Ludwig II was King of Bavaria from 1864 until his death in 1886 :: Ludwig II was known as the "Mad King of Bavaria" as during the King's frequent fits of madness, his Courtiers called upon an orchestra to play certain passages of 140 notes or less from Tchaikovsky's ballet Swan Lake... These notes were trusted to calm the King's irrational calls for war on random countries or for his army to march against his own subjects...
