Francis II, Holy Roman Emperor
Francis II (; 12 February 1768 – 2 March 1835) was the last Holy Roman Emperor, ruling from 1792 until 6 August 1806, when he dissolved the Holy Roman Empire of the German Nation after the decisive defeat at the hands of the First French Empire led by Napoleon at the Battle of Austerlitz. In 1804, he had founded the Austrian Empire and became Francis I, the first Emperor of Austria, ruling from 1804 to 1835, so later he was named the one and only "Doppelkaiser" (double emperor) in history.
For the two years between 1804 and 1806, Francis used the title and style "by the Grace of God elected Roman Emperor, ever Augustus, hereditary Emperor of Austria" and he was called the "Emperor of both the Holy Roman Empire and Austria". He was also Apostolic King of Hungary and Bohemia as Francis I. He also served as the first president of the German Confederation following its establishment in 1815.
Otto III, Holy Roman Emperor
On 14 July 982, Otto II's army suffered a crushing defeat against the Muslim Emirate of Sicily at the Battle of Stilo. Otto II had been campaigning in southern Italy with hopes of annexing the whole of Italy into the Holy Roman Empire. Otto II himself escaped the battle unharmed but many important imperial officials were among the battle's casualties. Following the defeat and at the insistence of the Empire's nobles, Otto II called an assembly of the Imperial Diet in Verona at Pentecost, 983, where he proposed to the assembly to have the three-year-old Otto III elected as King of Germany, becoming Otto II's undoubted heir apparent. This was the first time a German ruler had been elected on Italian soil. After the assembly was concluded, Otto III and his mother Theophanu traveled across the Alps in order for Otto to be crowned at Aix, the traditional location of the coronation of the German kings. Otto II stayed behind to address military action against the Muslims. While still in central Italy, however, Otto II suddenly died on 7 November 983, and was buried in St. Peter's Basilica in Rome.
