However, Margaret's mother told a friend that she "regretted" that her daughters did not go to school like other children, and the employment of a governess rather than sending the girls to school may have been done only at the insistence of King George V. J. M. Barrie, author of Peter Pan, read stories to the sisters as children. Margaret's grandfather, George V, died when she was five, and her uncle acceded to the throne as King Edward VIII. Less than a year later, on 11 December 1936, in the abdication crisis, he left the throne to marry Wallis Simpson, a twice-divorced American, whom neither the Church of England nor the Dominion governments would accept as queen. The Church did not recognise the marriage of a divorced woman with a living ex-husband as valid. Edward's abdication made a reluctant Duke of York the new king, and Margaret became second in line to the throne, with the title The Princess Margaret to indicate her status as a child of the sovereign.

They spent Christmas at Sandringham House before moving to Windsor Castle, just outside London, for much of the remainder of the war. Viscount Hailsham wrote to Prime Minister Winston Churchill to advise the evacuation of the princesses to the greater safety of Canada, to which their mother famously replied, "The children won't go without me. I won't leave without the King. And the King will never leave." At Windsor, the princesses staged pantomimes at Christmas in aid of the Queen's Wool Fund, which bought yarn to knit into military garments. In 1940, Margaret sat next to Elizabeth during their radio broadcast for the BBC's Children's Hour, addressing other children who had been evacuated from cities. Margaret spoke at the end by wishing all the children goodnight. Unlike other members of the royal family, Margaret was not expected to undertake any
