The document discusses how socio-cultural factors influenced the development of sports in Britain. Prior to public schools, games were unorganized mob games with few rules. Public schools developed organized team sports with standardized rules and an emphasis on discipline, leadership, and fair play. Sports such as football, rugby, and cricket emerged from these schools and spread among the upper and middle classes through universities and social networks. The codification of sports rules and the growth of governing bodies further professionalized sports in Britain.
