What significant action did Louis XVI take during the early stages of the French Revolution?

During the early stages of the French Revolution, Louis XVI took the significant action of attempting to escape from France, which ultimately led to his imprisonment. In June 1791, he and his family attempted to flee Paris to seek safety in the eastern provinces of the country, where they hoped to rally loyalist support. However, their escape failed when they were recognized in Varennes and subsequently arrested. This event demonstrated the waning support for the king and significantly undermined the monarchy's authority, as it exposed Louis's lack of confidence in his ability to govern and the growing discontent among the populace. The flight to Varennes fueled revolutionary fervor and directly contributed to the escalating tensions between the monarchy and revolutionary factions. This drastic act highlighted the precarious situation of the monarchy during the revolution and underscored Louis XVI's precarious grip on power in a rapidly changing political landscape.
