Born Margaret Rose in 1930 at Glamis Castle in Scotland, Princess Margaret, Countess of Snowdon was the younger daughter of King George VI and Queen Elizabeth The Queen Mother and the only sibling of Queen Elizabeth II.
After the war, Margaret fell in love with Group Captain Peter Townsend. In 1952, Margaret's father died, her sister became Queen, and Townsend divorced his first wife. Early the following year, he proposed to Margaret. Many in the government believed he would be an unsuitable husband for the Queen's 22-year-old sister, and the Church of England refused to countenance marriage to a divorced man.
Margaret eventually abandoned her plans with him and in 1960, she accepted the proposal of the photographer Antony Armstrong-Jones, who was created Earl of Snowdon by the Queen. The couple had two children. They divorced in 1978.
Margaret was often viewed as a controversial member of the British royal family. Her divorce earned her negative publicity, and she was romantically associated with several men. Her health gradually deteriorated in the final two decades of her life.
A heavy smoker for most of her adult life, she had a lung operation in 1985, a bout of pneumonia in 1993, and at least three strokes between 1998 and 2001. She died at King Edward VII's Hospital in 2002.
