Princess Margaret

Princess Margaret Rose Windsor (1930–2002), Countess of Snowdon and the younger sister of Queen Elizabeth II, was arguably one of the most popular royals in modern history. Known for her rebellious nature and determined personality, she made headlines around the world for her 'party-girl' lifestyle. Princess Margaret is also a fan-favourite on the Netflix TV series The Crown, where she is played in seasons one and two by Vanessa Kirby, and in the third and fourth seasons by Helena Bonham Carter.
