Although their royal roles—and personalities—couldn't have been more different, Queen Elizabeth and Princess Margaret shared a close bond throughout their lives. The late Queen's only sibling, who died in 2002, has long been remembered as an outspoken, ultra-glam wild child. But after three of Queen Elizabeth's four children ended up divorced in the '90s, the sisters experienced a role reversal that no one expected.
In a classic case of heir and spare, Princess Margaret is said to have suffered from an inferiority complex when it came to Elizabeth. "As a young woman she had always felt that the Queen was so good and perfect while she was very much the opposite, doomed to an unhappy marriage and a succession of unsuitable romances," author Ingrid Seward wrote in her book My Mother and I (via the Daily Mail).
