The “International Day of United Nations Peacekeepers”, May 29, is “a day to pay tribute to all the men and women who have served and continue to serve in United Nations peacekeeping operations for their high level of professionalism, dedication, and courage and to honor the memory of those who have lost their lives in the cause of peace.”
It was so designated by United Nations General Assembly Resolution 57/129, on December 11, 2002, after an official request of the Ukrainian Peacekeepers Association and the Government of Ukraine to the UN General Assembly and first celebrated in 2003. The date, May 29, marks the anniversary of the creation of the United Nations Truce Supervision Organization (UNTSO) in 1948 to monitor the ceasefire after the 1948 Arab-Israeli War, which was the first ever UN peacekeeping mission
