The longtime activist, 39, was recognized for her fight against sexual violence in war zones.
"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 in a statement. "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."
Jolie just co-hosted a four-day global summit in London about the issue with British Foreign Secretary William Hague.
