When Margaret was six (close enough), King Edward VIII abdicated the throne to marry American socialite Wallis Simpson. That bumped Margaret up to the little sister of the future queen, so saying "events of tremendous importance" may have been a little bit of an understatement.
So, how did we go from Princess Margaret to our 12 star signs? Thanks to the success of Margaret’s horoscope, Naylor earned himself a regular column in the newspaper, but was struggling to answer the reported 28,000 daily letters he’d receive. Craig Brown, Princess Margaret's biographer, wrote about Naylor's revolutionary methods in Ninety-Nine Glimpses of Princess Margaret: "He divided 360-degree transit into 12 zones, each of them spanning 30 degrees. He then named each of the 12 zones after a different celestial constellation, and offered blocks of predictions for each birth sign."
Although it is definitely worth adding that horoscopes do date back to Ancient Greece and Babylonia, Naylor’s simplification and the access he gave readers at the time, was revolutionary. The next time you’re trying to understand if you and the cute boy you just met are the perfect astrological match, you can give a little nod (and thank you) to Margaret.
