Background
The International Day of Peace was established in 1981 by the United Nations General Assembly. Two decades later, in 2001, the General Assembly unanimously voted to designate the Day as a period of non-violence and cease-fire.
The United Nations invites all nations and people to honour a cessation of hostilities during the Day, and to otherwise commemorate the Day through education and public awareness on issues related to peace.
