John L. Sullivan was so special that he made gloved boxing, the type of boxing we watch today, a popular national and international money-making sport. He was the man who started gloved boxing on its path towards acceptance in the sporting world as the form of fighting that could determine a true champion. He boasted that he could knock out anyone within 4 rounds, and he was good enough to do it; inspiring awe in all those who saw him. John L. Sullivan was the world's first sports superstar. Still, in order to convince skeptical old-school fight purists of his right to be called champion, Sullivan occasionally had to engage in bareknuckle contests under the traditional London Prize Ring Rules. The only problem was that fighting, and especially bareknuckle fighting, was illegal. This book follows Sullivan's career path, fight by fight, blow by blow, in glorious detail, using local next-day primary sources. Also covered is Sullivan's personal life, training, negotiations, legal battles, and all of the extracurricular activities outside the ring that helped make him the world's most famous man. The 490 page book contains over 200 rare contemporary lithographs, drawings, photographs, and advertisements.
