Count Giuseppe Primoli was descended on his mother’s side from Lucien Bonaparte, Napoleon’s brother. Luciano was considered the founder of the “Roman branch” of the Bonapartes, in that he had established himself at Rome in 1805, when his disagreements with Napoleon forced him to retire from Paris and public life.
Giuseppe Primoli was born in Rome in 1851 from the marriage of Pietro Primoli to Carlotta Bonaparte.
The Napoleonic Museum occupies the ground floor of the Palazzo Primoli, which was built in the Seventeenth century; it originally belonged to the Gottifredi family- who according to the plan by Nolli plan still owned it in 1748 – then, at the end of the Eighteenth century, it passed to the Filonardi. Between 1820 and 1828 it was acquired by Count Luigi Primoli.
