On March 8, 1971 Muhammad Ali fought the ‘Fight of the Century’ against Joe Frazier – and lost.

But in the rematch three years later, at Madison Square Garden on January 28, 1974, Ali beat Frazier. This victory set him up for the title fight against heavyweight champion George Foreman in Kinshasa, Zaire, on October 30 of that year. Ali made history with ‘The Rumble in the Jungle’.

Muhammad Ali polarised opinion. Some say he was an arrogant sportsmen, often provoking and taunting his opponents; others a radical and anti-establishment icon who opposed the Vietnam War and fought for black rights in an America still struggling with segregation.

The exhibition ‘I Am The Greatest: Muhammad Ali’ looks back at his life. It’s on at the O2 in London. Here’s the legend below with his family, hanging out in Notting Hill and celebrating his win against Sonny Liston.
