Along the way, the success of Rousey gave UFC president Dana White the green-light to move ahead with more female divisions in the promotion.
Rousey’s run would be toppled by Holly Holm, with Amanda Nunes now laying to the crown of best fighter in women’s mixed martial arts.
Along with Rousey, Holm and Nunes, Miesha Tate is the only other athlete in the UFC to hold the title.

For almost 1,400 days, Amanda Nunes has been the UFC’s female bantamweight champion.
Nunes won the title with a dominating performance at UFC 200 in the marquee bout in Las Vegas, stopping Miesha Tate.
She would go on to finish out the year with another near-perfect victory against Ronda Rousey, cementing her status in the division.
Nunes followed up with a 2017 victory over Valentina Shevchenko, a win in 2018 vs. Raquel Pennington and triumphs last year over both Holly Holm and Germaine de Randamie.
Along with being the bantamweight champion, Nunes also holds the featherweight title.
On March 5, 2016, Miesha Tate earned the biggest win of her career when she submitted Holly Holm at UFC 196 in Las Vegas to win the title.
Tate, who had tried in the past to win the belt vs. Ronda Rousey, held the title for 126 days.
A world boxing champion, Holly Holm put her focus on mixed martial arts.
It all came together for Holm in Melbourne, Australia at UFC 193 on November 15, 2015 against Ronda Rousey.
Holm walked into the Octagon as the challenger, and exited as the UFC female bantamweight champion and one of the top combat sports athletes in history.
She finished Rousey, but would only hold the title for 111 days before losing to Miesha Tate.
The force in female MMA for the span of three-plus years, Ronda Rousey was presented as the first-ever UFC female bantamweight champion when the division was created in 2012.
She held the title for 1,074 days and earned six title defenses along the way. More, her ability to generate interest in the sport helped the UFC create even more women’s divisions.
Rousey scored wins over Liz Carmouche, Miesha Tate, Sara McMann, Alexis Davis, Cat Zingano and Bethe Correia before falling to Holly Holm in 2015.
