Hillary Clinton called on female leaders to "step up and speak out" in a video (below) for the public that asks American women to "be bold."
Made during the 2017 MAKERS conference, the video includes footage of Clinton speaking about January's Women's Marches and breaking through gender-based barriers.
"Despite all the challenges we face, I remain convinced that, yes, the future is female," she said, the Daily Mail reports.
Her words mark the first video statement made to the public since President Donald Trump took the oath of office last month.
She said: "Just look at the amazing energy we saw last month as women organized a march that galvanized millions of people all over our country and across the world.
"Now more than ever we need to stay focused on this year's conference: Be bold. We need strong women to step up and speak out. We need you to dare greatly and lead boldly.
"So please, set an example for every woman and girl out there who's worried about what the future holds and wonders whether our rights, opportunities and values will endure.
"And remember, you are the heroes and history makers, the glass ceiling breakers of the future. As I've said before, I'll say again, never doubt that you are valuable and powerful and deserving of every chance and opportunity in the world."
MAKERS is an organization that allows women to share their stories. Their annual conference is themed "Be Bold" and is being held the second week of February at the Terranea Resort in Rancho Palos Verdes, California.
Justice Ruth Bader Ginsburg, Carli Lloyd, Gloria Steinem, Lilly Singh and Oprah Winfrey are among the star female leaders who have spoken through the organization's website.
The former first lady spoke of the pro-woman marches held in Washington D.C. and other cities around the globe.
"We watched women and men across this country and the globe stand up, speak out, and peacefully march for those values with one voice," Clinton said, People reports.
"It was awe-inspiring. We have to keep up the momentum. I will never stop believing in this country and our collective future. We are still, and will always be, stronger together."
