Jujitsu is an umbrella term for Japanese styles, with a Samurai lineage. Judo is a specific style of Jujitsu that focused on training safely with resistance, and evolves based on the results of training with resistance.
Brazilian Jiu Jitsu (BJJ) was developed in the early 20th century by Mitsuyo Maeda, and focuses on grappling and ground fighting. BJJ is considered a combat sport and a self-defense system and uses submission holds, joint locks and choke holds to subdue the opponent. It is a very effective style in which a fighter can use little to no strength to subdue a much larger opponent.
