Louis XVI's younger brother was Louis-Stanislas-Xavier, known as the Comte de Provence, who later became King Louis XVIII. He was more liberal than his brothers before 1789 but was no friend to reform initially. In June 1791, he left France and established a royalist center in Coblentz, conspiring against the revolutionary government and gathering émigré military forces. After Louis XVI was executed in 1793, Provence declared the dauphin Louis-Charles (Louis XVI's son) as King Louis XVII and assumed the role of regent. When the imprisoned Louis XVII died in 1795, Provence declared himself King Louis XVIII. He lived in exile in various countries and eventually accepted some revolutionary changes, leading to the Bourbon Restoration in 1814
. In summary, Louis XVI's brother fled France during the Revolution, led royalist efforts abroad, and ultimately became king in exile before the monarchy was restored.
