In January 2018 Ronda Rousey started his professional wrestling career, signing a contract with World Wrestling Entertainment (WWE), the most important federation in the world. She made his WWE debut the following April 8 at WrestleMania 34, defeating Stephanie McMahon and Triple H paired with Kurt Angle.
On August 19, at SummerSlam, 'Rowdy' won the Raw Women's Championship for the first time in her career and her reign, which lasted 231 days (from August 19 2018 to April 7 2019), is the second longest in the history of the title.
Rousey had her first WWE loss when she lost her title in the first-ever women's WrestleMania main-event to Becky Lynch in a triple threat match at WrestleMania 35. Rousey is the only woman to win a championship in both the UFC and WWE, as well as the only woman to headline a pay-per-view event in both companies.
Rousey was voted the best female athlete of all-time in a 2015 ESPN fan poll, and Fox Sports described her as "one of the defining athletes of the 21st century." In a video to her YouTube page, Ronda discussed a potential WWE return: “I don’t know when I’m going to go back.
I know I definitely do want to. But I don’t think I’ll be able to do it in that [full-time] capacity again, I don’t think I’ll be able to put my family through that again”.
