1. Executive power: Louis XVI was the head of state and held executive authority. He had the power to appoint and dismiss ministers, make treaties, declare war and peace, and issue laws and regulations.
2. Legislative power: Although France had a parliament known as the Estates-General, the king ultimately held legislative authority. He could convene and dissolve the Estates-General at his will and had the power to veto any laws passed by the parliament.
3. Judicial power: The king was the highest judicial authority in the kingdom and had the power to administer justice. He could issue pardons, commute sentences, and oversee the judicial system.
4. Religious authority: As the eldest son of the French king, Louis XVI was also the head of the French Catholic Church. He held the title "Most Christian King" and had the power to appoint bishops and archbishops.
5. Military authority: Louis XVI was the commander-in-chief of the French military and had the power to declare war, raise armies, and negotiate peace treaties.
6. Diplomatic immunity: As a sovereign, Louis XVI enjoyed diplomatic immunity and could not be prosecuted or held accountable for his actions in foreign courts.
7. Divine right: Louis XVI believed in the divine right of kings, which meant that he believed his power came directly from God and that he was not accountable to any earthly authority.
However, it's important to note that Louis XVI's powers were not absolute and were limited by various factors, such as the influence of the aristocracy, the growing power of the bourgeoisie, and the evolving political and social ideas of the Enlightenment period.
