Sugar is grown in more than 100 countries today, and its history is, in some sense, the history of the expansion toward globalism. It took thousands of years to migrate from (probably) New Guinea to India, hundreds to then reach the Mediterranean, only scores to traverse the Atlantic, first hopping to the islands of Madeira and the Canaries, then, on to the Caribbean and the Mainland.
For readers in the United States, sugar shows up in the late 17th century or even later. England's richest American colony, Barbados, was not settled until 1630, did not start producing sugar for a generation after that. Barbadians later moved to South Carolina, bringing ideas of slavery and agriculture that influenced American history profoundly.
However, sugar had been in the New World (if you count the previously unknown islands like Madeira) for two centuries before English-speaking people became intimately concerned. The history of those two centuries is Spanish, Portuguese and African, and most of the essayists in 'Tropical Babylon' are in the Latin tradition.
The Barbadians learned about sugar from the Portuguese or perhaps the Dutch, who seized Portugal's sugar plantations in Brazil for a while. As the essayists show here, there were several sugar traditions for the English (and roughly simultaneously the French) to learn from.
The approach of 'Tropical Babylons' is primarily economic, but there is a great deal of social and even some architectural history here.
These essays are pitched to scholars and students, and fairly specialized ones at that, yet the story of sugar is rewarding in itself, so much so that a reader who 'likes history' will find a lot of miscellaneous facts, perhaps an 'ah ha!' moment or two that illuminates his understanding of better known (to readers of early American) history.
