The Mangrove Nine were a group of British Black activists tried for inciting a riot at a 1970 protest against the police targeting of The Mangrove, a Caribbean restaurant in Notting Hill, West London. Their trial lasted 55 days and involved various challenges by the Nine to the legitimacy of the British judicial process.[1] They were all acquitted of the most serious charges and the trial became the first judicial acknowledgement of behaviour motivated by racial hatred within the Metropolitan Police.[2]
