Franz Joseph I of Austria
Franz Joseph I or Francis Joseph I (Franz Joseph Karl; 18 August 1830 – 21 November 1916) was Emperor of Austria, King of Hungary, and monarch of many other states of the Austro-Hungarian Empire, from 2 December 1848 to his death. From 1 May 1850 to 24 August 1866 he was also President of the German Confederation. He was the longest-reigning Emperor of Austria and King of Hungary, as well as the third-longest-reigning monarch of any country in European history, after Louis XIV of France and Johann II of Liechtenstein.
Hungarian Revolution of 1848
After the Austrian revolution in Vienna was defeated, Franz Joseph I of Austria replaced his uncle Ferdinand I of Austria, who was not of sound mind. Franz Joseph didn't recognise Batthyány's second premiership, which began on 25 September. Also, Franz Joseph was not recognized as "King of Hungary" by the Hungarian parliament, and he was not crowned as "King of Hungary" until 1867. In the end, the final break between Vienna and Pest occurred when Field-Marshal Count Franz Philipp von Lamberg was given control of every army in Hungary (including Jelačić's). He went to Hungary where he was mobbed and viciously murdered. Following his murder the Imperial court dissolved the Hungarian Diet and appointed Jelačić as Regent.
