For years, many countries and regions have been holding their own Refugee Days and even Weeks. One of the most widespread is Africa Refugee Day, which is celebrated on 20 June in several countries.
As an expression of solidarity with Africa, which hosts the most refugees, and which traditionally has shown them great generosity, the UN General Assembly adopted Resolution 55/76 on 4 December 2000. In this resolution, the General Assembly noted that 2001 marked the 50th anniversary of the 1951 Convention relating to the Status of Refugees, and that the Organization of African Unity (OAU) had agreed to have International Refugee Day coincide with Africa Refugee Day on 20 June. The Assembly therefore decided that, from 2001, 20 June would be celebrated as World Refugee Day.
[Note: The OAU was replaced by the African Union on 9 July 2002.]
