A rare work (only held by one library worldwide) that contains prayers of the Jewish community in Vienna thanking G-d for the victory and return of Franz I.

Francis II, Holy Roman Emperor (German language: Franz II, Heiliger Römischer Kaiser) (Florence, 12 February 1768 – Vienna, 2 March 1835) was the last Holy Roman Emperor, ruling from 1792 until 6 August 1806, when he dissolved the Empire after the disastrous defeat of the Third Coalition by Napoleon at the Battle of Austerlitz. In 1804 he founded the Austrian Empire and became Francis I of Austria (Franz 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, always August, hereditary Emperor of Austria and he was called the Emperor of both Germany and Austria. Francis I continued his leading role as an opponent of Napoleonic France in the Napoleonic Wars, and suffered several more defeats after Austerlitz, the most severe of which led to his delivering his daughter, Marie Louise of Austria, as a bride in a reluctant marriage of state. Francis was a son of Emperor Leopold II (1747 – 1792) and his wife Maria Luisa of Spain (1745 – 1792, daughter of Charles III of Spain.
