Use the most efficient means…to place the King of France in a position to be totally free to consolidate the bases of a monarchical government."

The declaration also stated that Austria would go to war if and only if all the other major European powers also went to war with France. Leopold chose this wording so that he would not be forced to go to war, knowing that the British prime minister, William Pitt, did not support war with France. The declaration was intended to serve as a warning to the French revolutionaries to stop infringing on the king's prerogatives and to permit his resumption of power.

The French government largely interpreted it as a threat to its sovereignty, and a series of provocations ensued, culminating in France declaring war on Austria on 20 April 1792. The National Assembly of France interpreted the declaration to mean that Austria and Prussia were threatening the revolution, which radicalised the French revolutionaries and increased tensions.

French Revolution

The French Revolutionary Wars were a series of military conflicts resulting from the French Revolution that lasted from 1792 until 1802. The wars pitted France against Great Britain, Austria, Prussia, Russia, and several other countries. The key figure in the foreign reaction to the French Revolution was Holy Roman Emperor Leopold II, the brother of Queen Marie Antoinette of France. Leopold initially looked upon the revolution with equanimity but became more disturbed as the revolution became more radical. In 1791, Leopold and King Frederick William II of Prussia issued the Declaration of Pillnitz, which expressed concern for the well-being of King Louis XVI of France and his family and threatened consequences if anything should befall them. The French government, now acting without the king, interpreted this declaration as a threat to its sovereignty and responded with provocations that led to a French declaration of war on Austria in April 1792.

The French Revolution had a significant impact on the military forces of France, compromising and weakening them through revolutionary ideas and fostering poor discipline and insubordination in the ranks. This disorganization led to an unsuccessful initial invasion of the Austrian Netherlands, where French soldiers deserted and, in one case, murdered their general, Théobald Dillon. Despite these setbacks, France achieved several victories, including occupying Savoy and Nice, invading Germany, and winning the Battle of Jemappes against the Austrians.

The French Revolutionary Wars can be divided into two periods: the War of the First Coalition (1792–1797) and the War of the Second Coalition (1798–1802). During this time, France conquered territories in the Italian peninsula, the Low Countries, and the Rhineland through mass conscription of the vast French population. The spread of revolutionary principles over much of Europe was a significant outcome of these conflicts.

The execution of Louis XVI and Marie Antoinette was a pivotal event that mobilized Austria and Prussia against the French Revolution. The Declaration of Pillnitz, while intended as a diplomatic move to pressure the Revolution and caution its leaders, ultimately failed to prevent the escalation of tensions and the outbreak of war between France and the monarchies of Europe.

Austria's weak position

Political Factors:

  • The execution of Louis XVI and Marie Antoinette: The execution of the French monarch and his wife, who was the sister of Holy Roman Emperor Leopold II, left Austria with little choice but to mobilize against France. However, Leopold II initially intended the Pillnitz Declaration to be a diplomatic move without escalating to war.
  • Revolutionary France's Diplomacy: The revolutionaries leading France at the time were not seasoned diplomats. They interpreted the Pillnitz Declaration as an open declaration of war, whereas it was meant to caution the Revolution and support Louis XVI and Marie Antoinette.

Military Factors:

  • Disorganized Army: The French Revolution had thoroughly disorganized the army in the Austrian Netherlands, rendering them insufficient for an invasion.
  • Desertion and Mutiny: Following the declaration of war, French soldiers deserted en masse, and in one instance, they murdered their general, Théobald Dillon.
  • Successful French Campaigns: While the Prussians and Austrians assembled forces, the French made successful advances on multiple fronts. General Custine invaded Germany, reaching Frankfurt, and Dumouriez won a significant victory over the Austrians at the Battle of Jemappes, occupying the entire Austrian Netherlands by winter.

Economic Factors:

Agrarian Industries: During this period, the great powers, including Austria, relied primarily on agrarian industries, which may have limited their economic and military resources compared to trade-wealthy nations like Great Britain.

