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.
Leopold I, Holy Roman Emperor
Hungary elected Leopold as its king in 1655, with Bohemia and Croatia following suit in 1656 and 1657 respectively. In July 1658, more than a year after his father's death, Leopold was elected Emperor at Frankfurt in spite of the French minister, Cardinal Mazarin, who sought to put the Imperial Crown on the head of Ferdinand Maria, Elector of Bavaria, or some other non-Habsburg prince. To conciliate France, which had considerable influence in German affairs thanks to the League of the Rhine, the newly elected Emperor promised not to assist Spain, then at war with France. This marked the beginning of a nearly 47-year career filled with rivalry with France and its king, Louis XIV. The latter's dominant personality and power completely overshadowed Leopold, even to this day, but though Leopold did not lead his troops in person as Louis XIV did, he was no less a warrior-king given the greater part of his public life was directed towards the arrangement and prosecution of wars.
