Emperor Napoleon abandoned plans to invade England and turned his armies against the Austro-Russian forces, defeating them at the Battle of Austerlitz on December 2, 1805. In 1806 Napoleon destroyed the Prussian army at Jena and Auerstädt and the Russian army at Friedland. He crowned his elder brother Joseph Bonaparte as King of Naples and Sicily in 1806 and converted the Dutch Republic into the kingdom of Holland for his brother Louis. Napoleon also established the Confederation of the Rhine (most of the German states) of which he was protector.
