Nauka, “The Science,“ is a fighting style from Serbia. It is worldwide used for Personal Protection, Defensive Tactics and Military Combatives so people can deal with violence.

Since its origination in 1910, Nauka has had one major goal – to defeat enemies in the best possible way, whether they are criminals, soldiers, terrorists or other threats. Another important aspect is the positive effect on mental and physical health. So in general, Nauka is about the expansion of honorable values and getting home safely at the end of the day.

Violence is a part of our nature and has always been with us. Most people in our societies understand its consequences and try to avoid it. The problem starts with ignoring violence, because some people will exploit this. When violent acts occur to people who have always ignored it, they are mentally overwhelmed by the situation and are not able to respond properly. This can be life threatening.

Nauka was born and raised in the streets and battlefields of Europe. Therefore, Nauka knows the problems of violence and offers a complete training. It uses centuries-proven war arts and adapts them to the conflicts of our time. To successfully protect against modern violence, one must first understand it and you better know the environment in which you move, because this is the environment in which you will have to defend yourself. Street mentality is a world unto itself. It has its own languages, cultures, rituals and rules. Not for nothing is such an environment called the „Concrete Jungle“.

Nauka focuses on the cultivation of intelligence, emotion and instinct, while using simple movements. It works as an update of innate human protective mechanisms. This keeps it functional in extreme situations, where highly demoralizing conditions are involved, like fatigue, improper gear and equipment, unfamiliar and varied terrain, injuries, emotions, armed and multiple opponents.

A major strategic concept is the Nauka Conflict Matrix, which emphasizes 5 solutions to deal with conflicts. Each phase has its own sub-sections and special training methods. A Naukan will learn things like avoiding potential conflicts, prevention and preparation, timely exit of conflicts, rapid escape, exploration of safer places, confidence and strong outside appearance, verbal de-escalation and commands, first aid, necessary escalation and proper use of violence (worst case). Nauka is divided in Combat (fighting and defense), Survival (Skills for extreme situations) and Tradition (historical culture and martial arts).



From ancient times until today, people like to surround themselves with like-minded people. Members of the Naukan Clan, or “Naukans“ are no different. They form a worldwide family of brothers and sisters united in the Nauka Clan, where freedom and community are preserved through loyalty and respect.

The Nauka Clan is deeply rooted in the chivalry of the Serbian culture, as this is the founders’ personal heritage and their source of power through their own history. We also believe in human nature and that a person can do good or evil things in life without any connections to their origin. We actively seek out people who are doing good things and have a positive outlook on life. As a Naukan, you must be open-minded and respectful to other Naukans. All cultures are welcome. As we have all experienced suppression in our history and in our societies, we do not tolerate cultural, racial, religious, political, or gender-related suppression or discrimination in our Nauka Clan. Although occasional jokes might come from other Naukans, nothing is meant to be disrespectful. In the end, we are all part of the same Clan – We are Naukans.

The Nauka Clan offers a great network, where Naukans are helping out other Naukans, whether in their private or in their working life. Everybody has something he or she is good at and it helps to talk to experts from different professions to share experiences. In addition to ordinary civilians, Naukans consist of professionals across all sectors, such as companies, organizations, law enforcement, military, rescue services, security services, schools, celebrities, sports athletes, stuntmen and many more. Every Naukan profits from the Clan and every Naukan can give back to the Clan. This is our strong community.

Nauka Clan Members are wisely chosen. Traditionally, this comes from the strict rules in the Communist Era in Yugoslavia, but also from older times under different terrible occupations. The Nauka ancestors had to be clandestine about their heritage. Their culture, their faith and their Nauka Fighting Style were all practiced in secret. Today we are free to do what we want, but we still keep this tradition, as we do not want the wrong people in our Clan.

Nowadays, we live faster and faster, with more tension, less time and more threatening violence in between. The Nauka Clan serves as a stronghold for like-minded people, who share honesty, respect and loyalty. Naukans regularly come together for meetings, parties and other events. They are also involved in many chartity projects, to help those who need it. Naukans live as heroes of their own life.

The unity of the Nauka Clan is represented by the “Nauka Bear Paw” Logo. Even though Naukans have a different origin, they share the same attitudes, as well as their passion for the Nauka Fighting Style and their Nauka Clan. They identify with the logo on flags, clothes, patches and other media.



Our Symbol and Coat of Arms is the “Nauka Bear Paw” and is explained like this:

  • In Slavic mythology, the bear is a very special animal, through its calmness and strength.
  • 5 conflict solutions concentrated in one direction (Conflict Matrix)
  • The human body is symbolized by the large part of the paw. The claws represent the 5 weapons of the body – the legs, the arms and the head.
  • Someday someone said about the family: “These gentlemen are like bears. They go their own way, which you better should not block!”

Freedom and health have always been the highest desires of man. However, since they are always in danger, they have to be constantly protected. So it was in this history.

Serbia in 1910: A young man, Blagoje Stojanović, successfully participated in the family business of wine trading. During this time, he and his people traveled by horse and carriage and by foot through the countless roads, forests, mountains, taverns and ports in the Balkans and in Europe during the early 20th century. These trips were very dangerous and one could easily become a victim of bandits and assassins. They were faced with numerous attacks, but one day, the bandits killed many workers and wounded Blagoje. He was left for dead, but he survived. The wounds healed, but the incident made him think deeply about how to defend himself in such situations. So he began his research.

