Euclydes Hatem, born on September 16, 1914, in Rio de Janeiro, Brazil, and known by his nickname “Tatu” (Portuguese for armadillo), was a pivotal figure in the development of Brazilian martial arts as the founder of Luta Livre.
Of Lebanese descent, Hatem earned his nickname due to his stocky, muscular build, which belied his agility and technical prowess.
His contributions to martial arts, particularly through the creation of Luta Livre, a no-gi submission grappling system rooted in catch wrestling, left an indelible mark on Brazil’s combat sports landscape.
Here’s a timeline of Eucyldes Hatem’s life and his most iconic moments as a fighter.
Early Life and Introduction to Martial Arts
Euclydes Hatem was born into a family of Lebanese immigrants who were merchants in Rio de Janeiro. As a child, he struggled with weight, reportedly reaching 114 kg, which prompted his older brother, Eduardo Hatem, to encourage him to take up sports for fitness.
At age 14, in 1928, Hatem initially tried rowing but found it unfulfilling.
His true calling came when he joined the Associação de Cristã de Moços (YMCA) in Rio de Janeiro, where he began training in catch wrestling under the tutelage of renowned coaches Orlando Americo da Silva (“Dudú”) and Manoel Rufino dos Santos.
Dudú, in particular, was a legendary figure who had also trained Brazilian Jiu-Jitsu (BJJ) pioneers George and Hélio Gracie and defeated judoka Geo Omori. Under their guidance, Hatem quickly displayed exceptional talent, combining raw athleticism with a passion for grappling.
Development of Luta Livre
Hatem began his martial arts journey as a catch wrestler, competing in the rough-and-tumble grappling scene of 1930s Brazil. Catch wrestling, known as “Luta Livre Americana” in Brazil to distinguish it from Greco-Roman wrestling, allowed a wide range of techniques, including submissions, with few restrictions.
Tatum’s innovative spirit led him to experiment with new techniques, blending catch wrestling with elements of judo and other grappling arts. By 1927, he was teaching his evolving style in Rio de Janeiro, laying the foundation for what would become Luta Livre.
Luta Livre, meaning “free fighting” in Portuguese, emphasized no-gi grappling, focusing on takedowns, ground control, and submissions like chokes and leg locks. Unlike BJJ, which relied on the gi for grips and techniques, Luta Livre’s no-gi approach made it accessible to poorer communities, earning it the reputation as a martial art “for kids who couldn’t afford a gi.”
This accessibility fueled its popularity in Rio’s favelas, creating a cultural and class-based rivalry with the more elitist BJJ, practiced by wealthier, often lighter-skinned Brazilians.
Hatem’s system prioritized practical, effective techniques for Vale Tudo (“anything goes”) matches, early precursors to modern MMA. Luta Livre incorporated leg locks, which were largely ignored by BJJ at the time, and later included striking elements, evolving into two distinct styles: Luta Livre Esportiva (submission grappling) and Luta Livre Vale Tudo (allowing strikes).

Fighting Career and Notable Matches
Hatem’s competitive career spanned the 1930s to the early 1950s, during which he established himself as one of Brazil’s most formidable grapplers. Known for his mastery of chokeholds, he competed in catch-as-catch-can wrestling, professional wrestling, and Vale Tudo, often facing opponents from various martial arts disciplines.
Here are some of Tatu’s most iconic fights.

1935: Euclydes Hatem vs. Kutter (International Wrestling Championship, Brazil)
Hatem participated in Brazil’s first international wrestling championship, showcasing his skills against seasoned grapplers. He won the tournament by submitting veteran wrestler Kutter, solidifying his reputation as a top-tier competitor. This victory marked a significant milestone in his career and helped elevate catch wrestling’s status in Brazil.
1937: Euclydes Hatem vs. Takeo Yano (First Match)
Hatem faced Japanese judoka Takeo Yano, a colleague of Mitsuyo Maeda and hand-to-hand combat instructor for the Brazilian Navy. Despite having trained together previously, Hatem defeated Yano via chokehold in a highly publicized match. The victory highlighted Luta Livre’s effectiveness against judo, though Yano requested a rematch with a rule requiring Hatem to wear a judogi, giving Yano an advantage.
1937: Euclydes Hatem vs. Takeo Yano (Rematch)
In the rematch, Yano’s judogi rule allowed him to capitalize on Hatem’s lack of familiarity with gi-based techniques. Yano won after a hip throw caused Hatem to injure his shoulder, making him vulnerable. This loss was a rare setback for Hatem, who quickly resumed competing after recovery.
1940: Euclydes Hatem vs. Charles Ulsemer (Copa Mundial Benito Valladares)
Hatem competed in the Copa Mundial Benito Valladares, a prestigious tournament, and faced French wrestling champion Charles Ulsemer. In the qualifier, Hatem won the tournament, and in a subsequent match refereed by Oswaldo Gracie, he defeated Ulsemer via armlock. Ulsemer refused to tap, reportedly going unconscious, and the two became close friends afterward. Hatem was awarded the Valladares Governor Belt for his victory.
