The first Jews in Britain were brought to England in 1070 by King William the Conqueror, while Romani in Britain have been documented since the 16th century. The UK has a history of small-scale non-European immigration, with Liverpool having the oldest Black British community dating back to at least the 1730s during the period of the African slave trade. The oldest Chinese community in Europe, dates back to the arrival of Chinese seamen in the 19th century. In the 19th century, there was an increase of Jewish and Irish people living in Great Britain, with many settling in Glasgow, Liverpool, Manchester, Birmingham and in The East End Of London, where the ethnic dialects contributed to the formation of the Cockney dialect.
