Holy Roman Empress or Empress of the Holy Roman Empire is the title given to the consort (wife) or regent of the Holy Roman Emperor.
 The elective dignity of Holy Roman Emperor was restricted to males only, therefore there was never a Holy Roman Empress regnant, though women such as Theophanu or Maria Theresa of Austria, who controlled the power of rule, served as de facto Empresses regnant.
Archduke Maximilian Francis of Austria (full German name: Maximilian Franz Xaver Joseph Johann Anton de Paula Wenzel von Österreich, 8 December 1756 in Vienna – 26 July 1801 in Vienna) was Archbishop and Elector Spiritual of Cologne (and as such Chancellor of the Holy Roman Empire for Italy), and Grand Master of the Teutonic Knights.
 He was the youngest child of the Habsburg ruler of Austria, Maria Theresa, and her husband, Francis I, Holy Roman Emperor, for whom he was named.
 His siblings included Holy Roman Emperors Joseph II and Leopold II, Maria Carolina, Queen of Naples and Sicily, and Marie Antoinette, Queen of France and Navarre.
 He was the last fully functioning Elector of Cologne and was the employer and patron of the young Ludwig van Beethoven.

Francis II (German: "Franz" ; 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.
