It's been 81 years since the last divorced American married into the royal family, and things have changed significantly since 1937 when Wallis Warfield Simpson of Baltimore, Maryland, married Prince Edward. Meghan Markle owes a debt of gratitude to Wallis Simpson who broke down barriers and forced a dialogue being the first divorced person to marry into the royal family, forcing an abdication and causing a rift within the family which was not healed in Prince Edward's lifetime.
While it was a different time, with different characters, and more on the line (Edward was to serve as king of England, while it is unlikely that Prince Harry will ever be called to do so, being sixth in line at this time), Prince Edward was forced to choose between "love and country" and chose the love of twice-divorced American Wallis Simpson.
But 81 years ago, Prince Harry would not have been allowed to marry Meghan Markle and remain even sixth in line to the throne, says News4Jax. Like Prince Edward and Wallis Simpson, Prince Harry would have likely been given a title like Duke of Windsor when marrying a divorced woman and forced to live in exile. It might not have gone that smoothly for Harry and Meghan as Markle's race would have been a big deal in 1937.
