When Imi Lichtenfeld came to British Mandate of Palestine prior to the establishment of the state of Israel, he began teaching hand to hand combat to the Haganah, the Jewish underground army. After the establishment of Israel, krav maga was the generic term used to reference the hand to hand combat taught to the Israeli armed forces and police.
When Lichtenfeld moved to Israel he changed his name to Sde-Or, a direct translation of his surname into Hebrew. Due to the fact that it is strictly a self-defense and military combat system, Krav Maga is constantly changing. After Mr. Lichtenfeld retired from a long career as chief instructor of close combat in the Israel Defense Forces (IDF), he started teaching Krav Maga to the civilian population. In this way, a civilian version based on the principles of self-defense was developed.
In 1973 The Krav Maga program of the IDF underwent significant changes, when Moni Aizik was asked to revamp and redevelop the system so that it was able to meet the needs of the Sayeret/Special Forces. Moni Aizik continues to teach this system under the name Commando Krav Maga, using the prefix 'Commando' to note that this system is the one used by Israeli Special Forces as opposed to general infantry.
Prior to 1985, all experts in Krav Maga lived in Israel. Many schools have opened outside Israel, with the instructors being certified by the Israeli Krav Maga Association. Since the death of Imi Lichtenfeld, a number of different schools and associations of Krav Maga have developed around the world. There is currently a controversy among various organizations and individuals who claim the mantle as Imi's successor.
In Krav Maga, there are no hard-and-fast rules. It is not a sport and there is no competitive component. All the techniques focus on maximum efficiency in real-life conditions. Krav Maga generally assumes a no-quarter situation; the attacks and defenses are intended to inflict or divert the most pain possible on the opponent. Groin strikes, headbutts, and other efficient and potentially brutal attacks are emphasized.
The guiding principles for those performing Krav Maga techniques are:
- avoid injury.
- go from defending to attacking as quickly as possible.
- use the body's natural reflexes.
- strike at any vulnerable point.
- use any tool or object nearby.
