Franz Joseph I of Austria

Franz Joseph I or Francis Joseph I was Emperor of Austria, King of Hungary, and the ruler of the other states of the Habsburg monarchy from 1848 until his death in 1916. In the early part of his reign, his realms and territories were referred to as the Austrian Empire, but were reconstituted as the dual monarchy of Austria-Hungary in 1867. From 1 May 1850 to 24 August 1866, he was also president of the German Confederation.

In December 1848, Franz Joseph's uncle Emperor Ferdinand I abdicated the throne at Olomouc, as part of Minister President Felix zu Schwarzenberg's plan to end the Hungarian Revolution of 1848. Franz Joseph then acceded to the throne. In 1854, he married his first cousin Duchess Elisabeth in Bavaria, with whom he had four children: Sophie, Gisela, Rudolf, and Marie Valerie.
