Prince Murat in the context of "Charles XIV John of Sweden"

The Imperial House of France during the First French Empire was the family of Napoleon, including the House of Bonaparte, who held imperial titles as Emperor, Empress, Imperial Prince, or French Prince, and who were in the order of succession to the French imperial throne in accordance with the French constitution of 1804. According to Title III, Article 9 ("The Imperial Family"), "the members of the imperial family in the order of succession, bear the title of Princes of France (princes français)" and "the eldest son of the Emperor bears the title Prince Imperial (prince impérial)."

The non-Bonapartes who were members of the imperial family were Napoleon's uncle, brother-in-law and stepson of the families Fesch, Murat, and Beauharnais. This article lists their titles of the First French Empire; several held other titles in vassal states.

Joachim Murat (/mjʊəˈrɑː/ mure-AH, also /mʊˈrɑːt/ muurr-AHT; French: [ʒɔaʃɛ̃ myʁa]; Italian: Gioacchino Murat; 25 March 1767 – 13 October 1815) was a French Army officer and statesman who served during the French Revolutionary and Napoleonic Wars. Under the French Empire he received the military titles of Marshal of the Empire and Admiral of France. He was the first Prince Murat, Grand Duke of Berg from 1806 to 1808, and King of Naples as Joachim-Napoleon (Italian: Gioacchino Napoleone) from 1808 to 1815.

Born in Labastide-Fortunière in southwestern France, Murat briefly pursued a vocation in the clergy before enlisting in a cavalry regiment upon the outbreak of the French Revolution. Murat distinguished himself under the command of General Napoleon Bonaparte on 13 Vendémiaire (1795), when he seized a group of large cannons and was instrumental in suppressing the royalist insurrection in Paris. He became Napoleon's aide-de-camp and commanded the cavalry during the French campaigns in Italy and Egypt. Murat played a pivotal role in the Coup of 18 Brumaire (1799), which brought Napoleon to political power. In 1800 he married Caroline Bonaparte, thus becoming a brother-in-law to Napoleon.
