Lucien Bonaparte (the 21st of May 1775 - the 29th of June 1840) was a French politician and diplomat and the younger brother of Napoleon Bonaparte. He served as president of the Council of Five Hundred in 1799 and as Minister of the Interior from December 1799 to November 1800.
As president of the Council of Five Hundred, Lucien Bonaparte was one of the principal architects of the Coup of 18 Brumaire in November 1799. He had pamphlets distributed in Paris describing a fabricated Jacobin plot to justify relocating the legislature to Saint-Cloud, then kept the assembly in session until Napoleon arrived with soldiers. He arranged Napoleon's formal election as First Consul the following day.
Lucien Bonaparte broke with Napoleon in 1804 over Napoleon's intention to declare himself Emperor of the French and his demand that Lucien divorce his wife Alexandrine de Bleschamp and marry the Queen of Etruria, a Bourbon Spanish princess. Lucien refused both demands, rejected all imperial honors, and went into self-imposed exile in Rome.
Lucien Bonaparte was captured in 1810 when he attempted to flee to the United States from his Italian estates. The British frigate HMS Pomone intercepted his ship. He was subsequently allowed to settle in England, first at Ludlow and later at Thorngrove House in Grimley, Worcestershire.
Lucien Bonaparte conducted excavations at his estate in Frascati, producing a complete statue of Tiberius, and at Musignano, where he found a bust of Juno.

Lucien Bonaparte died on the 29th of June 1840 in Viterbo, in the Papal States, from stomach cancer, the same disease that had killed his father and reportedly his brother Napoleon. At his death he held the title of Prince Buonaparte, granted by Pope Gregory XVI on the 16th of April 1837.
