Founded by former Blackeye Promotions Vice President Janet Martin and longtime mixed martial arts executive Shannon Knapp in 2012, Invicta Fighting Championships was created as a showcase for female mixed martial artists following Zuffa’s purchase of Strikeforce. Invicta has promoted 27 events since its inception.

Invicta 1 on April 28, 2012 featured a main event that pitted former Strikeforce champion Marloes Coenen against Romy Ruyssen, with Jessica Penne, Liz Carmouche, Leslie Smith and 2008 Olympic bronze medalist Randi Miller also on the card. Miller defeated Mollie Estes by third-round technical knockout in her professional MMA debut. Nearly six years later, Invicta has become the largest female-only MMA organization in the world.

Mizuki Inoue will meet Virna Jandiroba for the vacant strawweight crown in the Invicta 28 headliner this Saturday at Union Event Center in Salt Lake City. The winner will join an exclusive group of fighters who have captured Invicta Fighting Championships gold:
