Short answers, pulled from the story.
Francis II was the last Holy Roman Emperor, ruling from 1792 to 1806, and the first Emperor of Austria as Francis I from 1804 to 1835. He was also King of Germany, Hungary, Croatia and Bohemia, and the first president of the German Confederation established in 1815.
Francis II was born on the 12th of February 1768 in Florence, the capital of Tuscany, where his father, the future Emperor Leopold II, ruled as Grand Duke. His mother was Maria Louisa of Spain, daughter of Charles III of Spain.
Francis II abdicated in 1806 after Napoleon created the Confederation of the Rhine and demanded he step down. He declared the bond tying him to the states of the Empire dissolved, which in effect ended the Holy Roman Empire, and continued to reign as Francis I, Emperor of Austria.
Francis II became Napoleon's father-in-law after his defeat in 1809, when he was forced to wed his daughter Marie-Louise to the French emperor. Francis had earlier assumed the title Emperor of Austria in 1804 in response to Napoleon crowning himself emperor of the French.
Francis II died on the 2nd of March 1835 in Vienna of a sudden fever at the age of 67, exactly 43 years and a day after his father's death. He was buried in tomb number 57 in the Imperial Crypt at Vienna's Neue Markt Square, surrounded by the tombs of his four wives, and was succeeded by his son Ferdinand I.
The anthem Gott erhalte Franz den Kaiser was composed in 1797 as the Kaiserhymne, with music by Joseph Haydn, to raise patriotic feeling during the war with France. The music survives today as the German national anthem, the Deutschlandlied.
