John (German: Johann; 12 December 1801 – 29 October 1873) was a King of Saxony and a member of the House of Wettin. John became King of Saxony after the death of his brother Frederick Augustus II on 9 August 1854. He exerted himself under influence of his minister Friedrich Ferdinand von Beust for the Great Germany Solution (de: Großdeutsche Lösung) of the imperial arrangement (under inclusion of Austria). In 1866 Saxony fought on the Austrian side in the Austro-Prussian War. Finally, after the defeat of the Battle of Königgrätz, Saxony joined the North German Confederation and in 1871 the German Empire under the hegemony of the Kingdom of Prussia. The King died two years later, aged seventy-one.
Beyond his political work, Johann was busy with literature. Under the pseudonym Philalethes he translated to German the Dante's Divine Comedy.
In Munich on 10 November 1822 (by proxy) and again in Dresden on 21 November 1822 (in person), Johann married with the Princess Amalia of Bavaria (Amalie Auguste), daughter of King Maximilian I Joseph of Bavaria. They had nine children.
