The continuity between Louis XVI’s reign and Napoleon’s is nationalistic feelings.
While Louis XVI faced challenges related to the emerging ideas of nationalism and the desire for a constitutional government, which were significant during the late 18th century, Napoleon capitalized on these nationalistic sentiments to establish his rule and expand France’s influence across Europe. Nationalism was a key driving force in both periods, even though the contexts and implications differed.
Other options, such as the desire for a constitution and the use of a ruling class based on titles, reflect more of a change rather than continuity, particularly with regards to Napoleon's establishment of a more meritocratic system compared to the traditional aristocracy of Louis XVI's reign.
