Krav Maga[a] is a military self-defence and fighting system developed for the Israel Defense Forces (IDF) and Israeli security forces derived from a combination of techniques sourced from Boxing, Wrestling, Judo, Aikido, and Karate. Krav Maga is known for its focus on real-world situations and its extreme efficiency.

It was derived from the street-fighting experience of Hungarian-Israeli martial artist Imi Lichtenfeld, who made use of his training as a boxer and wrestler, while defending the Jewish quarter against fascist groups in Bratislava, Czechoslovakia, during the mid-to-late 1930s.

In the late 1940s, after his aliyah to Mandatory Palestine, he began to provide lessons on combat training to what was to become the IDF.
