Rousey fought Liz Carmouche at UFC 157 on Feb. 23, 2013, in the first women's MMA fight in the UFC. She won via first-round submission (arm bar, of course) and then successfully defended the belt five more times. Along the way, Rousey became one of the biggest stars in the sport.
At UFC 193 in Australia on Nov. 14, 2015, Holm did the unimaginable: She destroyed Ronda Rousey and took the title from her.
Holly Holm made her first title defense at UFC 196 on March 5 against Miesha Tate. It would be her only fight as champion, as Tate submitted Holm with a rear-naked choke in the fifth round.
In the main event of UFC 200 on July 9, Amanda Nunes put an end to Tate's reign as champion. Nunes beat Tate via first-round submission (rear-naked choke) to become the new champion.
