History
Luta Livre is a Brazilian grappling art from Rio de Janeiro, created in the 1920s and 1930s by Euclydes "Tatu" Hatem from catch wrestling. It is trained without the gi and mixes takedowns, ground control and submissions, with a "vale tudo" version that includes strikes.
For decades Luta Livre was the great rival of the Gracies' jiu-jitsu, and the 1991 "Desafio" event between the two styles became legendary in Brazil.
