It grew in just a couple of years from a hashtag to a powerful movement that has taken on police shootings of black people and is defiantly challenging the political establishment. Black Lives Matter (BLM) now has over 40 chapters in the United States and Canada. The Fifth Estate takes you inside the movement with the people who helped build it. Janaya Khan, the Toronto activist who has become its international ambassador, and Khan’s partner Patrisse Cullors – the co-founder of BLM – share their history and insights into the movement as it faces its toughest test in the face of a new Trump administration. Former members of the Black Panther Party also reflect on how they see today’s movement in light of their battles in the 1960s.
