Amanda Nunes dethroned Miesha Tate in the first round to win the women's bantamweight championship at UFC 200.
The main event of UFC 200 was slated to be a light heavyweight unification bout between Daniel Cormier and Jon Jones. After a positive drug test, Jones was pulled from the card, prompting Miesha Tate's bantamweight title defense of Amanda Nunes to be the new main event.
It was a historic moment for women's mixed martial arts, considering women were headlining arguably the most historic card in UFC history after the company's president, Dana White, said women would never fight in the UFC.
Nunes put Tate in trouble early in the first round, unleashing a flurry of strikes and wobbling Tate. At one point Tate dropped and it looked like the fight would be stopped, but Tate escaped. Nunes continued to pursue and unleash strikes, Tate went to the ground to escape the grappling after she began to bleed from her face.
Nunes got Tate's back, opened her up with punches from the site and then sunk in the rear naked choke to force Tate to tap. It was the same submission Tate used to beat Holly Holm at UFC 196 and the women's bantamweight title belt changed hands for the third time since Holm defeated Ronda Rousey at UFC 193.
Nunes became the first woman from Brazil to hold a UFC title belt.
