The Birth of Westham

The principal element of the badge is the crossed pair of rivet hammers, tools that were used in the shipbuilding industry. The Blackwall and Canning Town neighbourhoods surrounding the Thames Ironworks echoed to the sound of hammers; steam hammers, sledge hammers and rivet hammers.

Seven large mechanical steam hammers would punch small holes near the edges of the iron plates which would be joined to build the ships. The plates would be put in place and fixed together with rivets by teams of five, three inside the emerging vessel and two outside.

Inside the ship one member of the team would heat the rivets till they were white hot and, using Iron Fingers (blacksmith's tongs), throw them to a second person, known as a "catch-boy" or "putter-in", who would pick the rivet up and place it the hole, also using tongs. The third person was known as the "holder-on" and he would then smash the rivet home with a sixteen-pound sledgehammer and then use his sledgehammer to hold the rivet in place while the men on the other side flattened the other end of the rivet.

Outside the ship, exposed to the elements, two men with rivet hammers – one right-handed, one left-handed – would hammer the protruding and still glowing rivet flat, so securing one of the many points necessary to link each of the ship's large plates.

The crossed hammers were also incorporated into the coat of arms of the County Borough of West Ham and those of its successor, the modern London Borough of Newham.[146] The Thames Ironworks lay partly within what is now the London Borough of Tower Hamlets. However, the blacksmith's tongs in that Borough's coat of arms represent the local saint, Dunstan, the patron saint of Stepney and metalworkers,[147] rather than the Ironworks.

A yellow or white tower was added, intermittently, from the 1950s onwards.[148] The primary reason for this seems to be to represent Anne Boleyn's Tower, the most notable feature of Green Street House, an originally Tudor group of buildings which stood next to the Boleyn Ground until demolished in 1955. Green Street House was also known as Boleyn Castle through an association with Anne Boleyn. The manor was reputedly one of the sites at which Henry VIII courted his second queen, though there is no documentary evidence to support the tradition.

A shield has been used in many iterations of the club badge, and the shape of the 2016 version matches the cross-section on the hull of HMS Warrior, the most famous ship built by the Thames Ironworks. However examining draughtsman's diagrams of the ship casts doubt on the resemblance between the shield and the ship.

The origins of West Ham's links with hooliganism starts in the 1960s with the establishment of The Mile End Mob (named after an area of the East End of London). 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 and Dagenham.

The Inter City Firm were one of the first "casuals", so called because they avoided police supervision by not wearing football-related clothing and travelled to away matches on regular 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.
