In a biographic summary of the boxer, Britannica.com details Johnson's career, stating that "Johnson fought professionally from 1897 to 1928 and engaged in exhibition matches as late as 1945." The boxer spent over a decade fighting in and out of the ring against the limitations set on him because of his race. In 1908, Johnson finally won the title as heavyweight champion after defeating boxer Tommy Burns by knockout.
However, after Johnson won the title, the discrimination did not stop. In fact, "when he became champion, a hue and cry for a “Great White Hope” produced numerous opponents." Johnson would keep up his fight for another seven years before losing his title to Jess Willard in 1915.
Jack Johnson's story does not stop there. Before his title-ending fight with Willard, Johnson was "convicted of violating the Mann Act by transporting a white woman—Lucille Cameron, his wife-to-be—across state lines for “immoral purposes.” To avoid his prison sentence, Johnson fled the country as a fugitive.
