On 9 August 1970, a group of Black Power activists led 150 people on a march against police harassment of the black community in Notting Hill, London. They called for the ‘end of the persecution of the Mangrove Restaurant’. Between January 1969 and July 1970, the police had raided the Mangrove Restaurant twelve times. No evidence of illegal activity was found during these raids. Local Police Constable Frank Pulley remained convinced that the restaurant was ‘a den of iniquity’ frequented by ‘pimps, prostitutes and criminals’.¹ At the 1970 march in defence of the Mangrove, violence broke out between the police and protestors. The following year nine men and women were put on trial at the Old Bailey for causing a riot at the march. Their names were Darcus Howe, Frank Crichlow, Rhodan Gordan, Althea Jones-Lacointe, Barbara Beese, Godfrey Miller, Rupert Glasgow Boyce, Anthony Carlisle Innis and Rothwell Kentish. These men and women became known nationally as the ‘Mangrove Nine.’ When all nine defendants were acquitted of the most serious charges after a long 55-day trial, it was widely recognised as a moment of victory for black protest. Use this lesson to find out more about the history of Britain’s Black Power movement and the trial of the Mangrove Nine. ¹ Constable Frank Pulley quoted in ‘A Den of Iniquity,’ Kensington Post, October 12, 1971, as cited in Rob Waters, Thinking Black: Britain, 1964-1985 (2019), p. 99
