Second Silesian War was the 1744–1745 phase of Prussia’s expansionist conflicts over Silesia that followed the First Silesian War and formed part of the wider War of the Austrian Succession. The war featured decisive campaigns by Frederick II of Prussia against Habsburg forces led by Maria Theresa and her generals, culminating in the Treaty of Dresden which confirmed Prussian control of Silesia. It reshaped Central European alliances involving the Kingdom of Great Britain, Kingdom of France, Kingdom of Saxony, and the Russian Empire.

Background and Causes

The conflict arose from dynastic and territorial disputes tied to the War of the Austrian Succession, when Prussia seized Silesia from the Habsburg Monarchy in the First Silesian War. Frederick II’s claim rested on earlier succession crises affecting the House of Hohenzollern and pressures from rival courts such as Versailles and Vienna. Maria Theresa’s attempts to recover Silesia intersected with diplomatic maneuvering by Charles VII, Holy Roman Emperor allies and the shifting alignments of the Quadruple Alliance (1745-1748) precursors. Economic value of Silesian mines and manufactories, strategic positions along the Oder River and border fortresses like Glogau intensified rivalry among the Kingdom of Prussia, Habsburg Monarchy, Kingdom of France, and Kingdom of Great Britain.

Belligerents and Commanders

Prussian forces were commanded personally by Frederick II of Prussia, assisted by generals including Hans Joachim von Zieten and Friedrich Wilhelm von Seydlitz, with youth officers from the House of Hohenzollern training under their aegis. The Habsburg side operated under the political leadership of Maria Theresa and field commanders such as Prince Charles of Lorraine and Count Otto Ferdinand von Traun, with Austrian regiments drawn from the Imperial Army and regional contingents from Kingdom of Hungary crownlands. External powers influenced operations: the Kingdom of France provided diplomatic support to Austrian rivals, while Great Britain and the Dutch Republic engaged in coalition politics and subsidy arrangements affecting logistics and command choices. Regional states like the Electorate of Saxony, Electorate of Bavaria, and principalities of the Holy Roman Empire furnished troops or defensive positions relevant to campaign planning.

Campaigns and Major Battles

Frederick II initiated a rapid advance into Bohemia in 1744, seizing fortified positions and seeking decisive engagement with Habsburg armies concentrated around Prague and the Bohemian plain. Key operations included sieges and maneuvers at fortified locations such as Brno and river crossings on the Elbe. The campaign’s notable pitched engagement was the Battle of Hohenfriedberg (1745), where Prussian cavalry under commanders like Friedrich Wilhelm von Seydlitz executed a decisive charge that routed Austrian infantry and cavalry commanded by leaders from the Imperial Army and allied contingents. Other significant encounters occurred at the campaigns near Soor (battle) and in operations opposing the Prince of Waldeck and the Electorate of Hanover contingents in Saxony. Siege warfare, winter maneuvers, and coordinated offensives shaped outcomes, with Prussian tactical innovations in infantry drill and cavalry shock tactics overcoming larger Habsburg formations despite attrition and supply challenges.

Diplomacy and International Context

Diplomatic efforts during the war reflected the broader Diplomatic Revolution tendencies that later crystallized in alignments like the Seven Years' War. Britain’s interest in checking French influence and preserving balance led to subsidies and political pressure from London on allies, while Versailles sought to exploit Habsburg vulnerabilities by supporting anti-Habsburg coalitions. The Imperial Diet and German princes such as the Electorate of Saxony engaged in negotiations mediated by envoys from Vienna, Paris, and The Hague. The Treaty of Dresden negotiations involved envoys representing Maria Theresa, Frederick II, and intermediaries from Great Britain and the Dutch Republic, with outcomes influenced by simultaneous frontier pressures from the Ottoman Empire and the fiscal strains on the Habsburg Monarchy.

Aftermath and Consequences

The war ended with the Treaty of Dresden (1745), which confirmed Prussian possession of Silesia and solidified Frederick II’s status as a major European monarch. The settlement deepened rivalries between the House of Hohenzollern and the Habsburg Monarchy, contributing to the later realignments of the Diplomatic Revolution and the Seven Years' War. Military lessons from Prussian victories influenced reforms in the Prussian Army and prompted Austrian military and administrative changes under Maria Theresa and advisors like Count von Zinzendorf and Field Marshal von Neipperg. Politically, control of Silesia enhanced Prussian fiscal resources and industrial capacity, affecting the balance among Central European states including the Electorate of Saxony, Kingdom of Poland, and the Russian Empire. The war’s legacy persisted in 18th-century treaties, frontier demarcations, and the evolution of European diplomacy that set precedents for later continental conflicts.
