The introduction of sugar cane from Dutch Brazil in 1640 completely transformed society, the economy and the physical landscape. Barbados eventually had one of the world's biggest sugar industries. One group instrumental in ensuring the early success of the industry was the Sephardic Jews, who had originally been expelled from the Iberian peninsula, to end up in Dutch Brazil. As the effects of the new crop increased, so did the shift in the ethnic composition of Barbados and surrounding islands. The workable sugar plantation required a large investment and a great deal of heavy labour. At first, Dutch traders supplied the equipment, financing, and enslaved Africans, in addition to transporting most of the sugar to Europe. In 1644 the population of Barbados was estimated at 30,000, of which about 800 were of African descent, with the remainder mainly of English descent. These English smallholders were eventually bought out and the island filled up with large sugar plantations worked by enslaved Africans. By 1660 there was near parity with 27,000 blacks and 26,000 whites. By 1666 at least 12,000 white smallholders had been bought out, died, or left the island, many choosing to emigrate to Jamaica or the American Colonies (notably the Carolinas). As a result, Barbados enacted a slave code as a way of legislatively controlling its black enslaved population.  The law's text was influential in laws in other colonies.
