===Hooliganism===
The origins of West Ham's links with [[Football hooliganism|hooliganism]] starts in the 1960s with the establishment of The [[Mile End]] Mob (named after an area of the East End of London).<ref>{{Cite web |title=Want Some Aggro? |url=http://www.casspennant.com/book-aggro.shtml |archive-url=https://web.archive.org/web/20100314024542/http://www.casspennant.com/book-aggro.shtml |archive-date=14 March 2010 |access-date=5 October 2013 |publisher=casspennant.com }}</ref> During the 1970s and 1980s (the main era for organised football-related violence), West Ham gained further notoriety for the levels of hooliganism in their fan base and antagonistic behaviour towards both their own and rival fans, and the police. During the 1970s in particular, rival groups of West Ham fans from neighbouring areas often did battle with each other at games, most often groups from the neighbouring districts of [[Barking, London|Barking]] and [[Dagenham]].<ref name="CassPennant">{{Cite web |title=CONFESSIONS OF A TERRACE LEGEND The fights, the politics, the rival firms: Cass Pennant, notorious founder member of West Ham's InterCity Firm, recalls hooliganism's heyday. |url=http://www.casspennant.com/news.php?8 |archive-url=https://web.archive.org/web/20100314030123/http://www.casspennant.com/news.php?8 |archive-date=14 March 2010 |access-date=7 October 2013 |publisher=CassPennant}}</ref>

The [[Inter City Firm]] were one of the first "[[Casual (subculture)|casuals]]", so called because they avoided police supervision by not wearing football-related clothing and travelled to away matches on regular [[InterCity (British Rail)|InterCity]] trains, rather than on the cheap and more tightly policed "football special" charter trains. The group were an infamous West Ham-aligned gang. As the firm's moniker "inter city" suggests violent activities were not confined to local derbies – the hooligans were content to cause trouble at any game, though nearby teams often bore the brunt.<ref name="CassPennant" />
