The 39-year-old accepted the honor before a private audience in recognition of her efforts to end sexual violence. Queen Elizabeth personally presented Jolie with the Insignia of an Honorary Dame Grand Cross of the Most Distinguished Order of St Michael and St George.
"The audience itself between Miss Jolie and the Queen was private," a Buckingham Palace spokesman said of the ceremony. "Her Majesty presented her with the insignia in its box. Mr. Pitt and the rest of the family were introduced to the Queen afterwards, however."
"To receive an honor related to foreign policy means a great deal to me, as it is what I wish to dedicate my working life to," Jolie said of her damehood. "Working on the Preventing Sexual Violence Initiative and with survivors of rape is an honor in itself. I know that succeeding in our goals will take a lifetime, and I am dedicated to it for all of mine."
Back in June, the actress gave a moving speech to kick off the Global Summit to End Sexual Violence in Conflict in London. "It is a myth that rape is an inevitable part of conflict,” she said. "There is nothing inevitable about it. It is a weapon of war aimed at civilians. It has nothing to do with sex, everything to do with power."
The United Nations Special Envoy also offered some ideas to ending sexual violence. "We need to see real commitment to go after the worst perpetrators, to fund proper protection for vulnerable people and to step in and help the worst affected countries. We need all armies, peacekeeping troops and police forces to have the prevention of sexual violence in conflict as part of their training."
The Oscar winner has been busy both directing and acting in her upcoming movie, By the Sea, with Pitt in Malta. The family is scheduled to return to Malta on Saturday.
Jolie is not the first dame in Hollywood. Julie Andrews, Judi Dench, Helen Mirren and Maggie Smith are also in the damehood.
It's been a big year for Jolie as she also became Mrs. Pitt over the summer. Check out her eccentric wedding dress, below:
