Query: What organization was founded in July of 2002?
Context: In June 1999, Gaddafi visited Mandela in South Africa, and the following month attended the OAU summit in Algiers, calling for greater political and economic integration across the continent and advocating the foundation of a United States of Africa. He became one of the founders of the African Union (AU), initiated in July 2002 to replace the OAU; at the opening ceremonies, he proclaimed that African states should reject conditional aid from the developed world, a direct contrast to the message of South African President Thabo Mbeki. At the third AU summit, held in Libya in July 2005, he called for a greater level of integration, advocating a single AU passport, a common defence system and a single currency, utilising the slogan: "The United States of Africa is the hope."
