Jiu-Jitsu is a strategic, relatively nonviolent, highly effective martial art. Brazilian Jiu-Jitsu, as we know it today, was developed by Carlos Gracie Sr. and his younger brother Helio who further refined the art. Helio took the art of Jiu-Jitsu from it's original form which relied heavily on take downs and throws, to instead an art form that caters to the weaker and smaller person. Brazilian Jiu-Jitsu evolved into an art form that does not rely upon strength and size to defend against a bigger stronger attacker but instead uses a combination of techniques that utilize leverage and joint holds to stop and neutralize the attacker. The would be victim is able to control the attacker without the use of punches, kicks, elbow or knee strikes. As you can see, this is what makes Jiu-Jitsu the gentle art.
