How many unsuccessful attempts did Mendoza make before becoming Champion of all England?
Boxing matches were very popular in England two hundred years ago. In those days, boxers fought with bare fists for prize money. Because of this, they were known as 'prizefighters'. However, boxing was very crude, for these were no rules and a prizefighter could be seriously injured or even killed during a match.
One of the most colourful figures in boxing history was Daniel Mendoza, who was born in 1764. The use of gloves was not introduced until 1860, when the Marquis of Queensberry drew up the first set of rules. Though he was technically a prizefighter, Mendoza did much to change crude prizefighting into a sport, for he brought science to the game. In this day, Mendoza enjoyed tremendous popularity. He was adored by rich and poor alike.

The public bet a great deal of money on Mendoza, but he was defeated. Mendoza met Humphries in the ring on a later occasion and he lost for a second time. It was not until his third match in 1790 that he finally beat Humphries and became Champion of England. Meanwhile, he founded a highly successful Academy and even Lord Byron became one of his pupils. He earned enormous sums of money and was paid as much as $100 for a single appear one of his pupils. He earned enormous sums of money and was paid as much as $100 for a single appearance.
