Gueniffey collaborated on the Critical Dictionary of the French Revolution, directed by Furet and Mona Ozouf in 1988. He published monographs dedicated to elections in the revolutionary period and to the Reign of Terror. Moving into the Napoleonic era, he edited the critical re-editions of Jacques Bainville's biography of Napoleon and the Napoleonic memoirs of Jean-Antoine Chaptal, and published a monograph dedicated to the Coup of 18 Brumaire. In 2013, he published Bonaparte, the first of a two-volume work on Napoleon, also published in English, which received acclaim from critics.[4][5][6]
Gueniffey, writing in Le Point magazine, criticized the 2023 film Napoleon as rewriting history in a "very anti-French and very pro-British" manner.[7]
