british history. coming up, the uk's first caribbean carnival set up to showcase west indian culture. we travel back over 100 years, to hear a witness to liverpool's 1919 race riots. we meet britain's first black female head teacher. and we're in manchester to discover a legendary nightclub that became a haven for the city's black and mixed heritage communities. but we start here in the city of bristol, where, in 1963, and 18—year—old called guy bailey wanted to get a job working on buses like this one here. he secured an interview, but when he arrived, the bus company turned him away because he was black. now, despite this being racist, it was completely legal in the uk at the time. the treatment guy faced sparked a boycott of bristol's buses.
