The Battle of Königgrätz (or Battle of Sadová; Czech: Bitva u Hradce Králové) was the decisive battle of the Austro-Prussian War in which the Kingdom of Prussia defeated the Austrian Empire. It took place on 3 July 1866, near the Bohemian city of Hradec Králové (German: Königgrätz) and village of Sadová, now in the Czech Republic. It was the single largest battle of the war, and the largest battle in the world since the Battle of Leipzig in 1813.
