If you’ve watched The Crown, you may get the idea that Princess Margaret was something of a black sheep in the royal family. There was much more to Margaret than that, however. She was, to the institution, the spare to the heir. To the rest of the world, she was part raw magnetism, part enigma, and completely fascinating.
The Countess of Snowdon was thought to live in Queen Elizabeth‘s shadow. In recent years, it’s become clear that it was Margaret who naturally had all the makings of a leader. Elizabeth had to work hard to propel herself to her rightful place. Margaret, for her part, often found herself lessening her shine as to not detract from her sister.
Many people don’t see Margaret beyond the scandals that marked her early life. She was the first royal in nearly a century to divorce. She lived unapologetically and was controversially critical of some of The Firm’s oldest traditions. Though Margaret wasn’t in the position to thrust the monarchy into modernity, she showed the world that not all royals are created equal.
