The Hart Foundation
After participating at the Royal Rumble in January 1990, The Hart Foundation defeated The Bolsheviks in 19 seconds at WrestleMania VI and began feuding with Demolition, who had just won the WWF Tag Team Championship against The Colossal Connection at WrestleMania VI. At SummerSlam in 1990, The Hart Foundation began their second, and final, WWF Tag Team Championship reign by defeating Demolition members Crush and Smash in a two out of three falls match with some help from Legion of Doom. On October 30, the Hart Foundation lost the title to The Rockers (Marty Jannetty and Shawn Michaels), but a few days later, President Jack Tunney reversed the decision and the win was never acknowledged on television. The Hart Foundation's reign lasted until WrestleMania VII, where they lost to The Nasty Boys, after which the team split.
