One of the more memorable films I've ever seen and I believe it gives an accurate account of what true Monarchy is all about. I've always thought the best motto for Monarchy would be: "One for all and all for one!". This attitude is expressed well in the film The King. I think the battle scene between France and England is also an accurate depiction of how brutal and unforgiving the battles between ancient peoples used to be. Perhaps the only other depiction of such battles that is on par with the battle scene in The King is the "Battle of the Bastards" battle depicted in the series The Game of Thrones? Great ancient kings used to ride into battle with their armies and fight along side their men. True leaders always lead from the front, thus gaining the respect of their fellow countrymen. Ultimately, this is most likely why the wars of monarchs under a monarchy are often less bloody than the wars of the people under a democracy, because kings fight in all the wars they start, whereas under democracy the people who support war in far of lands get to stay home and go about their daily lives without much interruption, never paying too much mind to those dying in those far off lands....
Could anyone who reads this imagine Trump, Biden, Obama, Bush, etc. leading anyone into battle? Of course not, these are Western business men who push pencils and paper from the safety of their seats. Furthermore, two of the presidents previously mentioned dodged military service altogether, Trump being on of them. So the question becomes, why and when did humans decide it was better for cowardly businessmen and pencil pushers to lead nations into war than a King who will go to war with you in person? Answer: research the French Revolution.
