The actress-turned-director stepped behind the camera last year for In the Land of Blood and Honey, a story about a romance between a Serbian soldier and a Bosnian woman.
Her efforts were praised by government officials at the Assembly of Sarajevo Canton Parliament for drawing attention to the area, and they decided to award her with a special citizenship prize, reports contactmusic.com.
A ceremony was held last week, where a pre-recorded video message from Jolie was played.
In the clip, she said: "I am deeply grateful to the citizens of Sarajevo and the Sarajevo Canton assembly for bestowing upon me this incredible honour of citizenship. I am so proud to now be a part of such an extraordinary part of the world and fellow citizen to the people I deeply love and admire."
