How are the actions of the Greasers and Socs influenced by the "Football Hooligans," concept as described in the text?

The author uses mainly English (newspaper) data about football violence (in and outside England) as an empirical base to explore how hooliganism can be theorised and understood. These data can usefully serve as a rough indication of the worldwide incidence of football hooliganism in the twentieth century. The author favours the figurational/process-sociological approach to football hooliganism which is historical and developmental. It also involves an exploration of the meanings of hooligan behaviour via an analysis of verbatim statements by the hooligans themselves, locates the football hooligans in the overall social structure, especially the class system, and examines the dynamics of the relationship between them and groups in the wider society. It is important, nevertheless, to stress that it is unlikely that the phenomenon of football hooliganism will be found always and everywhere to stem from identical social roots.
