The term "Austrian Wars" generally refers to a series of conflicts involving the Austrian Empire during the 18th and 19th centuries. Key wars include the War of the Austrian Succession (1740-1748) and the Austro-Prussian War (1866). These conflicts often involved major European powers, such as Prussia, France, and Great Britain, and were driven by territorial disputes and the balance of power in Europe. The War of the Austrian Succession began when Maria Theresa ascended to the throne, leading to challenges from rival nations. The Austro-Prussian War resulted in the defeat of Austria, significantly altering the political landscape of Germany and diminishing Austria's influence. These wars were pivotal in shaping modern Europe.
