Brazilian jiu-jitsu
Brazilian Jiu-Jitsu was first developed and modified in the 1920s by Brazilian brothers Carlos, George, and Hélio Gracie after Carlos was taught traditional Kodokan Judo by a travelling Japanese judoka (Mitsuyo Maeda) in 1917, later going on to develop their own self defence system named Gracie Jiu-Jitsu.
