The Engineering of Soviet Sambo (1923–1964)
The story of SAMBO (SAMozashchita Bez Oruzhiya—"Self-Defense Without Weapons") is a saga of both tradition and engineering. It was born from a desperate, utilitarian need: to provide the Soviet state’s security forces with a vetted, repeatable method of combat that could be scaled across an empire.
In the early days of the USSR, unique—and often brutal—conditions provided the laboratory for this new science. Sambo is a truly synthetic system; it represents multiple branches of a stream that eventually converged into a mighty, unstoppable river. It was borrowed, built, and tinkered with by men separated by thousands of miles, yet linked by a common, high-stakes goal.
However, Sambo was not just "built"—it was survived. Its creators were visionaries who had to navigate the treacherous political waters of the Stalinist purges, where a connection to the "wrong" foreign influence could lead to an unmarked grave. This is the history of the men who engineered a national identity through the mechanics of the human body.
What follows is the pragmatic history of Sambo’s development, from its dual origins to its emergence as a global combat sport. I have tried to draw a comprehensive picture of Sambo's origins through the stories of the men that contributed to the development of Sambo; typically only three names are associated with the founding Sambo but I believe that glosses over the true story. I have expanded the story by including sections on: Oznobishin, Vasilyev, Shkolnikov and Chumakov... men who are rarely mentioned but who played a critical role in developing the unique art as we know it today.
1. Before SAMBO
The history of Sambo begins in the early 1900's, with the Soviet Secret Police and the creation of the Dynamo Sports Club; which was essentially a sports club for the military and secret police.
Officially established in Moscow in April 1923, under the initiative of Felix Dzerzhinsky, founder of the Soviet secret police (NKVD); the Dynamo Sports Club was created as a physical training organization for the state's security and military athletes. It was the first Soviet departmental sports society, promoting "power in movement" for a new socialist culture. As such the main purpose of the Dynamo was to use sports for political indoctrination and athletic training and to foster a physical culture among security personnel. By September of that same year, the concept of the Dynamo spread across the Soviet Union. Eventually the Dynamo housed over 45 sports and had over 6000 locations. Notably one of the original members of the Dynamo was Viktor Spiridonov, who began producing systemized hand to hand manuals for the secret police to use; but he was not the first...
N.N. (Nil Nikolay) Oznobishin is not often a name brought up when discussing the formation of Sambo, and in some regards his accomplishments are often times attributed to Viktor Spiridonov. But we'll see that he was instrumental and that in many ways he was out maneuvered politically by Spiridonov and hence erased from Sambo's history. Nil Oznobishin was an established trainer and instructor in specialized unarmed combat techniques for the NKVD prior to the establishment of the Dynamo.
By 1930 his manual "The Art of Hand-to-Hand Combat" was the gold standard within the NKVD. Oznobishin had moved away from the idea of a "match" or a duel that was the standard thinking of the time and instead took a total "anything goes" approach to fighting instead. He is credited with developing the first integrated tactical model of combat: based on six distinct engagement ranges. His system ensured that a practitioner could operate seamlessly across all distances, from the use of firearms and striking to clinching and ground-level control. It was a comprehensive mix of Savate, English Boxing, and Jiu-Jitsu. His system was truly ground breaking at the time, and set the stage for Sambo later on, but his system required a good deal of athleticism; which Spiridonov saw as a limitation; it was also built from non-native martial arts systems- something that may have cost him later on. However his work was noticed by and certainly an inspiration for Viktor Spiridonov...
Already an author of two pre-Soviet hand-to-hand manuals: one focused on self-defense and arrest (based on the pre-Soviet Police system) and the other on Finnish-French Wrestling (Greco-Roman wrestling) of which he was quite capable; in 1927 Viktor Spiridonov began producing his own manuals on hand to hand combat for the Dynamo/NKVD. Spiridonov was noted for his athleticism and had experience in real world combat however as a WW I veteran on the front lines of Germany he suffered a bayonet wound to his left shoulder. It was also during his time in Germany though that he was exposed Jujutsu, of which he began a self study.
