Bret Hart has won the most wrestling championships of anyone in the family. He won his first title belt in the World Wrestling Federation while teaming with brother-in-law Jim Neidhart (Ellie Hart's husband) to form The Hart Foundation tag team. They had a feud with the British Bulldogs (Diana Hart's husband Davey Boy Smith and Bret Hart's sister-in-law's husband Dynamite Kid, who were first cousins in real life). On January 26, 1987, Hart and Neidhart defeated the Bulldogs to win the WWF Tag Team Championship. After the Hart Foundation split up, Owen Hart began teaming with Neidhart as The New Foundation. Bret went on to have a successful career as a singles wrestler, holding the WWF World Heavyweight Championship five times.
