Originally named the Thames Ironworks & Shipbuilding football team (hence its nickname, the Hammers), the club reformed as West Ham United in 1900.
In 2016 they relocated from the Boleyn Ground - commonly known as Upton Park - to the London (Olympic) Stadium. Home matches in East London are often a sea of claret and sky blue jerseys, the club's official colours.
West Ham’s passionate fans are renowned for singing their famous team anthem, "I'm Forever Blowing Bubbles". Their honours include three FA Cup wins.
