Since first appearing as a hashtag in 2013, the rallying cry 'Black Lives Matter' has grown through grassroots networks across America into a powerful political movement that now has more than 40 chapters worldwide. Protesting police brutality, mass incarceration and racial disparities in all areas of American life, Black Lives Matter has spanned two very different presidencies, transforming political debate and making visionary demands for justice.

The founders of the Black Lives Matter Global Network, in Australia to accept the 2017 Sydney Peace Prize, joined the ABC's Stan Grant for an intimate conversation about the birth of the protest movement, the future of black lives under President Trump, and what lessons Australians can learn from the American experience.
