 Krav Maga is a hybrid martial arts system developed by Emmerich Lichtenfeld. Lichtenfeld's background includes Aikido, Judo, Karate, and he was also a champion boxer and wrestler. Facing the rise of anti-semitism in Europe in the 1930s, he began to teach self-defense to his neighbors. Krav Maga means contact combat, and the objective was to strip down the arts to the core basic combat models and apply them in an explosive sequence. Once the confrontation occurs, the defenders taught that offense is the defense and to use the environment as a weapon and not stop until their attacker is rendered incapacitated. Tactical weapons were added, and Krav Maga was adopted as the official training for the IDF or Israeli Defense Forces. Combining elements of takedowns, weapons, strikes, and escapes, the goal of Krav Maga, when trained at a high intensity level, is to trigger a reactionary response that turns the defender into a wicked human hurricane.
