Princess Margaret, Countess of Snowdon (Margaret Rose; 21 August 1930 – 9 February 2002), was the younger daughter of King George VI and Queen Elizabeth the Queen Mother, and the only sibling of Queen Elizabeth II. Born when her parents were the Duke and Duchess of York, she became second in line to the British throne after her father's accession in 1936, though her place in the succession declined as her sister's children and grandchildren were born.
Margaret spent much of her childhood with her family and elder sister. During the Second World War, the princess remained at Windsor Castle despite suggestions that she and Elizabeth should be evacuated to Canada. Too young to perform official duties, she continued her education while her sister undertook public responsibilities. Her father's death in 1952, which brought Elizabeth to the throne, marked a turning point in Margaret's life and coincided with her relationship with RAF officer Peter Townsend.
