Louis XVII in the context of French Constitution of 1791

Louis XVIII (Louis Stanislas Xavier; 17 November 1755 – 16 September 1824), known as the Desired (French: le Désiré), was King of France from 1814 to 1824, except for a brief interruption during the Hundred Days in 1815. Before his reign, he spent 23 years in exile from France beginning in 1791, during the French Revolution and the First French Empire.

Until his accession to the throne of France, he held the title of Count of Provence as brother of King Louis XVI, the last king of the Ancien Régime. On 21 September 1792, the National Convention abolished the monarchy and deposed Louis XVI, who was later executed by guillotine. When his young nephew Louis XVII died in prison in June 1795, the Count of Provence claimed the throne as Louis XVIII.

Charles X (Charles Philippe; 9 October 1757 – 6 November 1836) was King of France from 16 September 1824 until 2 August 1830. An uncle of the uncrowned Louis XVII and younger brother of reigning kings Louis XVI and Louis XVIII, he supported the latter in exile. After the Bourbon Restoration in 1814, Charles (as heir-presumptive) became the leader of the ultra-royalists, a radical monarchist faction within the French court that affirmed absolute monarchy by divine right and opposed the constitutional monarchy concessions towards liberals and the guarantees of civil liberties granted by the Charter of 1814. Charles gained influence within the French court after the assassination of his son Charles Ferdinand, Duke of Berry, in 1820 and succeeded his brother Louis XVIII in 1824.

At his coronation in 1825 he tried to revive the practice of the royal touch. The governments appointed under his reign reimbursed former landowners for the abolition of feudalism at the expense of bondholders, increased the power of the Catholic Church, and reimposed capital punishment for sacrilege, leading to conflict with the liberal-majority Chamber of Deputies.

The Flight to Varennes (French: Fuite de Varennes) during the night of 20–21 June 1791 was a significant event in the French Revolution in which the French royal family—comprising Louis XVI, Marie Antoinette, the Dauphin Louis Charles, Marie-Thérèse, Madame Royale, and Madame Élisabeth—unsuccessfully attempted to leave Paris for Montmédy, along with loyal members of their retinue. The King hoped to regain his freedom there, with the protection of royalist troops, as the Revolution was intensifying and the threat to the royal family's safety grew. They reached the small town of Varennes-en-Argonne, where they were stopped and arrested after being recognised at their earlier stop in Sainte-Menehould.

This incident was a turning point after which Parisian hostility towards the monarchy, as well as towards the King and Queen as individuals, became much more pronounced. The King's attempted flight provoked charges of treason that ultimately led to his execution in 1793. The flight failed due to a series of misadventures, delays, misinterpretations, and poor judgements. The King's decisions and indecision on a number of matters, including the means and timing of the journey, allowed seemingly small matters to escalate.