Prussia's coalition with Italy

Prussia's coalition with Russia and other powers against Napoleon's French Empire during the War of the Fourth Coalition (1806–1807) was a significant event in European history. Prussia, led by King Frederick William III, joined forces with Russia, Great Britain, Saxony, and Sweden to counter the growing power of Napoleon. Prussia's decision to join the coalition was influenced by its desire to maintain its status as the main power in Central Europe and its opposition to French dominance.

Prussia's involvement in the Fourth Coalition was preceded by its neutrality during the War of the Third Coalition (1805–1806). However, French diplomatic efforts, such as proposing Prussian occupation of Hanover, temporarily succeeded in keeping Prussia neutral. Despite this, Prussia's position was crucial for waging war against France, and its eventual participation became inevitable. Prussia's decision to join the Fourth Coalition was also influenced by its fear of the rise in French power after the defeat of Austria and the establishment of the French-sponsored Confederation of the Rhine.

Prussia's coalition with Russia and other powers in the Fourth Coalition led to significant military campaigns against Napoleon's forces. Prussia and Russia mobilized troops in Saxony and coordinated their strategies. The main conflicts between the coalition and France during this period included the Battle of Maida in southern Italy in July 1806, and the Battle of Austerlitz, which marked the end of the Third Coalition and the beginning of the Fourth.

The outcome of the Fourth Coalition was ultimately decided by the Treaties of Tilsit in July 1807, which brought peace between France and Russia. However, the terms of the treaty were harsh on Prussia, as Napoleon demanded significant territorial concessions. Despite the end of the Fourth Coalition, Britain remained at war with France, and Napoleon's invasion of Portugal later in 1807 reignited conflict in Continental Europe.

In subsequent conflicts, such as the War of the Sixth Coalition (1812–1814), Prussia continued to play a crucial role in the coalition against Napoleon. Prussia, along with Austria, Russia, the United Kingdom, Sweden, and other powers, defeated France and drove Napoleon into exile. The War of the Sixth Coalition saw significant battles, including Lützen, Bautzen, Dresden, and the Battle of Leipzig, the largest battle in European history before World War I.

War of the First Coalition

The War of the First Coalition was a series of military conflicts that took place between 1792 and 1797, during the French Revolution. It was fought between several loosely allied European powers and France, which had become a republic by the beginning of the war. The First Coalition included Austria, Prussia, Great Britain, the Dutch Republic, Spain, and several other countries.

The war was sparked by the French Revolution, which threatened the monarchies of Europe. The key figure in the initial foreign reaction to the French Revolution was Holy Roman Emperor Leopold II, brother of Queen Marie Antoinette of France. Leopold had looked on the revolution with calm but became more disturbed as it became more radical. On 27 August 1791, Leopold and King Frederick William II of Prussia issued the Declaration of Pillnitz, which expressed concern for the well-being of King Louis XVI of France and his family and threatened consequences if anything happened to them. The revolutionaries leading France at the time interpreted this as a declaration of war.

In April 1792, France went to war against a coalition of Austria, Prussia, and émigrés. France declared war on Austria on 20 April 1792, and Prussia, having allied with Austria in February, declared war on France in June 1792. An army composed mostly of Prussians joined the Austrian side and invaded France in July 1792. The French counterattacked with overwhelming numerical superiority and revolutionary zeal, pushing the Allied armies back.

By 1793, the French Republic was in dire straits, fending off enemy armies on all fronts. However, France introduced mass conscription, deploying more manpower than the other states. The French were successful on several fronts, occupying Savoy and Nice, invading Germany, and occupying several towns along the Rhine. In 1794, the French drove the Prussians back in the Rhineland, and by 1795, Prussia recognized French claims to the left bank of the Rhine in the Treaty of Basel, withdrawing from the war. The Coalition continued to unravel, and by 1796, only Britain remained at war with France. The War of the First Coalition ended in 1797 with the Treaty of Campo Formio, signed in October, after which Britain was the only nation still at war with France.
