The International Day of United Nations Peacekeepers is held annually on May 29. It is an opportunity to appreciate the invaluable contribution of the uniformed and civilian personnel who work for the organization.

• The day honors over 4,000 peacekeepers who have lost their lives while serving under the U.N. flag since its inception in 1948.
• Officially established by the General Assembly of the U.N., the day marks the date when the first U.N. peacekeeping mission was named the United Nations Truce Supervision Organization (U.N.T.S.O.) in 1948.
• It coincided with the year U.N.T.S.O. began operations in Palestine.
