Politics and sports or sports diplomacy describes the use of sport as a means to influence diplomatic, social, and political relations. Sports diplomacy may transcend cultural differences and bring people together. The use of sports and politics has had both positive and negative implications over history. Sports competitions or activities have had the intention to bring about change in certain cases. Nationalistic fervour is sometimes linked to victories or losses to some sport on sports fields. While the Olympics is often the biggest political example of using sports for diplomatic means, cricket and association football, as well as other sports in the global arena, have also been used in this regard. In the case of Apartheid, sport was used to isolate South Africa and bring about a major overhaul in the country's social structure. While ethnicity, race, social class and more can cause division, sports is also said to help blend differences.
