Louis XVI was the last king of France before the French Revolution. He ruled from 1774 until 1792, when he was deposed and later executed by guillotine in 1793. Louis XVI's reign was marked by economic difficulties, social unrest, and political turmoil, which ultimately led to the collapse of the monarchy. He was known for his indecisiveness and inability to effectively address the challenges facing France, and his reign is often associated with the decline of the absolute monarchy and the rise of revolutionary sentiment.