After the war and upon returning to Moscow Siridonov began arranging competitions at the Dynamo between the the German and Russian Jujutsu athletes. These competitions informed his work but he began to realize that the politics of promoting foreign systems as superior to native self-defense systems was becoming politically dangerous and he began to adjust his manuals accordingly: as can be seen in the titles below; with his first manual explicitly labeled as a system of Jujutsu, but just one year later the term "Samoz" was being used: an early acronym used to describe self-defense . It was this pragmatic shift to appeal to the national identity, as well as his influential connections at the Dynamo (which even held a competition of the Spiridonov system in February 1929) that directly lead to the name "SAMBO". The idea of a completely native Soviet system of hand to hand combat system was the start of Oznobishin being supplanted within the NKVD's 'Self-Defense' power structure. It should also be noted that the Spiridonov system was also much easier to learn than Oznobishin's. It was a striped down method that focused on simple restraints and standing joint locks. It was designed for "secret agents" and designed to even be preformed by injured soldiers (Spriridonov using his own injury as a testament). To illustrate how simplistic his system was: it only contained four takedowns: a shoulder throw with arm lock, a double leg grab, a fireman's carry (used against a gun held to the chest), and a rolling sacrifice throw used against a front choke. This was in stark contrast to Oznobishin's flashy system. Although curiously Savate Kicks did still manage to find their way into later SAMBO manuals.
Spiridonov's manuals: notice the names change to reflect the nationalist nature of Soviet politics.
"Manual of self-defense without a weapon in Jujutsu System" (1927): His first detailed publication which outlined the initial principles of his system.
"Self-defense without weapons. Training and competitions" (1928): Focused on training methods and the competitive aspect of his system within the Dynamo sports organization.
"Self-defense without weapons. Fundamentals of self-defense. Training. Methods of Study" (1933): A comprehensive manual that solidified his teaching methods, often referred to within the context of early "Combat Sambo"
2. Judo comes to Russia
While Spiridonov reigned supreme in the NKVD, he eventually had to share the spotlight with Vasili Oshchepkov, a Red Army Judo black belt from the Kodokan.
Vasili Oshchepkov was the first Russian and one of the first Europeans to earn a black belt in Judo under its founder, Jigoro Kano at the Kodokan in Japan. His early life is quite remarkable: born in 1893 on Sakhalin Island: his mother was a convict sentenced to hard labor. Her sentance took a mighty toll and as a result he was soon orphaned. At 8 years old he was placed under the guardianship of Amelon Vladik who sent him to a four year private school in Alexandrovsk; but following the 1905 Treaty of Portsmouth, which transferred part of Sakhalin to Japan, he was sent to Japan for Seminary Training. This training took place under Archbishop Nikolai at the Tokyo Orthodox Theological Seminary. While there he learned Japanese and later, after a very intense tryout, began training in judo.
Upon returning to Russia's far east in 1914 after finishing Seminary, he began work as a translator, first as a boarder guard and later in counterintelligence for the Amur Military District. He also began teaching Judo to the local police out of the pacific fleets sports club. In 1915 he hosted the first international Judo tournament between his students and students of the Japanese Higher Commercial School Otaru. A historic event in Judo history.
For several years he continued to visit Japan, receiving his second degree black belt in 1917, although he wasn't visiting as a student anymore... he was now working as an intelligence officer collecting intel for the Red Army (this was work that would come to impact his life in unpredictable ways later on.) Over the next decade his Judo style and teaching methods spread through the Red Army's Dynamo; it was also during this time that he had made contact with the ruling Communist Party in Moscow, which he would leverage to arrange a transfer to the Moscow Dynamo.
Once stationed in Moscow he continued to spread his Judo teachings, and by 1929 he became an snstructor at the Russian State University of Physical Education. In his new role he expanded his own understanding of the Martial Arts. He studied the bayonet, national forms of wrestling and Chinese martial arts. Oshchepkov took a "use-what-works" approach, stripping away traditional Judo kata and adding in the usable aspects of these other arts to create a martial art better suited for war-based combat. In 1930, Oshchepkov authored and published "Guidelines for the physical preparation of the Red Army,"" and in 1931 - the textbook "Exercise of the Red Army, where for the first time a program was set for a comprehensive program of training fighting members of the Red Army. At this point it is worth noting that the main techniques of these systems still looked like: JUDO (and bayonet fencing). Although it was a practical Judo, the dynamic style we know today was not yet developed- that happened later.
