The main rivalry heading into Backlash pits Triple H against Randy Orton over the WWE Championship. The feud started in February when Orton attacked Triple H's wife, Stephanie McMahon. As a result, Triple H convinced Orton to challenge him at WrestleMania XXV, which Orton did, and Triple H accepted. At WrestleMania, Triple H defeated Orton to retain the championship. The following night on Raw, WWE chairman Vince McMahon announced that there will be a six-man tag team match at Backlash between Triple H, Shane McMahon and himself against the Legacy (Orton, Ted DiBiase and Cody Rhodes) which was later turned into a WWE Championship match by new General Manager of Raw, Vickie Guerrero. That same night, Shane and Triple H were attacked by the Legacy, but were saved by a returning Batista. Vince announced that Batista would be taking his place at Backlash.
Another rivalry heading into Backlash brings together John Cena and Edge over the World Heavyweight Championship.
