The Hart Foundation referred to several teams or stables in
the World Wrestling Federation (WWF), usually consisted of
members or close friends of the Hart wrestling family from
Canada. The original Hart Foundation (1985–1991) consisted
of Jim "The Anvil" Neidhart and Bret "The
Hitman" Hart, who were initially managed by Jimmy Hart
and won the WWF Tag Team Championship twice. In 1991, after
the team was disbanded, Neidhart teamed briefly with Bret's
younger brother Owen Hart as The New Foundation. They also
teamed in 1994. In 1997, Bret, Neidhart and Owen joined
forces with another brother-in-law, The British Bulldog, and
Brian Pillman, to re-form the Hart Foundation as a
pro-Canada/anti-American alliance, which at the time held
all the available WWF championships: the WWF Championship,
Intercontinental Championship, European Championship, and
Tag Team Championship.
