Her Royal Highness Princess Margaret, Countess of Snowdon. Observers often characterised Margaret as a spoiled snob capable of cutting remarks and hauteur. She was said to look down on her grandmother, Mary of Teck, because Mary was born a princess with the "Serene Highness" style, whereas Margaret was born a royal princess with the "Royal Highness" style. Their letters, however, provide no indication of friction between them.
Margaret could also be charming and informal. People who came into contact with her could be perplexed by her swings between frivolity and formality. Former governess Marion Crawford wrote in her memoir, "Impulsive and bright remarks she made became headlines and, taken out of their context, began to produce in the public eye an oddly distorted personality that bore little resemblance to the Margaret we knew."
Margaret's acquaintance Gore Vidal, the noted American writer, wrote, "She was far too intelligent for her station in life." He recalled a conversation with Margaret in which, discussing her public notoriety, she said, "It was inevitable, when there are two sisters and one is the Queen, who must be the source of honour and all that is good, while the other must be the focus of the most creative malice, the evil sister. Princess Margaret's private life was for many years the subject of intense speculation by media and royal-watchers. Her house on Mustique, designed by her husband's uncle Oliver Messel, a stage designer, was her favourite holiday destination. Allegations of wild parties and drug taking were made in a documentary broadcast after the Princess's death.
Biographer Warwick suggests that Margaret's most enduring legacy is an accidental one. Perhaps unwittingly, Margaret paved the way for public acceptance of royal divorce. Her life, if not her actions, made the decisions and choices of her sister's children, three of whom divorced, easier than they otherwise would have been.
