The Hart wrestling family, sometimes known as the Hart dynasty, is a mainly Canadian family with a significant history within professional wrestling. The patriarch of the family was wrestling legend Stu Hart (1915–2003). An amateur and professional wrestling performer, promoter and trainer, Stu owned and operated his own wrestling promotion, Stampede Wrestling. He also trained some of the most well known stars in wrestling history including Superstar Billy Graham, Fritz Von Erich, Edge, Chris Jericho, Chris Benoit, Christian and his sons Bret Hart and Owen Hart. All of Stu's eight sons were wrestlers and two of them, Bret and Owen, achieved considerable fame and success in the World Wrestling Federation (WWF, now WWE), with many of the WWF's biggest storylines in the mid-1990s being built around Bret and Owen and their brothers-in-law. The family is closely associated with Canada in the North American wrestling landscape and its Canadian heritage has often been emphasized in wrestling storylines, even to the point of overt opposition to American culture, but most of its members also have U.S. citizenship through the family's American-born matriarch, Helen Hart.
