When Wallis Simpson and Edward, Prince of Wales, fell in love, the course of the monarchy was altered irrevocably. The British establishment couldn’t sanction the heir to the throne marrying a divorced American; one official called her a woman of “limitless ambition.”
And so in 1936, Edward abdicated the throne he had just inherited for the woman he loved. TIME named Simpson its first Woman of the Year, for becoming “the most-talked-about, written-about, headlined and interest-compelling person in the world.” This year, as another American struggled to navigate the royal family with her husband, Simpson reminds us that when modernity clashes with tradition, nobody emerges unscathed. —Suyin Haynes
