The club was founded in 1961 after the ownership group withdrew membership to the American Football League and agreed to join the NFL as an expansion team. The team played home games at Metropolitan Stadium through the 1981 NFL season and have played their home games at Hubert H. Humphrey Metrodome (the home of the American League baseball team Minnesota Twins) since 1982. However, the future of the Metrodome is in doubt, as the Vikings (significantly encumbered by lease conditions at the stadium) are attempting to secure a new stadium for their own use.
