There is also a significant Portuguese Jamaican population that is predominantly of Sephardic Jewish heritage. The first Jews arrived as explorers from Spain in the 15th century after being forced to convert to Christianity or face death. A small number of them became slave owners and even famous pirates. Judaism eventually became very influential in Jamaica and can be seen today with many Jewish cemeteries around the country. During the Holocaust Jamaica became a refuge for Jews fleeing persecution in Europe. Famous Jewish descendants include the dancehall artist Sean Paul, former record producer and founder of Island Records Chris Blackwell, and Jacob De Cordova who was the founder of the ''Daily Gleaner'' newspaper.
