In early 1991, Bret Hart and Jim Neidhart (The Hart Foundation) were WWF Tag Team Champions. The Nasty Boys (Brian Knobbs and Jerry Sags) won a battle royal to face The Hart Foundation at WrestleMania VII. Due to Jimmy Hart's interference, The Nasties defeated The Harts for the championship

In 1995, Jerry Lawler convinced Hakushi that Bret Hart was a "racist", leading to a short-term rivalry between the two competitors. Hart faced Hakushi at the first ever In Your House PPV, defeating the Japanese star, although Hakushi came back later in the night and got revenge. 

No, not the guy who played Mankind - JR Foley was a manager in the Stampede territory that feuded with the Hart family for years, seconding such stars as The Stomper and Dynamite Kid in matches against Bret Hart.

While Eric Bischoff and Bret Hart may have had backstage differences during Hart's WCW run, their on-screen rivalry began at Starrcade '97 when The Hitman opposed Bischoff's nWo. A couple of years later, Hart participated in an angle on Nitro where he screamed "Hey, Bischoff - I quit!"

Late into Bret Hart's WWF run and in the midst of their red-hot Canada vs. USA angle, The Patriot debuted as a symbol of American pride. Bret Hart battled The Patriot at that year's Ground Zero pay-per-view and later teamed with brother-in-law Davey Boy Smith against the masked crusader and Vader in a flag match.

The Hart Foundation took on Demolition at two different SummerSlams. In 1988, The Harts fell short when Jimmy Hart aided Ax and Smash. Two years later, The Foundation battled Ax, Smash and Crush and were aided by The Legion of Doom - an assist that gave Bret and Jim the WWF Tag Team Titles.

Although Bret Hart and WWE Hall of Famer Jim Neidhart were partners in The Hart Foundation, there was a period where they didn't see eye to eye. When Owen Hart became King of the Ring in 1994, it was because Neidhart was helping him in his feud with Bret. The ex-partners wrestled on house shows as well.

One of Bret Hart's earliest rivalries after winning his first Intercontinental Title was against The Warlord. While Warlord never captured the gold, the two battled for several months on the house show circuit in both singles and tag team matches.

One of Bret Hart's favorite all-time big men to work with was Bam Bam Bigelow, because the two could have a believable, fast paced match. Such was the case in the finals of the first King of the Ring tournament, where Hart pinned Bam Bam. They also battled it out during a WWF tour of Japan and on Monday Night Raw.

Prior to capturing their first set of WWF World Tag Team Titles, Bret Hart and Jim Neidhart were constantly at odds with The Killer Bees (B. Brian Blair and Jumpin' Jim Brunzell). They fought numerous times on the house show circuit in 1986, including a bout on Saturday Night's Main Event.

Bret Hart respected Chris Benoit's wrestling ability so much that he'd arranged for hin to get a WWF tryout in the mid-1990s. Years later, the two engaged in a tribute match on WCW Nitro to Bret's fallen brother Owen Hart. That same year, the two battled for the vacant WCW World Title at Mayhem.

A few months after capturing his first WWF World Title, Bret Hart faced WWE Hall of Famer Yokozuna in the main event of WrestleMania IX. Yokozuna won the contest under suspicious circumstances, and Hart went through a full year of redemption before facing Yoko at WrestleMania X - and dethroning him.

The rivalry between Bret Hart and WWE Hall of Famer Jerry Lawler began in 1993 and lasted several years. It began with The King attacking The Hitman after he was named the first King of the Ring. From there, they competed at SummerSlam, on Monday Night Raw and even several times in Lawler's USWA.

During the early 1980s, few were matched as perfectly as Bret Hart and The Dynamite Kid. Together, they had classic and vicious  matches in Stampede (including one of the first Ladder Matches). When they both became members of a tag team in the mid-1980's WWF, they turned it up a notch again.

Bret Hart was a part of The Undertaker's very first WWF match (Survivor Series 1990) and battled The Dead Man on house shows. Most famously, the two battled for the WWF World Title at SummerSlam 1997, with guest referee Shawn Michaels accidentally giving Hart the win in that match.

