At the end of the 19th Century, African-Americans in the southern states of the US faced a wave of political and racial violence. Lynchings reached a peak. Black people were prevented from voting and subject to laws which enforced racial segregation. In response, thousands sought to leave the US and travel to Liberia. More emigrants left from Arkansas than any other southern state. We hear from Professor Kenneth Barnes of the University of Central Arkansas. He uncovered a fascinating series of letters that reveal why so many black Arkansans dreamed of Liberia and what happened to them when they got there.

He remembers how nationwide shock helped change America for good - and that it took the deaths of two white people to awake the conscience of middle America.Picture: Andrew Goodman, Credit: Associated Press

*** Contains descriptions that some listeners may find upsetting *** Enslaved Africans are forced to work in sugar cane fields - the hours are long and there are frequent, brutal punishments. They have endured these conditions for 200 years. By 1831 the anti-slavery movement is gathering pace and the slaves decide to take action - by going on strike. Samuel Sharpe became a Jamaican national hero as he led the island's slaves in a rebellion against the overseers and sugar plantation owners.The rebellion was brutally crushed, but over time, the rebellion had a significant impact - and two years later in 1833 the Slavery Abolition Act is passed.
