Princess Margaret Almost Converted to Catholicism – Possibly True
In The Crown, we see both the grandiose events in Royal Family history, like Charles and Diana’s wedding, as well as smaller moments that give us an insight into what the personalities of these larger-than-life characters were really like. In one storyline, Princess Margaret is on a personal spiritual journey. Even though she was a member of the most pro-Catholic faction of the Church of England, she rejected her priest friend’s invitation to convert.

The book about Princess Margaret confirms that she was, in fact, considering conversion to Islam. Her loyalty to her sister prevented her from following through with it.
