It is the martial art that makes the fight between David and Goliath possible; Brazilian Jiu Jitsu is based primarily on the premise that a small person can successfully defend himself against another person of greater size and strength.
It came to Rio de Janeiro, Brazil, in the early 20th century as a martial art derived from Kodokan Judo from Japan. From that point on it became the most popular combat sport in the country, later spreading to other countries in Latin America and the rest of the world.
The BJJ's main objective is to bring the opponent to the ground and subdue him through the correct use of combat techniques; levers, application of dislocations, grabs, throws and takedowns. The great variety of techniques and combinations makes it one of the most complete contact sports, being one of the most used in the practice of mixed martial arts and MMA.
One of the greatest virtues of BJJ is that it can be practiced by women and men of any age, being adaptable to the physical conditions of the apprentice; it's just a matter of perseverance.
