Jolie has gained international recognition for her work in helping refugees flee war-torn countries as an UNHCR Special Envoy. She also uses her celebrity platform to advocate for women's empowerment and safety all over the world, including working with the Preventing Sexual Violence Initiative (PSVI), which seeks to end the use of rape as a weapon in war.
"I try to speak for what I believe in," Jolie said of the causes she backs, which includes not only changing international laws that treat women like "second-class citizens," but enforcing those laws once changed.
"If you look across the world, there are far too many women and girls who are not only not seeing progress, their rights are slipping away from them," she said. "We also have to enforce [the laws after we change them]. So one of the things we are putting forward now is a proposal for a permanent international body to investigate war crimes, including mass rape and other sexual and gender-based violence."
In 2012, Jolie and former British foreign secretary William Hague founded the PSVI, and they've seen significant progress in terms of "awareness and discussion."
"Many more countries have made commitments," she said. "For example, 156 countries have pledged not to include amnesties for rape when they are negotiating peace agreements. It is hard to believe, but peace treaties routinely grant immunity to people who've carried out the most disgusting, violent crimes against civilians. So we have to make sure all those countries live up to that commitment."
In addition to being a champion for change, Jolie is also a single mother, raising children Maddox, 17, Pax, 15, Zahara, 14, Shiloh, 12, and twins Vivienne and Knox, 10; she split from their father, Brad Pitt, in 2015. Her next film, "Maleficent: Mistress of Evil," is set to hit theaters this October.
