Enslavement of black people was rare in Ireland during the 18th century, although the legal position remained unclear until a judgement in England in 1772, the Somersett's Case. Others were tradesmen, soldiers, travelling artists or musicians. They were never very numerous, and most were assimilated into the larger population by the second third of the 19th century. They include the rebel Mulatto Jack in the Antigua Slave Rebellion (1736), the singer Rachael Baptist (fl. 1750–1775), who were both Irish. Other such as Osmond Tisani (fl. 1905–1914) were born abroad but settled in Ireland.
