Htoe Kwin tattoos. The traditional martial arts of Myanmar are regrouped under a term called "
thaing", which includes
bando,
banshay,
naban, shan gyi and Lethwei. According to researchers, thaing can be traced in its earliest form to the 12th century of the
Pagan Kingdom dynasty. In
Bagan, it exists some carvings on temples and pagodas in the central Myanmar plains, which appear to show pairs of men locked in combat, suggesting the sport is potentially over a thousand years old. In ancient times, matches were held for entertainment and were popular with every stratum of society. Participation was opened to any male, whether noble or commoner. At that time, matches took place in sand pits instead of rings. Boxers fought without protective equipment, only wrapping their hands in hemp or gauze. There were no draws; the fight went on until one of the participants was knocked out or could no longer continue. Back then, Burmese boxing champions would enter the ring and call for open challenges. Lethwei went through many years of suppression during the British colonial rule of Burma. The sport was revived under General
Ne Win's nationalistic government. Unlike Muay Thai, in Lethwei, punches are generally favoured over kicks because of their ability to draw blood more easily. Traditional matches include the
Flagship Tournament, which are still fought throughout Myanmar, especially during holidays or celebration festivals like
Thingyan. In rural areas, having a skilled child fighter has been a way of escaping poverty.
The New Era In modern times, the sport is kept alive in
Lower Burma in
Mon State and
Karen State where matches are held for events such as New Year's celebrations.
Kyar Ba Nyein, who participated in
boxing at the 1952 Summer Olympics, pioneered modern Lethwei by setting in place modern rules and regulations. He travelled around
Myanmar, especially the
Mon and
Karen states, where Lethwei is more actively practiced. After training with some of the fighters, Kyar Ba Nyein brought some to
Mandalay and
Yangon to compete in matches. In 1996, the
Myanmar Traditional Lethwei Federation (MTLF), a branch of the
Myanmar's Ministry of Health and Sports, added the
modern Lethwei rules for the occasion of the
Golden Belt Championship in
Yangon. The bouts, along with the undercard fights, were organized by the Ministry of Sport, Myanmar Traditional Lethwei Federation and KSM group. This marked a big addition to the art of Lethwei and potentially would make Burmese boxing more marketable internationally. On 18 July 2015,
ONE Championship held the first Lethwei fight in its history inside a cage at the occasion of
ONE Championship: Kingdom of Warriors in
Yangon, Myanmar. The fight showcased
Burmese fighters Phyan Thway and Soe Htet Oo in a
dark match and the result was a draw according to the
traditional Lethwei rules. In 2017,
ONE Championship and
World Lethwei Championship officially entered into a partnership to share athletes to fight in each other's organization. On June 30, 2017, ONE Championship held a Lethwei match at
ONE Championship: Light of a Nation between
Thway Thit Win Hlaing and Soe Htet Oo. Thway Thit Win Hlaing would end up winning a decision according to
WLC point system. In 2019, the
WLC marked history by broadcasting
WLC 7: Mighty Warriors, the first Lethwei event, internationally live on
UFC Fight Pass.
Opening to the world From 7 to 12 July 2001, twelve years after
Burma changed its name to
Myanmar, the first international event took place in Yangon with professional fighters from the
United States facing Burmese fighters under full traditional Lethwei rules. The delegation of three American fighters brought by the
IKF were
Shannon Ritch, Albert Ramirez and
Doug Evans. Ritch faced Ei Htee Kaw, Ramirez faced Saw Thei Myo, and Evans faced openweight Lethwei champion
Wan Chai. All three Americans lost to the Burmese. A revenge match with American and European fighters was cancelled the last minute by Lethwei promoters and the military in 2002. From 10 to 11 July 2004, the second event headlining foreigners took place with four Japanese fighters fighting against Burmese fighters. They were
mixed martial arts fighters
Akitoshi Tamura, Yoshitaro Niimi, Takeharu Yamamoto and Naruji Wakasugi. Tamura knocked out Aya Bo Sein in the second round and became the first foreigner to beat a Myanmar Lethwei practitioner in an official match. International matches continued with the exciting
Cyrus Washington vs. Tun Tun Min trilogy. In 2016, after having previously fought to an explosive draw,
Dave Leduc and
Tun Tun Min rematched at the
Air KBZ Aung Lan Championship in Yangon, Myanmar. The rematch was sweetened by an added bonus: ownership of the Lethwei Openweight World Championship Belt. Leduc became the first non-Burmese fighter to win the Lethwei Golden Belt and become Lethwei world champion after defeating Tun Tun Min in the third round. Following his title defence, Leduc said in an interview, "I have so much vision for this sport. I see Lethwei doing the same for Myanmar as what Muay Thai has done for Thailand." On April 18, 2017, for his second title defense under traditional rules,
Dave Leduc faced
Turkish Australian challenger Adem Yilmaz at
Lethwei in Japan 3: Grit in
Tokyo, Japan. On July 10, 2025,
Bare Knuckle Fighting Championship co-owners
Conor McGregor and David Feldman made a number announcements in
Hollywood, Florida. One of the announcements included acquisition of majority shares in a Lethwei promotion in Asia.
Sanctioning worldwide Due to the violent ruleset, Lethwei is difficult to sanction and is illegal in most countries outside of Myanmar. Even though headbutts are allowed in Lethwei, they are banned from most other combat sports including mixed martial arts, kickboxing, and Muay Thai. As of 2022, Myanmar Lethwei is only legal in the following countries:
Myanmar,
Japan,
Singapore,
Slovakia,
Austria,
Thailand,
Taiwan,
England,
United States (only the state of
Wyoming),
New Zealand and
Poland. The
World Lethwei Federation has the responsibility to sanction and support the growth of Lethwei worldwide outside of
Myanmar. == In popular culture ==
