full_context: Document 1: Samuel Peter: Samuel Okon Peter (born September 6, 1980) is a Nigerian-American professional boxer who held the WBC heavyweight title in 2008. He rose to prominence in his early career following a string of knockout wins, at a time when the titles of the heavyweight division were largely fragmented. In March 2008, Peter won a portion of the world heavyweight championship by knocking out Oleg Maskaev to win the WBC title. In October, in what would be his only defense of the title, Peter lost to a returning Vitali Klitschko, who stopped him in eight rounds. Peter is known for his rivalry with the Klitschko brothers, having faced Wladimir twice (in 2005 and 2010) and Vitali once.

He also held the European heavyweight title earlier in his career. Bruno was one of the most well-loved and recognisable boxers in British history, and faced multiple top-rated heavyweights during his career including two bouts with Mike Tyson and a domestic clash against Lennox Lewis. He won the WBC title in 1995 after defeating Oliver McCall at a packed Wembley Stadium. Bruno was known for his excellent punching power: he won 40 of his 45 bouts and 38 by knockout, giving him a 95% knockout rate from the fights he won; his overall knockout percentage is 84.44%.

At the time Tyson was undefeated and considered to be the best boxer in the world, as well as one of the most feared heavyweight champions in history due to his domination of the division over the previous three years. The only casino to make odds for the fight (all others declining to do so as they considered the fight such a foregone conclusion) had Douglas as a 42-to-1 underdog for the fight, making his victory, in commentator Jim Lampley's words, "The biggest upset in the history of heavyweight championship fights." Douglas held the title for eight months and two weeks, losing on October 25, 1990 to Evander Holyfield via third-round knockout, in his only title defense.

Document 10: Jack Johnson (boxer): John Arthur "Jack" Johnson (March 31, 1878 – June 10, 1946), nicknamed the Galveston Giant, was an American boxer, who—at the height of the Jim Crow era—became the first African American world heavyweight boxing champion (1908–1915). Johnson went on to become one of the most dominant champions of his time, and remains a significant historical figure in heavyweight boxing history, with his 1910 fight against James J. Jeffries being dubbed the "fight of the century." Johnson was faced with much controversy when he was charged with violating the Mann Act in 1912, even though there was an obvious lack of evidence and the charge was largely racially based. In a documentary about his life, Ken Burns notes that "for more than thirteen years, Jack Johnson was the most famous and the most notorious African-American on Earth".
Document 11: Mike Tyson: Michael Gerard Tyson ( ; born June 30, 1966) is an American former professional boxer who competed from 1985 to 2005.

He won the WBC title in 1986 after stopping Trevor Berbick in two rounds, and added the WBA and IBF titles after defeating James Smith and Tony Tucker in 1987.

Document 14: Jim Johnson (boxer): "Battling" Jim Johnson (September 2, 1887 – November 6, 1918) was an American boxer who fought as a heavyweight from 1908 to 1918. He had little success and lost with great frequency to top boxers such as Sam Langford, Joe Jeanette, Sam McVey, Harry Wills and Kid Norfolk. In spite of this (or because of it), Jack Johnson, the first black world heavyweight champion, gave him a title shot. When they fought in Paris in August 1913, it was the first time that two black boxers had fought for the world heavyweight title. Battling Jim was the only black fighter Johnson faced during his reign as heavyweight champ from 1908 to 1915.
Document 15: Tommy Burns (boxer): Tommy Burns (June 17, 1881May 10, 1955), born Noah Brusso, is the only Canadian-born World Heavyweight Boxing Champion. The first to travel the globe in defending his title, Tommy made 11 title defences despite often being the underdog due to his size. Burns famously challenged all comers as Heavyweight Champion, leading to a celebrated bout with the American Jack Johnson. According to his biographer, Burns insisted, "I will defend my title against all comers, none barred. By this I mean white, black, Mexican, Indian, or any other nationality. I propose to be the champion of the world, not the white, or the Canadian, or the American. If I am not the best man in the heavyweight division, I don't want the title."
