The Duchess of Sussex says her journey as a feminist began at the age of 11.
Speaking at a panel discussion to mark International Women's Day - alongside guests including musician Annie Lennox and model Adwoa Aboah - the Duchess said overnight that her curiosity was ignited after watching a "sexist" commercial in her childhood.
"I don't think I even really knew what sexism meant," she said. "I just knew that something struck me internally and was telling me that it was wrong but I knew that it was wrong."
The Duchess went on to say that putting her ideas down on paper helped crystalize her sense of right and wrong.
"It really set up the trajectory for me to say, 'If things are wrong and there is a lack of justice and there's an inequality, someone needs to say something. And why not me?'"
The royal also spoke about her hopes that her future child would be a feminist.
"I'd seen this documentary on Netflix about feminism and one of the things they said during pregnancy was, 'I feel the embryonic kicking of feminism,'" she smiled. "Boy or girl, whatever it is, we hope that's the case with our little bump."
The discussion was arranged by the Queen's Commonwealth Trust, on the day that the Duchess was named as the Trust's Vice President.
