Answer by taking a quote from the following article:

Dwayne Douglas Johnson was born on May 2, 1972 in Hayward, California, the son of Ata Johnson (nee Maivia) and professional wrestler Rocky Johnson (born Wayde Douglas Bowles). His maternal grandfather, "High Chief" Peter Maivia, was also a wrestler, and his maternal grandmother, Lia Maivia, was one of wrestling's few female promoters, taking over Polynesian Pacific Pro Wrestling after her husband's death in 1982, until 1988. Johnson's father is Canadian, of Black Nova Scotian, and a small amount of Irish, descent. His mother is of Samoan ancestry.

In April 2014, the Rock appeared in the opening segment of WrestleMania XXX along with Stone Cold Steve Austin and Hulk Hogan. On October 6 episode of Raw, the Rock made a surprise appearance to confront Rusev and Lana; this resulted in the Rock clearing Rusev from the ring.  The Rock appeared at the 2015 Royal Rumble event during the main event match, where he helped Roman Reigns fend off Big Show and Kane, and was booed ("for the first time in forever" (2003) as described by Dave Scherer of PWInsider.com) for doing so. The Rock endorsed Reigns' eventual victory, but the crowd still booed both him and Reigns. The Rock appeared at WrestleMania 31 alongside Ronda Rousey, getting into an in-ring altercation with Triple H and Stephanie McMahon (The Authority). Rock and Rousey prevailed after he attacked Triple H and she overpowered McMahon. On June 27, The Rock appeared at a live event in Boston where he confronted Bo Dallas, giving him a Rock Bottom in the process.  In January 2016, he returned to Raw in a segment which saw him diss Big Show, Lana and Rusev before getting into an altercation with WWE Tag Team Champions, The New Day. At WrestleMania 32, The Rock announced that WWE had broken the all-time WrestleMania attendance record before being interrupted by The Wyatt Family. The Rock defeated Wyatt Family member Erick Rowan in an impromptu match, giving him a Rock Bottom and pinning him in six seconds, which set the record for the fastest win in WrestleMania history. The Rock was then aided by the returning John Cena to fend off the remaining members of The Wyatt Family, Bray Wyatt and Braun Strowman.
