Who was the last king of France executed for treason during the French Revolution?

Louis XVI was the last king of France executed for treason during the French Revolution, which was a significant event in world history. His execution on January 21, 1793, marked a pivotal moment in the Revolution, highlighting the shift from monarchy to the ideas of republicanism and citizenship. Louis XVI's reign was characterized by financial difficulties, social unrest, and an inability to address the needs of his subjects, leading to widespread discontent and ultimately the call for revolution.

The revolutionary government viewed him as a traitor to the nation because of his attempts to flee France and his perceived collusion with foreign monarchies to restore the old regime. His execution symbolized the end of absolute monarchy in France and served as a warning against tyranny. The subsequent phases of the Revolution involved greater radicalism and the establishment of a republic, demonstrating the profound impact of Louis XVI's trial and execution on French society and governance.
