King Louis XX is a hypothetical monarch often discussed in the context of the French royal family. He is considered a potential successor to the French throne, representing the House of Bourbon. The title is used by royalists who support the restoration of the monarchy in France. The idea of King Louis XX stems from the lineage of previous kings, particularly King Louis XVI, who was executed during the French Revolution. Supporters of the monarchy often look to current descendants, such as Louis Alphonse de Bourbon, who claims the title and advocates for royal traditions in modern France.
