Professor Gerzina explores the lives of black sailors. Life in the navy brought decent pay and promotion prospects - it could be a 'taxi service to freedom' for runaway slaves.
Professor Gretchen Gerzina explores a largely unknown past - the lives of black people who settled in Britain in the 18th and early 19th centuries.
She reveals a startling paradox - although Britain was at the heart of a thriving slave trade, it was still possible for many black people to live here in freedom and prosperity. A few even made it to the very top of fashionable society.
But there were others who were brought over by slave-owners from the West Indies and who were never free, despite living for the rest of their lives in Glasgow or Bristol or London. Some took the law into their own hands, and managed to free themselves, others went further and advocated violent revolution. Free or unfree, they all saw Britain as a place of opportunity that could become a home.
Over two weeks, Professor Gerzina travels across Britain and talks to historians, unearthing new evidence about Britain's black past. From a country estate in Chepstow, via the docks of Liverpool, to grand houses in London and Bristol, she evokes the daily texture of black people's lives, using first-hand accounts from letters and autobiographies.
In the fourth programme in the series, Professor Gerzina travels to Liverpool to explore the lives of black sailors. Life in the British Navy brought decent pay and promotion prospects - it could be a 'taxi service to freedom' for runaway slaves. But black sailors were always in danger of being kidnapped and sold into slavery.
Presenter Gretchen Gerzina is the author of 'Black in England: Life before Emancipation'. She is Dean of the Commonwealth Honors College at the University of Massachusetts.