His father was a war surgeon and fought in the Balkan Wars from 1912 and 1913 to liberate the country from foreign rule. The family had deep roots in the Hajduk culture (asymmetric warfare and survival tactics) and participated in different engagements, like the famous Battle of Čegar, with a direct frontline through their village. These facts were a dwell of knowledge.

Soon after, in 1914, the First World War began and he had to fight as a Soldier to protect his life, his family and his country. When he came back from war, Blagoje had already developed a method to defend himself. He leaned on his passion for the old Slavic folk martial arts, the tactics of the Hajduk resistance fighters, his experiences from the war and his travel adventures. The style worked against multiple opponents, in all positions, under any circumstances, with or without weapons. His internal strength came from his faith, and he protected his life with his fighting style, which had no name yet.

Other people appreciated his skills and wanted his protection on the road. By this time, he gained respect from good and bad guys alike in the Balkans and some Ottoman bandits gave Blagoje his nickname „Belaj“, which means „Trouble“.

He passed his teachings to his son, who made his own experiences and after his return from the Second World War, he passed it on to his sons. The style has been constantly evolving and was notorious for its effectiveness. In the time of the Regime in Yugoslavia, there was a strict ban on martial arts and only the military and the police was permitted to train them. In order to not attract attention, but still continue their traditions, they met secretly, chose their training partners very carefully and devised a code name to speak of it: naša nauka – “our science.“

From this code word derives the current name of the style – Nauka.
The manner of selecting members, has been unchanged to this day. Fortunately, the training is no longer forbidden, but by that it is sure that not the wrong people are trained and there is a common respect shared among the group.

Beside all the hard proofs of life through which Nauka led the family, it always was and still is important for them to live like gentlemen. Honor and respect are the highest values and an important part of Nauka.

So today, the latest generation of the Stojanović family holds up the proud tradition of their ancestors and shares it with others so they can protect and enhance their lives, too.

In the year 2010, after exactly 100 years of exclusive family tradition, the Nauka Fighting Style was made publicly accessible and continues to save lives worldwide.



“To successfully defend against something, one must first understand it.” Nauka Codex

The Nauka Fighting Style was developed progressively over more than a century. Again and again it has proved in practice. The main influences of Nauka are:

  • Slavic Martial Traditions
    Martial Arts of the Slavic Warriors and Knights • Boxing • Wrestling • Fencing • Body Strengthening • Health and Healing Arts • Chivalry
  • Underworld Methods
    Fighting Methods used by Smugglers, Bandits and Assassins • Street Mentality • Duels • Codes • Prison Tactics • Criminal Mindset and Behaviour
  • Military Combatives
    Hajduk Resistance • First World War • Second World War • Communist Yugoslavian Era • Soviet Influence • Modern Training Technology
  • Research and Development
    Various Sciences • Statistics • Testing • Analysis • Learning from Mistakes • Open Mind • Creativity


The Nauka is a well-kept tradition. Originally created to protect the lives of the family members, it was only passed on from father to son. Until today, Nauka has saved many lives and kept the family members on the right track (or brought some back on it). The Nauka Clan decided to share the family tradition with the world, so other people can protect themselves as well.

The growing number of interested Nauka Students requires a qualified education. So a worldwide unique Ranking System was formed for those who want to progress in Nauka. All Nauka Ranks carry a Slavic title in addition to the English title.

As a Nauka Clan Member, you can take part in the Ranking System and you can get an own Nauka Identity Book to document your Nauka journey.



Experience is one of the most important factors to be able to grow in Nauka. The progression within Nauka is visualized by the Nauka Experience Points (NXP). They can be earned by attending the different types of Nauka training. By reaching a certain amount of NXP, one has earned a Nauka Student Rank. The types of training that provide NXP: Seminars, Battles, Personal Training, Regular Training, time as a Nauka Teacher and relevant Training outside of Nauka.

Nauka Student Ranks are milestones on the path of collecting Nauka Experience Points (NXP). Each Nauka Student Rank stands for a certain amount of NXP one has reached and the Student continues the collection to reach a higher step. A Nauka Student can become a Nauka Scout and create a Nauka Outpost (Training Group).

The NXP and Student Ranks are endless, as well as experience is endless. The Nauka journey begins with Nauka Student Rank 0 and to be allowed to begin, the Student has to express the will to start, to be accepted and to swear the Nauka Oath to a Nauka Teacher.



Becoming a qualified Nauka Teacher will not be easy, as we want you to get an excellent education and to be able to teach high-level self-defense with Nauka. Your students` lives may depend on this! You can only learn the traditional way – hard training with qualified Nauka Teachers.

There is only one Teacher Rank in Nauka. After earning it, one has a solid base in the Nauka material. To continue the progression, a Nauka Teacher focuses on the Nauka Sectors. Every Sector is a specific topic and contains multiple, related Nauka Modules one can master.

To become a Nauka Teacher, one needs to collect NXP and Student Ranks, as well as the acceptance of the Nauka Clan Chief. All Nauka Teachers remain Nauka Students and continue the journey.
