Which king of France was executed during the French Revolution?

The king of France who was executed during the French Revolution was Louis XVI. His reign saw increasing discontent among the populace due to financial difficulties, food scarcity, and the influence of Enlightenment ideas that challenged the traditional authority of the monarchy. The revolution began in 1789, and as it progressed, the monarchy was abolished. Louis XVI was arrested and put on trial for treason, ultimately being found guilty and sentenced to death. He was executed via guillotine on January 21, 1793. This event was pivotal in the course of the Revolution, symbolizing the end of absolute monarchy in France and the rise of republicanism.

Louis XIV was a prominent absolute monarch known for his lengthy reign and the centralization of state power during the 17th century, well before the Revolution. Louis XVIII, who came to the throne after the fall of Napoleon, ruled during the Bourbon Restoration in the early 19th century. Louis III is not recognized as a historical king of France; there is no king by that name associated with the relevant period or events related to the French Revolution.
