Jolie has fronted a campaign against sexual violence in military conflict zones by the UK government, which made the issue a priority of its 2013 G8 presidency. In May 2012, she launched the Preventing Sexual Violence Initiative (PSVI) with Foreign Secretary William Hague, who was inspired to campaign on the issue by her Bosnian war drama "In the Land of Blood and Honey" (2011). PSVI was established to complement wider UK government work by raising awareness and promoting international co-operation. Jolie spoke on the subject at the G8 foreign ministers meeting, where the attending nations adopted a historic declaration, and before the UN security council, which responded by adopting its broadest resolution on the issue to date. In June 2014, she co-chaired the four-day Global Summit to End Sexual Violence in Conflict, the largest-ever meeting on the subject, which resulted in a protocol endorsed by 151 nations.
