Krav maga is a self-defense system developed in Israel that incorporates techniques from boxing, muay thai, judo, and wrestling. It was created by Imi Lichtenfeld in the 1930s in Bratislava to defend the Jewish community from fascist attacks. Krav maga focuses on real-world self-defense and efficient, devastating counterattacks. It was later incorporated into the Israeli Defense Forces' training to teach soldiers how to incapacitate opponents quickly and survive violent encounters.