In the years until his arrest (accused of being a Japanese spy) and probable execution in 1937 Oshchepkov taught many....and mentored several notable students who would carry on his work and teachings, both to protect Judo and to bring SAMBO to the forefront of national sports.
And while Oshchepkov and Spiridonov were rivals, their systems eventually found their way into the same manuals. Although Spiridonov was against combining the systems; the shared environment of the Dynamo with their shared students, eventually lead to both systems being categorized together...and with that the name SAMBO became an umbrella term encompassing the techniques of both men.
3. The Lasting Influence of Oshchepkov: His Students
A New Style Emerges
The late 1930s were a period of extreme political risk and deadly nationalism. When Vasili Oshchepkov was arrested and lost to the purges , his foreign Judo based system faced erasure. Thankfully due to the work of his students, his teaching not only survived, but grew in scope and influence.
After Oshchepkov passed away in 1937, his star pupil, Anatoly Kharlampiev, sought to protect their work by rebranding his mentor’s Judo style as 'Freestyle Wrestling.' He fabricated a narrative that "Freestyle Wrestling" was an indigenous creation born from the folk styles of the Soviet republics. By claiming to be the sole architect of this "new art," he effectively erased both Japanese Judo and Oshchepkov from its official history. To avoid confusion with the Olympic event of the same name, Kharlampiev eventually adopted Spiridonov’s generic acronym for "self-defense without weapons": SAMBO.
This rebranding and new origin story provided the political cover necessary for Sambo to be recognized as the Soviet national sport in 1938. Despite this public erasure, evidence suggests Kharlampiev remained privately loyal; he maintained a good relationship with Oshchepkov’s widow, who reportedly entrusted him with her husband’s journals to complete his work. Furthermore, while other students famously cut Oshchepkov out of training photos to distance themselves, Kharlampiev kept his original photos intact, quietly acknowledging his true lineage.
During this same period, another of Oshchepkov's students, Ivan V. Vasilyev, served as a "combatives investigator" for the Red Army. In this role, Vasilyev reconciled the disparate systems of Spiridonov and Oshchepkov, transforming Sambo from a collection of theories into a repeatable curriculum for thousands of conscripts.
Working in tandem with Kharlampiev’s rebranding, Vasilyev stripped away the Japanese terminology and Zen philosophical overtones of Judo. He replaced them with a Soviet scientific framework, renaming techniques based on their biomechanical functions—for instance, replacing the Japanese Uchi Mata with the descriptive Podhvat (inner hook/pick-up).
Vasilyev’s work also began to minimize the influence of Spiridonov, whose techniques were tailored for secret police and special agents. For the average soldier, the "nuts and bolts" Judo and bayonet-driven style of Oshchepkov was more practical. This shift away from Spiridonov’s methods accelerated in the mid-1960s, as many Soviet special units began adopting the hard-hitting techniques of Kyokushin Karate as their primary hand-to-hand basis.
- Total Wrestling: Blending the crouched leg attacks of indigenous folk styles with the upright posture of Judo.
- The Half-Second Rule: A mandate for continuous aggression that eliminated the "reset" between standing and ground phases.
- The Fulcrum-Based Attack: Using the physics of levers—expressed as F1D1=F2D2 —to bypass traditional defense. By attacking submissions as a continuation of the takedown, Vasilyev turned Sambo into a sophisticated whole that was truly greater than the sum of its parts
R.A. Shkolnikov, another standout disciple of Oshchepkov, provided the final technical piece of the puzzle by standardizing the Kurtka (jacket) and Sambovki (shoes). This was more than a uniform change; it was a critical turning point in the sport's evolution.
The kurtka was designed for the rigors of multi-style wrestling. Its thick lapels and reinforced shoulder "wings" (epaulettes) were specifically engineered to withstand the violent gripping of folk wrestling, while the belt—woven through loops in the jacket—prevented the garment from being pulled over the head during high-amplitude throws.
Simultaneously, the introduction of sambovki (soft-soled leather shoes) fundamentally altered the footwork and entries. Shoes provided the traction necessary for the crouched, explosive leg attacks of the Leningrad school, further distancing Sambo from the barefoot traditions of Japanese Judo.
