Louis XIV the Sun-King born of royalty, considered by many including himself as given the divine right to rule by god.
Built himself one of the largest palace complexes in the world at Versailles (12 miles of roads, 200,000 trees, 50 fountains, 2,150 windows, 67 staircases, 6,000 paintings, 1,500 drawings, 2,100 sculptures and 5,000 pieces of furniture), went all catholic and revoked the Edict of Nantes, banning protestant teaching, burning their churches and annulling their marriages and in doing so lost many skilled artisans who sneaked out of the country to England, Germany and the Americas.
But he did strengthen the army, annul the power of his barons by having them serve at his court, get a wet humid part of America named for him, encourage piracy and become the power of Europe, eventually beggaring his country fighting the War of Spanish succession, he patronised the arts, encouraged industry, fostered trade and commerce, and sponsored the founding of an overseas empire, all in all he was considered a great king.
In taking over one of the preeminent methods of modern broadcasting he (Musk) may be going for the top job, recognising its ability to circumvent traditional media and give him unprecedented access and command of the thoughts of voters, and in doing so, become the new Sun-King, of America.
A better option than Trump, De Santis and the corpse king, maybe.
