The military regime governed Haiti until 1994, and according to some sources included drug trafficking led by Chief of National Police Michel François. Various initiatives to end the political crisis through the peaceful restoration of the constitutionally elected government failed. In July 1994, as repression mounted in Haiti and a civilian human rights monitoring mission was expelled from the country, the United Nations Security Council adopted United Nations Security Council Resolution 940, which authorized member states to use all necessary means to facilitate the departure of Haiti's military leadership and to restore Haiti's constitutionally elected government to power.