Beyond equipment, Shkolnikov was a tireless architect of the sport’s infrastructure. He was instrumental in spreading Sambo to Ukraine, establishing a powerhouse of talent in Kyiv that would eventually rival the original Moscow and Leningrad schools.
4. The Lasting Legacy: E.M. Chumakov '100 Lessons'
The Professor of Sambo
After WWII, Evgeny M. Chumakov emerged as the system’s technical guardian. A star student of Kharlampiev and a champion athlete in his own right, Chumakov became the first to earn a PhD in Sambo education. He authored the master text, 100 Lessons of Sambo, which remains the "gold standard" for instructors.
Chumakov’s greatest contribution was the "Chumakov Spiral," The Chumakov Spiral is very similar to the traditional Japanese concept of Shu-Ha-Ri, but with a Soviet emphasis on "Physical Culture" and measurable progress. It’s the reason Sambo practitioners are often noted for their "High-IQ" grappling—they aren't just memorizing moves; they are studying the tactical architecture of the entire sport. His pedagogical model requires students to revisit foundational techniques at four increasing levels of complexity:
- Raw Biomechanics: The isolated mechanics of the move.
- Dynamic Movement: Executing the move while in motion.
- Tactical Setup: Learning the setups and entries
- High-Stress Execution: Applying the technique in live, situational sparring.
This ensured that students viewed techniques through a new lens of experience at every stage of their development. He also introduced the concept of TTA (Technical-Tactical Actions), teaching that there were no "tricks"—only proper techniques applied through sound tactics based on grips, physical attributes, and situational awareness.
The Olympic Shift
Despite his deep Sambo credentials, Chumakov was famously direct about his roots. When asked what sport he practiced both before and after WWII, he answered without hesitation: "Judo." While it may seem contradictory for a man with a PhD in Sambo to claim Judo, his answer was rooted in the shifting political landscape of the 1950s: just 20 years earlier this answer could have landed him in a gulag just like Oshchepkov.
But by the mid-1950s, the Soviet Union was joining the Olympic movement. Because Sambo was not an Olympic event—and would not hold its own World Championships until 1976—the state’s resources shifted toward Judo in preparation for the 1964 Tokyo Games. Under the Soviet system, athletes and coaches earned considerably more prestige and financial support by winning at the World and Olympic levels. Consequently, most Dynamo clubs converted to Judo or adopted a dual-track system. For Chumakov and his contemporaries, training in both styles was a pragmatic necessity for success in the new Olympic era.
Because this information is very rarley (if ever) presented in English here is a more complete breakdown of the Chumakov Spiral:
Chumakov realized that a wrestler’s growth isn't linear—it’s a recurring loop under increasing pressure. He rejected the idea that a student "learns" a move and moves on. Instead, he used a four-stage refinement process:
Stage 1: Basic Biomechanics
The student learns the "static" mechanics. Where does the foot go? How do the hips rotate? Raw physics of the lever and the fulcrum.
Stage 2: Dynamic Entry (Movement)
The technique is practiced while both athletes are moving. The focus shifts from "how to throw" to "how to find the moment to throw."
Stage 3: The Tactics and Setup
The student learns to provoke a specific reaction. If I pull Left, he will resist Right; I use that resistance to fuel the throw. This is the "Technical-Tactical Action" (TTA) in its purest form.
Stage 4: High-Stress Situational Execution
The technique is applied under fatigue, against a resisting opponent, or in specific "worst-case" scenarios (e.g., down by two points with 30 seconds left).
The TTA (Technical-Tactical Actions) Framework
Chumakov’s PhD work essentially "de-mystified" the martial arts. In his view, there were no "secret moves," only variables. He categorized every match into a series of data points:
Grip Dominance: Who controls the sleeves and lapels?
Stance Differential: Is it a "Lefty vs. Righty" matchup?
Energy Efficiency: Is the athlete "spending" more effort than the opponent?
The results: By the 1960s, this scientific approach allowed Soviet coaches to "scout" international Judo opponents with terrifying accuracy. They didn't just train harder; they analyzed the biomechanical "tells" of their rivals and built specific counters for them.