1940: Euclydes Hatem vs. George Gracie
One of Hatem’s most celebrated victories came against George Gracie, a prominent BJJ practitioner and member of the Gracie family. In a catch rules match, Hatem submitted Gracie with a rear naked choke in the second round, though some sources mistakenly claim it was an Americana lock due to a misleading newspaper photo from the first round where Gracie escaped. This win significantly boosted Luta Livre’s popularity and intensified the rivalry with BJJ, as it demonstrated Luta Livre’s superiority in no-gi grappling at the time. Brazilian promoters, wary of Hatem’s dominance, reportedly avoided arranging a rematch.
1947: Euclydes Hatem vs. Leon Falkenstein (“Homem Montanha”)
In 1947, Euclydes Hatem faced Russian super heavyweight Leon Falkenstein, nicknamed “Homem Montanha” (Mountain Man) for his 330-pound frame. Falkenstein proposed a worked (scripted) match, which Hatem refused, leading to heated public exchanges. In the match, Hatem defeated Falkenstein in just 37 seconds via submission. Falkenstein demanded a rematch after training with Vale Tudo fighters, but Hatem again won by submission, further cementing his dominance.
1947: Euclydes Hatem vs. Takeo Yano (Rubber Match)
After an unbeaten tour in Argentina, Hatem faced Yano again in a third match, winning by submission. This victory underscored his consistency and adaptability against high-level opponents.
Post-Retirement: Euclydes Hatem vs. Waldemar Santana (Challenge Match)
After retiring in the 1950s, Euclydes Hatem opened a gym to teach Luta Livre. Waldemar Santana, a former Gracie student known for defeating Hélio Gracie in a Vale Tudo fight, challenged Hatem at his gym.
Despite being in his 40s and retired, Tatu reportedly made quick work of Santana, submitting him with a choke, as witnessed by judoka and Luta Livre practitioner Hugo Melo.
This anecdote highlights Hatem’s enduring skill and reputation.Hatem’s career was marked by an undefeated streak in his prime, with victories over notable figures like Carlos Mesnik, Greek grappler Kostolias, and Luiz Stock.
He also competed in elite tournaments in São Paulo against international stars like Richard Schikat, Tom Hanley, Henry Piers, and Kola Kwariani, though restrictive rules banning chokes occasionally led to losses by pinfall. Despite these setbacks, Brazilian media consistently praised his skill and tenacity.
Retirement and Teaching Legacy
Hatem retired from competition in the early 1950s and focused on teaching Luta Livre at his academy in Rio de Janeiro.
His school became a hub for developing the next generation of fighters, including notable students like Euclides Pereira, Fausto Brunocilla, and Carlos Brunocilla.
Pereira, nicknamed “O Diabo Louro” (The Blonde Devil), became a legend in Vale Tudo, famously defeating Carlson Gracie in 1968, further fueling the BJJ-Luta Livre rivalry.
Tatu’s teaching emphasized technique over brute strength, a philosophy later refined by Roberto Leitão, a judoka and engineering professor who applied biomechanical principles to Luta Livre in the 1970s.
Euclydes Hatem’s system influenced modern no-gi grappling and produced world-class MMA fighters like Marco Ruas, Antonio Rodrigo Nogueira, Antonio Rogerio Nogueira, Renato Sobral, Pedro Rizzo, José Aldo, and Darren Till.
Luta Livre’s Rivalry with BJJ
The rivalry between Luta Livre and BJJ was not just technical but deeply cultural, reflecting Brazil’s class divides. BJJ, associated with the affluent Gracie family, contrasted with Luta Livre’s working-class roots.
Euclydes Hatem’s 1940 victory over George Gracie set the stage for decades of animosity, which peaked in the 1980s and 1990s with high-profile clashes, such as Hugo Duarte’s loss to Rickson Gracie on a Copacabana beach and Eugenio Tadeu’s defeat to Wallid Ismail in 1991.
These losses, along with BJJ’s global success through the UFC, contributed to Luta Livre’s decline in prominence, though it remains influential in Brazil and Europe, particularly Germany, where it was introduced by Daniel D’Dane.
Death and Legacy
Euclydes Hatem died on September 26, 1984, in Rio de Janeiro, leaving behind a legacy as a sports hero in Brazil. His creation, Luta Livre, played a crucial role in shaping modern MMA, particularly through its emphasis on no-gi grappling and versatile techniques.
The Confederação Brasileira de Luta Livre Esportiva, founded in 2017, continues to promote the art, and its structured curriculum and ranking system mirror those of BJJ and judo.
Hatem’s impact is evident in the success of his students and the fighters who carried Luta Livre into the MMA era.
While overshadowed by BJJ’s global dominance, Luta Livre’s contributions to submission grappling and Vale Tudo remain undeniable, with Euclydes Hatem’s innovative spirit and competitive achievements cementing his place as a pioneer of Brazilian martial arts.
