West Ham United Football Club are based in Upton Park, Newham, East London and have played their home matches at the 35,647 capacity Boleyn Ground stadium since 1904.

The clubs formative roots stretch back to their formation as a professional side in 1900, but existed for at least five years prior to this under the name Thames Ironworks F.C. who themselves were built upon the remains of Old Castle Swifts F.C. (a club formed in 1892).

They initially competed in the London League (Winners 1897-98) later joining the Southern League (Division 2 Champions 1898-99) and Western League (Western League Champions in 1907-08) before joining the full Football League in 1919. They enjoyed their first top flight season in 1923 and have never fallen outside the top two divisions. They have won the FA Cup three times: in 1964, 1975 and 1980 (runners up 1923, 2006), and also captured the now defunct Cup Winners Cup in 1965 (runners up 10 years later) and the Intertoto Cup in 1999. They also won the first War Cup in 1940. Their best finish in the top flight was a third place finish in 1986. They have been runners up twice in the Football League Cup (1966 and 1981) and shared the 1964 Charity Shield