Some of Bret Hart's greatest matches were at the hands of WWE Hall of Famer Mr. Perfect.

They also crossed paths at the following year's King of the Ring, and even for several bouts in WCW.

When Bret Hart teamed up with some of his brothers at the 1993 Survivor Series, he didn't expect his youngest brother Owen Hart to start rebelling against him. What followed led to a near-two-year feud, including interactions at WrestleMania X, SummerSlam, Survivor Series and Monday Night Raw before they finally reconciled.

During the early 1980s, Canadian wrestling standout Leo Burke teamed with both Bret and Keith Hart with some success. Soon after, however, he began a rivalry with The Hitman over the Stampede North American Title that included the two wrestlers trading the championship at least five times between them.

Five-time WCW World Champion and WWE Hall of Famer Booker T may not have been where he is today without the help of Bret Hart.

Bret Hart and The 123 Kid (a/k/a WWE Hall of Famer Sean Waltman) only had one match, but it was a doozy. Both fan favorites, The Hitman defended his WWF World Title against The Kid on an episode of Monday Night Raw in 1994. Hart won the match by submission.

At the In Your House: Final Four PPV, there were four men vying for the WWF World Title: Bret Hart, Sid, The Undertaker and Vader.

While WWE Hall of Famer Jimmy Hart was the manager of Bret Hart (and they share a surname despite not being related), The Hitman and Jim Neidhart fired The Mouth Of The South in 1988. From that point forward, Jimmy kept 1/4 of The Hart Foundation's pay, giving it away to The Rougeau Brothers.

The first Tiger Mask (Satoru Sayama) is generally regarded as one of the world's best light heavyweights, having classic matches with the likes of Dynamite Kid, Black Tiger and others.

In the summer of 1992, Bret Hart was one of the first wrestlers to stand up to Papa Shango (a/k/a WWE Hall of Famer The Godfather). Shortly after the rivalry began, Hart won his first WWF World Championship, and defended the gold against Shango on Saturday Night's Main Event.

Bret Hart once referred to The Stomper as the greatest Canadian wrestler of all time. While we'd likely choose The Hitman (and others) over The Stomper, he and Hart had a fantastic rivalry in Stampede Wrestling circa 1983, with the two trading wins. 

Bret Hart and WWE Hall of Famer Randy Savage battled only a handful of times, but always in memorable matches. The first time the WWE Hall of Famers met was on a episode of Saturday Night's Main Event; one of Hart's first "great" WWF matches ever. They later faced off in Japan in a match for Hart's World Title.

In 1999, Bret Hart called out WWE Hall of Famer Bill Goldberg on Nitro to challenge him to a fight.

In the early 1980s, Bret Hart feuded extensively with Bad News Allen in the Stampede territory. Years later in the WWF, Hart and Bad News (now Bad News Brown) began feuding in 1988, when Bad News refused to split the WrestleMania IV battle royal prize money and instead attacked The Hitman.

Another rivalry that had roots in Stampede, Bret Hart and Davey Boy Smith began in that territory together and then feuded as The Hart Foundation and British Bulldogs. Later, brothers-in-law Hart and Smith had a classic match at SummerSlam '92 and several high-profile matches for Hart's WWF World Title.

Sure, we know what Bret Hart and Vince McMahon thought of each other backstage, but what about on screen? Hart first became at odds with Vince McMahon as The Hitman slowly began turning heel. Following the Montreal Screwjob, Hart returned to WWE in 2010 and wrestled McMahon at WrestleMania.

A rivalry between Bret Hart and WWE Hall of Famer Stone Cold Steve Austin that began as a one-off match in 1996 turned into one of the WWF's top feuds and the catalyst for both Hart and Austin to switch allegiances. Their matches involved The Hart Foundation and centered around a Submission Match at WrestleMania XIII.

Beyond their infamous match at the Survivor Series in 1997, the rivalry between Bret Hart and WWE Hall of Famer Shawn Michaels runs beyond that.
