Louis XVI, also called (until 1774) Louis-Auguste, duc de Berry, (born August 23, 1754, Versailles, France—died January 21, 1793, Paris), the last king of France (1774–92) in the line of Bourbon monarchs preceding the French Revolution of 1789.

Firstly, it is important to understand that the French Revolution was a period of significant social and political upheaval in France that lasted from 1789 until 1799. It marked the end of the monarchy in France and the rise of a new republican government.
The King of France at the time of the French Revolution was **King Louis XVI**. He ascended to the throne in 1774 and was the reigning monarch when the revolution began in 1789. Louis XVI was not well-equipped to deal with the challenges facing France at the time, including economic crisis, social inequality, and growing discontent among the populace.
However, Louis XVI's reign was marked by his resistance to reform and his inability to effectively address the grievances of the French people. This ultimately led to his downfall during the revolution. In 1792, the monarchy was abolished, and Louis XVI was arrested, tried for treason, and executed by guillotine in January 1793.
Overall, King Louis XVI's reign during the French Revolution was marked by his inability to adapt to the changing political landscape and his resistance to reform, which ultimately played a significant role in his downfall and the end of the monarchy in France.
