Giacobbe "Jake" LaMotta was an American professional boxer who was world middleweight champion between 1949 and 1951. Nicknamed "The Bronx Bull" or "Raging Bull", LaMotta was a rough fighter who was not a particularly big puncher, but would subject his opponents to vicious beatings in the ring. With the use of constant stalking, brawling and inside fighting, he developed a reputation for being a "bully"; he was what is often referred to today as a swarmer and a slugger.
