South Sudan was part of Sudan until 2011, when it gained independence after a referendum. Sudan has competed at the Olympics since 1960. Under IOC rules, the South Sudan NOC was not eligible for IOC membership until national sports federations had joined both the NOC and the corresponding international federation of five Olympic sports. Guor Marial competed as an Independent Olympic Athlete at the 2012 Summer Olympics, finishing 47th in the men's marathon. Margret Rumat Rumat Hassan competed as an Independent Olympic Athlete at the 2014 Summer Youth Olympics. By 2015, Sudanese federations were recognised in athletics, basketball, association football, handball, judo, table tennis and taekwondo. The South Sudan NOC was founded by representatives of these sports on 8 June 2015. After a recommendation by its executive board, the IOC admitted the NOC at its session in Kuala Lumpur by acclamation.
