"In 1518 in Strasbourg, a woman started dancing for no reason. Over the course of a month, 400 other people joined her. Soon close to 50 people would dance themselves to death in what became known as the Dancing Plague of 1518. Realistically, people were probably caught up in a case of mass hysteria. Another theory is that the grain they grew locally was poisoned by ergot fungi. Whatever caused it, I can’t imagine the feeling knowing a family member died because they danced until their heart exploded."
All this was loooong before 'we' became a kingdom in it's current form
