Sport has been used to help divided communities in Northern Ireland overcome historical tensions. The "Troubles" from the 20th century led to deep divisions along religious lines. Since the 1998 Good Friday Agreement, sports organizations have implemented cross-community programs to reduce mistrust between Catholic and Protestant communities. Programs like those from the Irish Football Association, Gaelic Athletic Association, and Football4Peace have emphasized shared interests in health and fun over religious differences through integrated sports clubs and schools. These efforts have helped communities in Northern Ireland start to overcome segregation and build cross-community relationships.
