Watch 11-Year-Old Meghan Markle Protest Sexist Soap Ad

Meghan Markle has a long and storied track record of advocating for women's rights.

But did you know she's been an activist since the age of 11? On the occasion of International Day of the Girl, the official Sussex Royal Instagram account posted an empowering message alongside a video that featured the Duchess as a child.

In the video, Markle penned a letter to the manufacturers of Ivory Dishwashing Liquid because they used the word "her" in a commercial.

The company ended up changing their ad, and Markle's pluck and tenacity landed her a spot on children's cable show "Nick News" in 1993.

Markle's advice for budding feminists and young women all over the world? "Visualize your highest self, and show up as her."

Preach!

Read the full statement from the Duke and Duchess:

Today is International #DayoftheGirl, a day observed globally and created by the United Nations to acknowledge the gender inequality that exists worldwide. Be it lack of access to education, stigma surrounding Menstrual Hygiene Management, forced child marriage, legal or medical inequality, or gender-based violence, there is a pressing need to support young women in their path to excellence.

It is also a day to celebrate and encourage girls to know their value and to support them in taking action to grow into the women they wish to be.

The Duchess of Sussex has been a long time advocate for women's and girls rights and at the age of eleven campaigned against a sexist advertisement, which was then changed. No matter what age, or what background you have the power to make an impact.

HRH recently shared a quote during a speech in Cape Town: “Visualize your highest self, and show up as her.”

To all of the young girls reading this today on International Day of the Girl, that quote is for you.
