Here's what ELLE learnt at the days' events.
1) That the aim of the summit is to change attitudes towards rape which suggest it is a lesser crime or inevitable in war and to unite governments and leaders to condemn sexual violence as a weapon of war.
2) That since the war broke out in Syria, approximately nine million Syrians have been driven from their homes and nearly three million refugees are in neighbouring countries, all bearing stories of murder, starvation and rape.
3) The reason behind In the Land of Blood and Honey, a film directed and produced by Angelina Jolie, which she hopes will make people more understanding and more thoughtful towards Bosnia-Herzegovina, which needs more support today than it is getting from the international community, she stated at the summit on Wednesday.
4) That 117 countries were formally represented at the summit, with over 2,000 delegates from around the world and over 140 free events held for the public over the four days.
5) That Angelina Jolie wrote an unsigned note at the event, which stated: All voices are valuable. Everyone. And all women and girls must be heard.
