capture Puerto Rico for their         respective empires. The defeat of the British in 1797 finally thwarted that         country's designs on the island, and the Spanish colony was kept intact.         During the 16th to the 19th century Puerto Rico was characterized primarily by         underpopulation, poverty and neglect by Spain. It was mainly a garrison for the         ships that would pass on their way to or from the other and richer colonies.         During this time as much as 10 or 11 years would pass between the arrival of         ships from Spain and as trade with other countries was prohibited, the island         reverted to contraband trading with ships from England, Netherlands or         whomever would trade for the main produce of the island, which at that time         was ginger.

Slavery, however, never reached the alarming         proportions of freemen to slaves as it did on the other colonies or even on         parts of the United States. While in Haiti in 1789 the slaves comprised 90% of         the population and in Jamaica 85%, in Puerto Rico in 1834 the census         established that 11% of the population were slaves, 35% were colored         freemen and 54% were white. It was only until 1873, however, that slavery         was finally abolished in Puerto Rico....
