Fifty years ago, on 9 August 1970, 150 protestors marched against police harassment in Notting Hill. This is the true story of the Mangrove 9, a group of Black activists who were arrested for leading the protest and who changed British history by taking a stand against racial discrimination.

Steve McQueen says “Sunday, August 9th, is 50 years since the Mangrove March, which led to nine innocent Black women and men being arrested. It was a march necessitated by relentless police brutality in Notting Hill. To commemorate the bravery of these community activists and the nine who went on to be acquitted of incitement to riot with the judge citing ‘evidence of racial hatred’, I am sharing the trailer of Mangrove, one of five films to be released under the banner Small Axe.”

Small Axe streams on BBC iPlayer this Autumn.
