Luta Livre (also referred to Luta Livre "Brasileira", "Submission" or "Esportiva") is a Brazilian submission wrestling style, developed in Brazil in the 1920s by catch wrestling practitioner Euclydes "Tatu" Hatem, including techniques from Catch Wrestling, Judo, Wrestling and Brazilian jiu-jitsu. Luta Livre is divided in the categories of "Esportiva", which is a form of submission grappling, differentiating from no-gi BJJ with its focus on quick and energetic submissions, and "Vale tudo", which includes strikes both standing up and on the ground in addition to grappling and submissions. Luta Livre was important to the development of Mixed Martial Arts, as rivalry between BJJ and Luta Livre fueled the Vale tudo scene. However, the success of Brazilian Jiu-Jitsu over Luta Livre practitioners, especially after the "Desafio: Jiu Jitsu vs Luta Livre" event in 1991 (which was broadcast live by Rede Globo), resulted in the style waning in popularity, although it seems to be making a resurgence, especially as an alternative to both Brazilian Jiu-Jitsu and Catch Wrestling. Some notable Luta Livre practitioners in MMA include: Marco Ruas, Eugenio Tadeu, José Aldo, Alexandre Franca Nogueira, Terry Etim and Darren Till.
