Developing a new market
By the middle of the sixteenth century, Spanish settlers on the Caribbean Islands had
decided they needed a new source of labor. The local Indians, whom they enslaved,
had no immunity to diseases from Europe. Many were sick or weak, and too many
died.
The Spaniards began importing African slaves, who were less likely to keel over from
smallpox. (Smallpox — one of the deadliest diseases among Europeans and far more
deadly to Caribbean Indians — was also widespread in Africa, so African slaves carried
natural resistance.) The first African slaves were purchased from Portuguese ships
around 1530, beginning a trade that escalated sharply through the sixteenth and
seventeenth centuries and peaked in the eighteenth century.
Also in the sixteenth century, the Spanish found that slave labor made cash crops such
as sugar, which they could grow on Hispaniola and other Caribbean Islands, highly
profitable. And so they bought more slaves. By 1700, 4,000 slaves arrived in the
Spanish-ruled islands every year.
The English, who were building their first permanent settlement in North America at
Jamestown, Virginia, in 1607, didn’t wait long to begin importing slaves. The English
also had a labor-intensive, profitable crop — tobacco. In 1619, Virginia began using
African slaves in tobacco fields.
Portugal brought slaves to Brazil in such numbers that by 1800, half the population of
that big country was of African heritage.
