You'll have to find it on Amazon Prime, but it's fascinating:
The term "Sun King" refers to King Louis XIV of France (1638–1715), who reigned from 1643 until his death in 1715. Louis XIV was given the nickname "Sun King" (in French, "le Roi Soleil") because he chose the sun as his personal emblem, symbolizing his absolute power and the idea that everything revolved around him, much like the planets revolve around the sun. He believed in the divine right of kings, meaning he saw himself as appointed by God to rule with ultimate authority.
Louis XIV is known for his long and powerful reign, during which he centralized the French government, built the extravagant Palace of Versailles, and established France as a dominant European power. His reign is often associated with the height of French cultural and artistic influence, as well as significant military expansion. However, his policies also led to heavy taxation and set the stage for financial troubles that contributed to the French Revolution later in the 18th century.
